Prescription eyewear (otherwise known as eyeglasses, prescription sunglasses, or contact lenses) works by bending light as it enters your eye to allow it to focus perfectly on your retina for a crystal clear viewing field. To better understand this process, we first need to understand how the eye itself functions.
Your eye has a series of internal mechanisms that allow light to be transferred to your optic nerve to create images. This system includes the pupils, cornea, lens, and retina. When you look at a beautiful naturescape, for example, this happens:
If we can say anything about the human eye, it is beautifully complex!
It may seem straightforward: if you look around and the world appears blurry, you need glasses. But, in many cases, it’s not that simple. Many people do not realize they would benefit from corrective lenses until they show up at their doctor complaining of neck pain and headaches from straining to see.
Fun fact: 75% of Americans need corrective lenses (otherwise known as eyeglasses, prescription sunglasses, or contact lenses) to keep their surroundings in focus.
If a person is experiencing age-related vision problems, the changes may be so gradual, they do not realize them day to day. It is always a good idea to have a yearly check-in with an optometrist or ophthalmologist. They will run a series of tests to determine the health of your eyes, if you suffer from any kind of vision problems, and if you need glasses or corrective lenses. Your eye doctor will present you with a chart containing your prescription and will have measurements for your left eye, right eye, and whether or not you suffer from astigmatism. For more on how to understand your eyes’ needs, see our guide on how to read your prescription.
In most cases, you will adjust to your new eyeglasses prescription in about two to three days. If you wear your new glasses for a few weeks and are experiencing headaches, neck pain, light sensitivity, or other adverse side effects, you should consult your eye doctor to make sure the prescription is correctly suited to your needs.
