Most Common Causes of Double Vision

Double vision, also medically known as diplopia, is when one sees a double image of something when there should only be one.  Sometimes these images can be on top of one another or side-by-side, or even a combination of both.  Double vision can affect one eye (monocular double vision) or both eyes (binocular double vision).  As one could imagine, viewing the world with double images can make managing everyday tasks very difficult.  Anything from reading, driving, to even walking or maintaining your balance.Double vision, also medically known as diplopia, is when one sees a double image of something when there should only be one.  Sometimes these images can be on top of one another or side-by-side, or even a combination of both.  Double vision can affect one eye (monocular double vision) or both eyes (binocular double vision).  As one could imagine, viewing the world with double images can make managing everyday tasks very difficult.  Anything from reading, driving, to even walking or maintaining your balance.

Double vision is caused by a number of things, some which are treatable and not too concerning, while others may be more serious.  Below are the most common causes of double vision.

Squinting.  A condition known as squinting is when the eyes are not properly aligned.  It is a condition more common during childhood and causes the eyes to look in different directions.  The eye muscles can become paralyzed, weak or have restricted movement.  In some cases, patients have experienced double vision following treatment for squinting.  This is typically the result of the brain having to work so hard to send signals to maintain “normal vision” for so long that it takes some time to adjust.

Stroke. When a patient experiences a stroke, it is not uncommon for them to also experience double vision.  The blood vessels that supply the nerves that control the eye muscles can be impacted during the stroke and patients can have difficulty seeing clearly.

Thyroid. The thyroid has been known to affect the muscles that control the eye.  For those that suffer from Grave’s disease (also known as hyperthyroidism), patients can experience double vision as a symptom.

Diabetes.  Patients with diabetes also experience a change in their vision.  The blood vessels that supply blood to the retina can be affected.  This can damage the muscle, which can cause double vision.• Diabetes.  Patients with diabetes also experience a change in their vision.  The blood vessels that supply blood to the retina can be affected.  This can damage the muscle, which can cause double vision.

Cataracts. Cataracts affect over 50% of those over the age of 80 in the United States.  Those that have cataracts have reported double vision.  Cataract surgery can help to remove the cause of the double vision. For cataracts surgery in Orange County, contact Advanced Eye Medical.

Keratoconus.  Keratoconus is a degenerative eye condition that causes the cornea to thin and begin to form the shape of a cone.  This causes the clear tissue in the front of the eye to bulge outward.  This condition can impair the vision.

Multiple Sclerosis.  Multiple sclerosis (or “MS”) can affect the nerves in the spinal cord or the brain, which may also include the nerves that control the eyes.  If this happens, one can sometimes experience double vision.

Brain Tumor or Cancer.  A tumor or growth behind the eye can damage the nerves around the eye and even prohibit movement of the eye.  This can cause double vision while the eye is unable to freely move and function properly.

Migraine Headaches.  For those that suffer from migraine headaches, a severe and often chronic form of headache that begins to take on other physical ailments, it is not uncommon to experience double vision.

Dry Eyes. When the eyes do not produce enough tears, they begin to dry out.  If they become too dry, they can become inflamed and sore.  This irritation from dry eye syndrome can result in double vision.  For those that experience chronic dry eyes, a prescription for lubricating and hydrating the eyes may help provide the eyes relief.

Temporary Double Vision

There are times when double vision is temporary. This can be anything from alcohol intoxication, seizure or epilepsy medication, or even head injuries. Head injuries are a common cause of temporary double vision. Even though the double vision may be temporary, it can still be a symptom or sign of a much more serious condition. Additionally, if you experience double vision following a head injury, it is important to seek medical treatment. Concussions can seem minor at first, but can become very serious very quickly and should not be taken lightly.


As one can see from the variety of potential causes of double vision, some may be minor or temporary and not require much care. However, others may be symptoms of much more serious conditions or health condition that may require additional medical attention. In fact, for some patients that experience double vision, it can often be the reason more serious conditions are diagnosed in the first place. This is why it is advisable to see a doctor whenever you experience double vision. He or she can check your overall health and identify and treat the root cause of the double vision.

