Modern prescription glasses are lightweight, durable, and more accessible to the general public than it was a few decades back. That's because of the shift from glass to polycarbonate lenses in the mid-1900s. The lens is crafted in the optometrist's office once the patient goes through an examination to determine the strength of the lens. If you are wondering whether prescription glasses are important, you have come to the right place. This article provides information on the reasons prescription glasses are important.
Vision Test For Prescription Glasses - Pensacola
The basic vision test is one of the most important eye examinations conducted by a qualified optometrist. One of the main conditions the eye doctor is checking for is a refractive error. A refractive error is an abnormality in the shape of your eye. This changes the eye's capacity to focus light onto the retina. This can lead to blurred vision - which can be easily corrected with a pair of prescription eyeglasses.
Prescription Glasses For Refraction Error
Refraction error is a problem with the process of refraction that's responsible for sight. The light rays that enter your eyes are refracted or bent through the cornea and lens. That way the light focuses on a single point in the retina. From this point, a message is sent to the brain via the optic nerve to interpret the signals into the images we see.
There are different types of refractive errors such as:
Myopia or nearsightedness - where the length of the eyeball is too long and results in the light focusing in front of the retina. If you have this condition, you can see when objects are close but not when they are at a distance.
Hyperopia or farsightedness - where the length of the eyeball is shorter than normal. This will result in near objects being blurry. This condition can result in eye strain and fatigue when looking at near objects for a long period.
These are some reasons you need to wear prescription glasses prescribed by a qualified eye doctor. Don't buy cheap eyeglasses that are on the market. You should never compromise the quality of your eyesight by wearing such eyeglasses. Make sure you wear prescription glasses from a qualified eye doctor.
