  • Nearly 75% of the American population requires some form of vision correction. The medical profession catalogs the most common conditions as myopia, hyperopia and astigmatism. Let’s take a moment to learn about how our eyes work to focus clearly, and how prescription lenses can help to correct these common refractive errors.

    Your eyes work with your brain to focus on light, similar to how a movie projector focuses images on a screen. In this analogy, the movie screen is the retina located at the back of the eyeball.  Light from the objects you are viewing enters the eye first through the transparent and dome-shaped cornea, then through your lens, on its way to the retina at the back of the eyeball. When the eyes focus correctly, the light rays are focused perfectly onto the surface of the retina, just like the screen in a movie theater.

    Nearsightedness – or myopia – results when light rays are focused on a point in the eyeball somewhere in front of the retina. Consequently, the myopic eye can focus clearly on objects up close (hence they are “nearsighted”), but objects in the distance appear blurry.

    Farsightedness – or hyperopia – results when light rays are focused on a point beyond the retina. In this case, the hyperopic eye can focus clearly on objects farther away while objects up close appear blurry.

    An eye that focuses correctly has a cornea that is spherical-shaped. Astigmatism refers to a misshapen cornea that is not spherical which causes light to bend and therefore focus on a point either in front of or behind the retina. Often the astigmatism produces two different focal points for the light entering the eye. Individuals with a more severe astigmatism may see objects that appear to be bent or distorted in addition to blurry. 

    Your vision prescription can tell you what refractive error your lenses are correcting. “+” numbers in the Sphere column correct for hyperopia or farsightedness; “-“ numbers correct for myopia or near-sightedness. A number in the cylinder column means your lenses correct for astigmatism.

    Now that you have a better understanding about common refractive errors and how to interpret your vision numbers, we invite you to learn about the different lens materials we offer and which one is best for you.

    What are progressive glasses, who needs them and how do they help people see more clearly

    Progressive glasses are typically prescribed to individuals who have difficulty seeing both near and far. This condition is known as presbyopia and it usually occurs as people age. Presbyopia is a natural part of the aging process and typically begins to develop around the age of 40. If you find yourself holding things further away to read or switching glasses frequently, you may be a candidate for progressive glasses.