Treatment varies and depends on the determined root cause and can range anywhere from medicine to surgery.

The Downside of Contact Lenses

Contacts are becoming increasingly popular among individuals who need to correct their vision. The appeal of not wearing glasses have led this trend, and many people think they’ll never go back to wearing glasses after trying on their first pair of contact lenses. However, as time goes on, they might be noticing some negative effects of wearing contacts that may lead them to seek out other options.

For information about eye health and LASIK in Orange County, please visit Advanced Eye Medical.

Dry Eyes

When wearing contact lenses, the quantity of tears that your eye is absorbing is greatly reduced. Instead, those tears are being absorbed the by the contacts! The lack of moisture leads to unpleasant dry eye symptoms, like itchiness, redness and a burning sensation in your eyes. If your eyes become way too dry, your cornea can even become scarred – which is very painful.

Medication Complications

The combination of using contact lenses and some medications, especially birth control pills, can result in chronic dry eye and irritation. When taking birth control, for example, and wearing contact lenses, the tear film in your eye can become damaged. The tear film consists of three main layers that work together to protect, bathe and nourish your eye. The combination of birth control and contacts can upset the balance among the three layers, causing you to feel a gritty sensation in your eye and a burning feeling due to excessive tearing.

Decreased Corneal Reflex

Contact lenses use may cause diminished corneal reflex in your eye. The corneal reflex is responsible for making sure that we close our eyes if something is threatening them, like an object flying towards your eye or someone trying to poke you. It is a protective mechanism signaled by the brain to your eyelids, telling them to close whenever any pressure is applied to the cornea.

Constant use of contacts can cause your body to ignore the corneal reflex, or may dull the body’s response to it. This can lead to all different types of eye damage because your eyes did not close fast enough.

Corneal Abrasion

Your contacts have the possibility of scratching your cornea if not fitted properly or when your eye becomes too dry, causing a corneal abrasion. You also increase your chance of a corneal abrasion when sleeping in your contacts or if you are carelessly inserting or removing them. Besides just the pain and uncomfortableness of a corneal abrasion, you might also get an infection because the abrasion creates an opening for bacteria and viruses.

Pink Eye or Conjunctivitis

Wearing contact lenses greatly increases your risk of developing conjunctivitis or a sty, especially if you sleep in them. Contacts provide a moist environment that acts as breeding ground for bacteria and viruses. And since less oxygen reaches your cornea when wearing the contacts, your body cannot fight off the infection as effectively as it could.


A condition where your eyelids start to droop, ptosis can lead to the affected person not being able to open their eyes fully. The contact lenses can move into the eyelid tissue, causing scarring and contraction.

What You Can Do

First, you can start wearing your contact lenses less, and use your glasses more regularly – at the very least make sure to always clean your lenses and do not sleep in them. However, if you are one of the many people that switched to contact lenses to stop wearing your glasses, there is another option for you: Lasik surgery. This surgery is done to correct your vision, and frees you from having to wear your glasses or contacts. For this reason, it is a good idea to talk to your eye doctor about the undergoing the procedure.

How to Improve Your Night Vision

As you begin to age, the ability to see clearly at night can begin to deteriorate. This is a common condition referred to as night blindness (or nyctalopia). The good news is that there are some things that you can do to improve your night vision.

For more questions regarding eye health and information on LASIK in Orange County, trust the experts at Advanced Eye Medical.

Causes of Night Blindness

Night blindness is the result of a disorder of cells near the retina. Several eye conditions that seem to develop in people as they age also seem to be the cause of night blindness, which is why night blindness seems to be a disorder that comes with age. Some common causes of night blindness include myopia (or nearsightedness), macular degeneration (cataracts), glaucoma, glaucoma medications (which close the pupil), diabetes, as well as a deficiency in Vitamin A.

To determine what may be the cause of night blindness, one should seek out the help of an eye doctor who may run specialized tests to pinpoint the root cause of the poor night vision.

Impact of Night Blindness

It is important to note that night blindness does not merely imply the time of the day. Night blindness is related to the amount of light available, which means that poorly lit rooms are also a problem. For those that suffer from night blindness, everyday tasks can become extremely challenging. Anything from driving or walking at night, to trying to read or knit at home.

