Did you know that around 75 percent of adults worldwide need to wear prescription glasses? Out of these, 11 percent choose to wear contact lenses while the rest wear glasses regularly. A whopping 164 million adults in America alone wear eyeglasses. From all these statistics, it’s safe to conclude that vision problems have significantly increased over the years, with more people than ever getting their eyeglass prescriptions.

If you’re one of these people, look no further, for we’ve got you covered! Today we’re expanding on the reasons you might need to wear eyeglasses along with giving you tips on how to read an eyeglass prescription. We’ll also be sharing with you the best place to get your eyes checked if you’re in Willowbrook, Houston in Texas.

Why Do You Need to Wear Eyeglasses?

Nearsightedness (Myopia)

Nearsightedness or myopia is a common eye condition that affects around 30 to 40 percent of adults in the United States and Europe. It occurs when the objects near you appear clear to you, whereas those further away appear to be blurry. This happens when your eyeball is abnormally long, or the curvature of your cornea is too sharp. Both of these conditions cause the light rays you perceive to form images in front of your retina instead of directly on it.

Farsightedness (Hyperopia)

On the other side, farsightedness or hyperopia occurs when objects near you appear to be blurry, but those that are further away appear to be clear. This condition occurs when your eyeball is shorter than it should be or your cornea is a bit too flat. This results in the light rays forming images behind the retina.

Astigmatism

Lastly, astigmatism is an eye condition in which the curvature of your eyes can cause blurred vision. In this condition, the cornea or the lens of your eye has mismatched curves, resulting in a combination of nearsightedness and farsightedness.

How to Read an Eyeglass Prescription

Now that you know why you need to wear eyeglasses, here are some abbreviations that you need to know about to understand your prescription chart properly.

OD (oculus sinister) means your left eye, whereas OS (oculus dexter) means your right eye. Recently, these terms have been changed to LE (left eye) and RE (right eye) in some clinics.
SPH (sphere) refers to the lens power prescribed to improve your eyesight. If you have a minus sign, you’re nearsighted, and if you have a plus sign, you’re farsighted.
CYL (cylinder) indicates the lens power prescribed to correct astigmatism. Similar to SPH, a minus sign means nearsighted astigmatism, and a plus sign means farsighted astigmatism.
