Refractive Errors

What are refractive errors

In order for our eyes to be able to see, light rays must be bent, or refracted, by the cornea and the lens so they can focus on the retina, the layer of light-sensitive cells lining the back of the eye.

The retina receives the picture formed by these light rays and sends the image through the optic nerve to the brain.

A refractive error means that due to its shape or to changes in the function of the lens that occur with age, your eye doesn’t refract the light properly, so the image you see is blurred.

The most common refractive errors are Astigmatism, Hyperopia, Myopia, and Presbyopia.