Obviously, not being able to do some tasks at home can be frustrating, but being unable to drive or walk at night can be very dangerous. The result is that some people who suffer from night blindness begin to stay at home, too afraid to go out at night with the inability to get themselves home safely. This can wreak havoc on their self-confidence and social life.

Ways to improve Night Blindness

The good news is that there are some things that you can do to help improve your vision at night. Here are some things that you can do to improve your night vision:

Avoid Looking at Bright Lights

Whenever your eyes are exposed to bright lights, it forces the pupils to contract. By doing this, it increases the amount of time that it takes for your vision to adjust to the low light. This is one of the reasons why driving is such a big concern for those with night blindness. While driving, it’s very easy to become literally blinded from the headlights and bright lights that can be unavoidable while driving. It becomes very challenging to adjust again to the low light and that’s not a place where you want to be if you’re behind the wheel. If bright lights are unavoidable, cover or close your eyes until the bright light passes. By protecting your eyes from these bright light sources, you will help your eyes avoid the struggle to become acclimated to the low light. (Also, you should never, under any circumstances, look straight at the sun!)

Increase Your Vitamin A Intake

Vitamin A deficiency has been linked to night blindness, so by increasing your Vitamin A intake, you can help to improve your night vision. You can do this with the help of dietary supplements, as well as through natural sources of Vitamin A, including dairy products, liver, fish, carrots, broccoli, squash and cantaloupe.

Adjust Your Eyes to Darkness Naturally

One of the best ways to help your eyes learn to see in the dark is to let your eyes slowly and naturally adjust to low light. The best way to do this is by sitting in complete darkness for at least 20 minutes before going out at night. You can also cover your eyes or use a sleep mask to help aid this practice.

Blink Often and Keep Your Eyes Moving

When you are out where it is dark, it is helpful if you keep blinking and keep your eyes moving, not allowing your eyes to focus on the available light source on any one object you may become focused on. For example, think about when you may be sitting in a car at night and if you pull out your mobile phone. After staring at the bright light omitted by your phone, you may notice some time needed to adjust your eyes when you look away from your phone. The same thing happens when you are out and begin focusing your eyes on other forms of light sources.

Give Your Eyes a Gentle Massage

Close your eyes tightly or apply slight pressure on both of your eyes with your palms. Do not press too hard. After about 5-10 seconds, your vision will momentarily turn white and when the white goes away, the black will come back. You can then open your eyes and your vision will be significantly improved in the dark.

Use Red-Tinted Glasses

Red-tinted glasses are used to help with improving night vision, as it helps to train your eyes to focus better. This is a common trick used by pilots and aviators. Also, it may be helpful to find a vehicle that utilizes red dashboard controls and buttons, over blue, green or white ones.

The above tips may be helpful to improve your night vision, but if you are and/or continue to struggle with night blindness, none of these tricks should replace medical treatment recommended by a licensed medical professional who can properly diagnose and treat you for your symptoms.

Can Rubbing Your Eyes Harm Your Vision?

Rubbing your eyes are a natural reaction that just about everyone does.  Whether it’s because you feel like you have something in your eye, you just woke up, you are sleepy, or you feel like your eye is itchy, rubbing the eyes seems to be one of the only things that feels like an immediate source of relief.  Some people even rub their eyes when they are stressed out or anxious.  Rubbing of the eyes can also come in many different forms—from one to multiple fingers, knuckles, to the palms of the hand. For more information about eye treatment in Orange County, utilize the services of Advanced Eye Medical.

All that being said, one question you may (or may not) have considered is whether rubbing your eyes can actually do any damage to your eyes and vision.

The answer to this, like many things in life, is…it depends.

The sporadic, momentary rub of the eye is not usually too much reason for concern.  In fact, this occasional rubbing of the eye is known to have some benefits.  One of the reason why rubbing the eyes when they feel dry or itchy is such a natural reaction is because it results in the production of tears to help lubricate the eye and provide some relief to the eye.  This can help to remove dust or other particles that may be irritating the eye.  Pressing down on the eyeball stimulates nerves which can slow down the heart rate, which can provide some form of stress and anxiety relief. For a list of remedies to common eye problems, seek eye treatment in Orange County.

