Why Is One Eye Blurry While the Other’s Clear?

Blurred vision in one eye as a symptom may be an indication of something entirely different from blurred vision in both eyes. While blurred vision in both eyes may be a sign of aging or the need for vision correction, the former might be something more serious. It could still be a non-serious cause, like discharge from one eye or crying.

However, one thing is certain: you should consult your ophthalmologist promptly if you wake up with blurry vision in one eye and it doesn’t clear up soon. Let’s go through the possible causes of blurry vision in one eye and the solutions for that.

Reasons Behind Blurry Vision in One Eye

Blurry vision is more than discomfort. It can be confusing and even a little alarming. Many of us think that blurry vision is a minor issue, like eye strain or dryness. But this is something which also gives a signal that needs attention. It is important to learn the causes early to get proper treatment and prevent further vision issues. Here are some of the most common reasons this might happen.

Refractive Errors

This can be anything from myopia (nearsightedness) and presbyopia (farsightedness) to astigmatism. The good news is that all three can be managed with the use of prescription glasses. Astigmatism occurs because of an irregularly shaped cornea; the light rays can’t focus on a single point on the retina, leading to blurred vision at all distances.

If you already have a prescription for long-sightedness and have now been advised to use reading glasses, you might consider varifocal lenses. These advanced lenses provide clear vision at all distances, like near, intermediate, and far, making them a convenient all-in-one solution.

Cataract

Cataracts make the lenses of our eyes opaque or cloudy, leading to blurry or double vision. Usually, it’s a natural part of ageing, and most people experience cataracts in their 60s. However, there can be other reasons like exposure to UV rays from the sun or injury which can lead to the condition at a young condition.

Migraine or Optic Neuritis

Blurry vision in one eye and a headache can be a result of a disorder in the nervous system or brain, like migraine or optic neuritis. Migraine is a neurological condition that causes intense headaches. It is often genetic, so check if someone in your family has had it. Optic neuritis is the inflammation of the optic nerve, which can cause blurry vision in only one eye at first.

Diabetes

Along with other conditions, diabetes can be responsible for one eye-related issue called diabetic retinopathy. Because of high blood sugar levels, the tiny blood vessels in your retina can be damaged. It can lead to blurred vision or even loss of vision if left untreated. Please note that this condition can be detected as part of regular eye tests, since your optometrist or ophthalmologist might observe these blood vessels at the back of your eye.

Stroke

One of the definite ways to tell if someone is having a stroke is if they are having sporadic and painless alterations of vision, with blurry vision in one eye. If accompanied by other symptoms such as face drooping, slurred speech or numbness, immediately call 999.

Psoriasis

The usual symptoms of this condition are related to the skin, but it can affect the eyes as well. Inflammation causes sensitivity to light and blurred vision in one or both eyes.

Multiple Sclerosis

Blurred vision is actually an early warning sign of multiple sclerosis. It leads to the inflammation of the optic nerve, which can cause pain in the rolling eyes and loss of colour vision as well. Other symptoms include dizziness, fatigue, problems with balance and stiffness.

Wrapping It Up

The causes and conditions discussed above vary in their seriousness. Early detection becomes very important in all the mentioned cases. Make sure to go for regular eye tests every two years. You can book a free eye test at your nearest Specscart store if you live in Manchester or nearby. Whether the solution is glasses or surgery, early diagnosis will help manage the condition better.
