Do you find it difficult to read books and letters with both eyes open? If so, you might have an issue with one eye being a bit bigger than the other. Though this can be a cosmetic flaw for some people, for others it can lead to problems that are bigger than the defect itself. Depending on your personal situation, you might want to consider getting a patch made to fix it. With an extra-large eye, your vision is impaired in two different ways. The first is when looking at something far away because the spots where your eyes meet are wider apart. You end up squinting more to keep up with what’s going on around you. The second is when reading or viewing images close up because of the way the eye sits in the head. Their width and size make it hard for them to form properly aligned lines that appear straight ahead. They also result in blurring or seeing stars when reading things close up like book pages or emails that you hold in front of your face.
Why One Eye Is Bigger Than The Other?
It depends on the magnification you are using. When using a magnifying glass, one eye is typically about the size of the other. With a large-format magnifier, however, one eye can be as small as the other. This is because the smaller eye sees more detail than the larger one and can focus better.
What Causes One Eye To Be Bigger Than The Other?
- Smaller Eye
The smaller eye is typically the dominant one. It can also be a bit smaller because of injury or disease.
- Larger Eye
A larger eye can be caused by a genetic condition in which the surface of the eyeball becomes thicker than normal. The result is that it is harder to see through it, but this condition usually appears later in life and causes no other health problems.
- Hazy Vision
Hazy vision occurs when one eye sees better than the other. This happens because of an issue with the focusing mechanism and can be caused by a detached retina, cataracts, or glaucoma.
- Cataract Surgery
If you experience blurry vision with both eyes open after cataract surgery, you might have an extra-large eye (or hypertensive). This happens when one eye becomes larger than it was before the surgery, which forces your brain to focus on it more than normal when reading or viewing images close up like book pages or emails that you hold in front of your face.
- Glaucoma
Glaucoma occurs when the pressure inside your eyes increases to a point where they become damaged and can’t form properly aligned lines that appear straight ahead as they should be able to do so without any trouble at all. In some cases, this can cause them to become too large for their own good and cause both eyes to appear bigger than they really are even though only one is actually doing so.
- Intraocular Pressure (IOP)
IOP is the pressure inside the eyeball caused by fluids that flow in and out of it. It is measured in millimeters of mercury (mm Hg). When IOP increases, it puts pressure on the nerves inside the eye and can make them misfire or cause them to become paralyzed. This can result in blurry vision, double vision, or a smaller than normal pupil. IOP lessens when you get older, but it should be monitored by your doctor since it can increase again with age and cause more damage to your eyesight than before. Glaucoma Symptoms:
- Blurry Vision
If you experience blurry vision with both eyes open after cataract surgery, you might have an extra-large eye (or hypertensive). This happens when one eye becomes larger than it was before the surgery, which forces your brain to focus on it more than normal when reading or viewing images close up like book pages or emails that you hold in front of your face.
- Double Vision
Double vision is a symptom of glaucoma, but if it also occurs with only one eye open and without any blurring while looking through binoculars or reading with just one eye then there is a chance that you actually have hypertensive extra-large eyes (or hypertensive).
- Small Pupil
If you experience blurry vision with both eyes open after cataract surgery, you might have an extra-large eye (or hypertensive). This happens when one eye becomes larger than it was before the surgery, which forces your brain to focus on it more than normal when reading or viewing images close up like book pages or emails that you hold in front of your face. 4. Double Vision
Double vision is a symptom of glaucoma, but if it also occurs with only one eye open and without any blurring while looking through binoculars or reading with just one eye then there is a chance that you actually have hypertensive extra-large eyes (or hypertensive).
How To Measure Your Eye Sizes
- Place a straight edge on a wall and mark it at eye level.
- Place a tape measure over the straight edge and mark the top of the tape measure at your eye level.
- Measure from this point to your nose. You will have one number for the distance from your eye to the tip of your nose.
- Measure from this point to where you can touch with your pinky finger side-by-side (without bending) and you will have another number for the distance between your eyes (distance between index finger and thumb).
- Add these two numbers together, then divide by 2, then add 3/8 inch, then multiply by 100; this is how much space there is in front of each eyeball (remember to round down).
- Write down this number on a piece of paper or take it with you so that you can keep track of it as time goes on; do not forget to check in again in 6 months or so!
What Is The Biggest Problem Being One Eye Is Bigger Than The Other Eye?
- Be careful when driving. You may not be able to see as well in the distance, or even at night.
- If you are a pilot, take extra precautions and make sure you have a qualified pilot to fly your plane for you.
- You may have trouble seeing if there is too much glare on the road or at night.
- If there is a lot of glare from light reflecting off of something (like water) you will have trouble seeing that reflection, too!
- It can be difficult to see clearly if one eye is closer to your nose than the other one and it’s causing your facial features to shift or get confused with each other so that they look different from what they really are (called strabismus).
- You might have double vision with only one eye open (called binocular double vision).
What Is The Benefit of Being One Eye Is Bigger Than The Other Eye?
- You may have a better chance of making it through the eye exam.
- You might be able to see in more detail than you could before.
- You might be able to see more clearly at night, in the distance, or if there is glare on the road or if there is too much light reflecting off of something (like water).
- If your face and eyes are not lined up correctly your facial features may look different from what they actually are (called strabismus).
- If you have double vision with only one eye open (called binocular double vision) you will have less trouble seeing and less double vision than with two eyes open at once!
Conclusion
With an extra-large eye, your vision is impaired in two different ways. The first is when looking at something far away because the spots where your eyes meet are wider apart. You end up squinting more to keep up with what’s going on around you. The second is when reading or viewing images close up because of the way the eye sits in the head, their width and size make it hard for them to form properly aligned lines that appear straight ahead. They also result in blurring or seeing stars when reading things close up like book pages or emails that you hold in front of your face. If you have an extra-large eye, the first thing you should do is get it measured. The largest eye you have should be no larger than an A size. If your eye is bigger than that, you have a genetic mutation that causes an extra eye. The next step is to find out why your eye is so big and try to correct it.