This all sounds like great reasons to rub your eyes, but here’s when rubbing your eyes can be harmful.

Too Much Pressure

One of the ways that rubbing the eyes can be harmful is when you put too much pressure on the eyeball.  By rubbing your eyeball too hard and for too long, you increase eye pressure.  This increase in pressure to the eye can be troublesome for those with short-sightedness.  In some cases, patients have actually experienced the detachment of the retina which can be extremely dangerous and cause for concern.  Additionally, patients with glaucoma can experience a disruption in blood flow due to an increase in eye pressure.  This can then lead to nerve damage, which can then ultimately affect your ability to see properly (or at all).

Infecting the Eye

Another more common harmful side effect of eye-rubbing is the potential risks of infecting the eye.  People carry numerous germs on their fingers, underneath their nails and cuticles, and on their hands.  Every time you rub your eye, you put your eyes at risk of getting these germs in the eyes and infecting the eye.  Then, once the eye is infected, if not properly treated, you potentially risk damage to your eyes and vision.

Additionally, if you continually rub your eyes, you can also risk scratching the surface of the eyeball with your nails if you are not careful or gentle in the way that you rub.

In conclusion, while eye-rubbing is a natural reaction, there really is no reason to ever have to rub your eyes and being more mindful and aware of when you do rub your eyes is a great way to eliminate this behavior.  Here are some common substitutions for rubbing your eyes in various situations.

  • Something in Your Eye. If you feel like you have something in your eye, the best way to get it out is by washing your eyes out with cool water.  This will help to naturally flush out anything that may have gotten into them.  Additionally, if you work around a lot of dust, chemical, or particles, it would be good to consider wearing safety goggles to protect your eyes before you get something into them.
  • Dry, Itchy Eyes. If your eyes are dry and itchy, the best way to treat them is through the use of eye drops to help lubricate and rehydrate your eyes. If you notice that your eyes are dry and itchy often, you may also want to seek the help of an eye doctor to check and make sure that there’s nothing else wrong with your eyes that may be causing the dry eyes.
  • Stressed or Anxious. Stress and anxiety are bound to happen, so figuring out a way to find a healthy outlet to manage your stress and anxiety is key to avoiding adding any additional concerns to your life by potentially causing any harm to your eyes or vision. From breathing techniques, meditation, and physical activity, there are a number of ways to better manage your stress than to take them out on your eyes!

How iLASIK is Customized for You

If you are tired of depending on contacts and glasses, then you might be thinking of getting surgery to correct your vision. Improving your vision with Lasik surgery in Orange County can be a great option for some people and can even improve their quality of life.

iLasik surgery is different from traditional types of Lasik surgery. iLasik combines all the latest technology into one comprehensive eye procedure, and uses advanced technology for a more precise outcome. There are also less complications with this procedure, making it a great option for everyone who meets the surgical requirements.

The Difference Between Traditional Lasik and iLasik

In traditional Lasik eye surgery, your doctor uses two steps to complete the surgery. To begin, the flap in your cornea must be created with a small metal blade. Then, the laser vision correction treatments occur underneath the flap on the inner layer of your cornea. The metal blade used to make the corneal flap was traditionally created with a hand held mechanical device called a microkeratome. This device was sufficient for a number of years for the surgery, however it could sometimes be unpredictable. Complications in Lasik surgery are rare, but were created by this device most of the time.

With iLasik, your doctor will use a precise laser to create the flap in your cornea, making this a completely blade-free surgery. The laser is extremely accurate, +/- 10 microns, and is the most advanced technology currently used for this procedure. It creates the flap by producing tiny bubbles inside your cornea. The consistent accuracy of the laser means that people who have thin corneas and may have been previously told they were not eligible for surgery could potentially have this procedure done.

How iLasik Customizes Each Procedure

The iLasik surgery is completely customized for each patient. The advanced procedure uses the VISX Wavescan System to create a vision profile for each patient, including a 3-D digital map of your eye. The laser relies on this map as it creates the flap in the cornea, shapes the cornea and fixes your vision.

