Refractive Errors

Your eyes, cornea, and lens may all be shaped just well for the light rays to bend and land on your retina and make their way to the brain. If this process does not go all well, vision gets blurred, causing refractive errors, such as myopia (nearsightedness) or hyperopia (farsightedness).

Refractive errors are vision problems caused by a deviation in the shape of the eye that prevents light from being focused correctly on the retina, resulting in blurred vision.

The most common types of refractive errors are:

Hyperopia – farsightedness

Hyperopia is when someone can see distant objects clearly, but up-close objects appear out of focus. This occurs when light rays focus directly on the retina’s surface, and the light focuses behind the retina.

Myopia – nearsightedness

Myopia is when someone can see up-close objects clearly, but distant objects appear out of focus. This occurs when light rays focus at a point in front of the retina rather than on its surface, causing light to focus too far in front of the retina.

Astigmatism

Astigmatism is a condition in which the eye has an irregular shape, causing blurred or distorted vision at all distances.

Presbyopia

Presbyopia is a condition that affects people over the age of 40 and is caused by a loss of flexibility in the eye’s lens, resulting in difficulty focusing on close-up objects.

Refractive errors can be corrected with glasses, contact lenses, or refractive surgery. It is important to have regular eye exams to detect and correct any refractive errors to avoid eye strain and other complications. Is it your time to see your eye specialist?

Astigmatism

A common vision disorder causes the blurring of your vision when your cornea is irregularly shaped or there is an irregular curvature of your lens inside the eyes. It is a common and easily treatable imperfection in the curvature of your eyes that causes blurred distance or near vision. In it, the cornea and the lens of your eye have mismatched curves.
