Visual Impairment

Which Visual Impairment Occurs In Almost Everyone?

Visual impairment is something that can happen to anyone at any age. It is estimated that more than 4 million Americans are visually impaired.

There are many different types of visual impairments, but the most common is refractive error. In simple terms it is called blurry vision which can treat with medication, purchase it from

Refractive error is when the eye does not focus light properly on the retina, which is the part of the eye that helps us see.

This can lead to blurry vision or difficulty seeing at night. Other common types of visual impairment include presbyopia, astigmatism, and color blindness.

While these conditions may seem minor, they can actually have a big impact on a person’s life.

This can cause things to look blurry or out of focus. Other common visual impairments include cataracts, glaucoma, and macular degeneration.

Blurred Vision: Causes And Treatment

Myopia: Symptoms of myopia include squinting, eye strain, headache, and blurred vision in one or both eyes. Myopia is the most common refractive error and causes distant objects to appear blurry.

Glasses, contact lenses and refractive surgeries such as LASIK and PRK are the most common ways to correct nearsightedness.

Hyperopia: If you have hyperopia, distant objects may remain clear but your eyes may not focus properly on nearby objects – or doing so causes unusual eye strain and fatigue.

In cases of severe myopia, distant objects may also appear blurry.

Like myopia, hyperopia can also be corrected with glasses, contact lenses, or refractive eye surgery.

Astigmatism: Blurred vision at all distances is often a symptom of astigmatism. Astigmatism, which is a type of refractive error, is usually caused by an irregularly shaped cornea.

With astigmatism, the rays of light fail to hit a single focus point on the retina to provide clear vision, no matter how far the object is from your eye.

Astigmatism, like nearsightedness and farsightedness, can be corrected with glasses, contact lenses or refractive surgery.

Presbyopia: If you are over 40 years old and you are beginning to see blurred vision of close objects – for example when reading a text message, restaurant menu, food label, or other small print – So the possibility is that this is due to the onset of presbyopia, which is a common age-related vision problem.

While the symptoms of presbyopia are similar to those caused by hyperopia (blurred near vision, eye strain when reading), presbyopia is an age-related decrease in the ability to focus on near objects that form the lens inside the eye.

Common treatments for presbyopia include progressive lenses, multifocal contact lenses, bifocals, and reading glasses.

There are also surgery options for presbyopia – including corneal inlays, presbylasic and conductive keratoplasty.

In all glasses that correct refractive errors and presbyopia, clarity and comfort can be enhanced with anti-reflective coating and photo chromic lenses. Talk to your optician for details.

Chronic Dry Eyes: Dry eye syndrome can affect your eyes in many ways, including having variable blurred vision.

While artificial tears (lubricating eye drops) may help, more advanced cases of dry eye may require prescription medication or punctal plugs to keep your eyes comfortable, healthy, and well visible.

Pregnancy: Blurred vision is common during pregnancy and is sometimes accompanied by double vision (Diplopia or double vision).

Hormonal changes can change the shape and thickness of your cornea, causing your vision to become blurry. Dry eyes are also common in pregnant women and can lead to blurred vision.

You should report any disturbance in vision during pregnancy to your optician. While blurred vision isn’t always serious, in some cases it can be a sign of pregnancy-related diabetes or high blood pressure.

Ocular Migraine Or Migraine Headache: While usually harmless and temporary, blurred vision, twinkling lights, aura, and zigzag patterns are all common symptoms before the onset of an ocular migraine or migraine headache.

Eye Floaters: Vision can be blurred with temporary spots or floaters that keep flowing in your field of vision.

Floaters usually appear when the gel-like vitreous of the eye begins to liquefy with age, causing microscopic pieces of tissue within the vitreous to float freely inside the eye, forming a retina. But a shadow begins to appear.

If you notice a sudden shower of floaters, it could be a sign of a torn or detached retina and you should see an optician immediately.

Blurred Vision after LASIK: Your vision may become blurry or unclear immediately after LASIK or any other type of refractive surgery.

The clarity of your vision will usually improve within a few days, but it may take longer for your vision to become completely stable.

Eye Drops And Medication: Some eye drops – especially eye drops containing preservatives – can cause irritation and blurred vision.

Also, some medicines like allergy pills can cause side effects of dry eyes and blurred vision.

During a comprehensive eye exam, your optician can advise whether any of your medications may have caused the blurred vision.

Over-Wearing Of Contact Lenses: Wearing disposable contact lenses (or any type of contact really) for longer than prescribed by your optician will cause proteins and other debris to build up in your tear film in the lens.

This can cause blurred vision and increase your risk of eye infections.