The vision profile creation is the first step in the iLasik surgery, and uses a series of tests to determine your unique vision characteristics using the Wavescan system. The system then creates a 3D map of the imperfections in your eyes, which is 25 times more precise than standard prescription measurement tools used for glasses and contacts prescriptions.

Surgical Requirements

Since the iLasik procedure is available pretty much everywhere, you may be wondering if you are a good candidate for the surgery. The technology used for iLasik is safe, FDA approved and proven to be effective. It is a fast and simple procedure, and most people who meet the basic requirements are eligible for iLasik surgery. While there are risks that are associated with any surgical procedure, iLasik is safe and your doctor can talk to you about the risks.

You may be a good candidate for this surgery if you meet these requirements:

  • Age: You need to be at least 21 years old.
  • Health: You must be in good, general health with no existing eye diseases.
  • Prescription: This procedure treats mild to severe nearsightedness, farsightedness and astigmatism. Your prescription must be stable for at least a year.

If you think you are a good candidate for Lasik surgery in Orange County, make sure to contact Dr. Ghosheh and the team of dedicated eye care experts at Advanced Eye Medical.

How Does Dry, Cold Weather Affect Our Eyes?

When the weather gets cold, we all remember to put on our scarves, boots and heavy coats. However, you may be forgetting to protect your eyes from the harsh weather as well. The winter season can bring about some uncomfortable and irritating symptoms for your eyes. If you ever feel like your eyes bother you particularly in the cold, winter months, you’re definitely not alone. Lots of people struggle with dry, itchy eyes during the winter.

Dry Eyes

With all the dry wind and cold temperatures, your eyes can quickly become dried out. In extreme conditions your eyes cannot keep up with producing enough tears to keep you comfortable. And if you think escaping the cold weather indoors will help, think again. In most homes, offices and businesses, the humidity levels will be lower because the heat is on and the windows are closed.

To combat your dry eyes, you should try a few things:

  • In windy weather or when exercising outside, protect your eyes with glasses or goggles.
  • Using a humidifier can help keep/add moisture to air and keep your eyes from drying out. As a bonus, using a humidifier when you get a winter cold can also help you feel better.
  • To stimulate tear production, you can take omega-3 supplements.
  • Your doctor can prescribe you eye drops that will lubricate your eyes.
  • Decrease some medications that can reduce your ability to produce tears, like antihistamines, sleeping pills and pain relievers.

Excessive Tearing

Some people notice that their eyes tear up more in the winter time and during a windy day rather than their eyes drying out. This can cause some annoyances, like constantly rubbing or wiping your eyes and your vision becoming blurry.

So, what do you when your eyes won’t stop tearing up? Try this:

  • Where sunglasses or goggles while outside, or at the very least while playing sports outside, like you would with dry eyes.
  • When you wipe your eyes, make sure that the cloth you are using is clean. Otherwise, you may be making the tearing worse by adding dust or dirt particles into the mix. You could also potentially spread germs if the cloth is not clean.

Swollen, Red eyes

Another symptom people may notice during cold, windy weather is their eyes becoming red and swollen. This may happen because the blood vessels in the tissue around the eyes can become constricted. This can also lead to other unpleasant symptoms, like blurry vision, eyelid spasms or excessive tearing.

To help de-puff and bring your eyes back to a normal color, try this:

  • Again, wearing sunglasses or goggles while outdoors can greatly help your eyes return to normal. It’s important that these glasses have UV protection, especially in the winter when UV rays can be reflected from the snow and ice on the ground.
  • Your doctor can prescribe you eye drops that will help your eyes.

Burning Eyes

If the weather is extremely cold, make sure not to force your eyes open as your cornea can actually freeze. This will result in pain, blurry vision, eyelid spasms and sensitivity to light.

To help your eyes, try this:

  • Like before, make sure to wear protective sunglasses or goggles when outdoors in extreme temperatures.
  • If you are experiencing any pain or a strong burning sensation, make sure to contact your doctor immediately.
