Common Eye Conditions & Their Effects To Your Eyesight

Your blurry vision may have been caused by one of the most common eye conditions. Blurred vision or loss of vision can be caused by any condition.

Many people wrongly assume blurred vision is a result of age (and it can be), and avoid getting their eyes checked or seeking treatment. Many common eye conditions leading to poor vision, such as cataracts, can be treated and vision can be restored when the condition is diagnosed early.

If you experience blurred vision or vision loss, it may be due to any of these common eye conditions:

Refractive Errors

The most common eye conditions resulting in poor vision and a need for vision correction are refractive errors. Nearsightedness, farsightedness and astigmatism are all types of refractive errors.

Astigmatism is a common refractive error wherein the cornea and lens of the eye are unevenly curved. An equally curved eye will properly refract light, allowing clear vision, but an irregular shaped cornea or lens can affect vision.

Due to the irregular shape of the eye caused by Astigmatism, the eye’s ability to focus is inhibited. So, images may appear distorted or blurred.

Symptoms of astigmatism include blurry vision, eye-straining, headaches and squinting to see clearly. Mild to moderate astigmatism is most commonly treated with eyeglasses or contact lenses. In some more serious cases, LASIK eye surgery can treat astigmatism by reshaping the cornea. Reshaping of the cornea will improve how the eye focuses light rays on the retina.

Myopia (nearsightedness) is the most common refractive error of the eye. It occurs when the eyeball is too long relative to the focusing power of the cornea and lens of the eye, or the cornea and/or lens is too curved for the length of the eyeball, or a combination of both factors. As a result, the cornea and lens bend incoming light rays so they come into focus in front of the retina instead of directly on the retina. A person with myopia can clearly see close-up tasks, like reading and using a computer but has difficulty seeing distant objects clearly.

Hyperopia (farsightedness) occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina. The cornea and lens bend incoming light rays so they come into focus behind the retina rather than on it. Hyperopic eyes can see objects clearly from a distance but near objects appear blurry.

LASIK surgery is excellent in terms of correcting refractive errors as it effectively changes the shape of the cornea so that the eye will properly refract light into a point of focus on the retina.


Presbyopia is a common type of vision disorder that occurs as you age. It is often referred to as the aging eye condition. Presbyopia results in the inability to focus up close, a problem associated with refraction in the eye.

It is due to hardening of the lens of the eye causing the eye to focus light behind rather than on the retina when looking at close objects.


A cataract is the clouding over of the focusing lens of the eye, which is located behind the pupil. Symptoms of cataracts include: blurred vision; difficulty seeing street signs, curbs, freeway exits and traffic lights; seeing halos or glare around lights; difficulty seeing TV, movies or faces; difficulty reading and more.

Cataracts can be treated with cataract surgery. To restore vision that has been lost or impaired by a cataract, the cloudy lens must be removed and a clear plastic implant lens replaces the cloudy lens.
