Are Eye Prescriptions Necessary?
Prescriptions for eye glasses and contact lenses are necessary because the vision acuity of people changes as they get older, become involved in various activities, and eye muscles change.
Comprehensive eye examinations cover a lot more ground than just getting the correct measurements for eyeglasses. When an eye doctor gives a patient a thorough eye exam, a series of tests that are complex are given which check the overall eyesight of the individual, eye pressure, neurological function, the coordination of the eye muscles and the overall internal and external structure of the eye.
It is important for you to wear the correct prescription glasses, or you might get headaches, or have difficulty seeing. Many people will go to the big box store and pick up some “reading glasses,” and if things look good while looking through them, they buy them and use them, instead of going to the eye doctor.
This may work for a while, but the older we get, the more we should rely on a professional opinion because eye health is more involved than just getting the right prescription. While the eye doctor is giving you an eye exam in order to get the proper prescription, you are also being examined for any eye disease that might be present.
Glaucoma is a disease that can cause you to go blind if you let it go and are never tested for it. You cannot feel any pain from glaucoma, but gradually you will lose vision. The loss of vision is gradual, but eventually, the individual will lose their peripheral vision and develop “tunnel vision.”
There is a form of glaucoma that causes severe pain and blurring of vision, and this is a medical emergency and blindness can occur in one or two days.
Macular degeneration is another eye disease which is the leading cause of vision loss in the United States. The eye doctor can find this condition during a routine eye exam and then you can get help in combating the condition.
Many of us have never had any problem with our eyes, but when we get a little older, say from our forties on up, we need to pay more attention to our eye health. And that includes getting the correct prescriptions for our glasses and contacts.
It really doesn’t make sense to be wearing the wrong prescription level glasses when it is so easy to have it done correctly. Being able to see will affects every part of our lives from reading, having the ability to read thefine print on labels at the store, driving at night, and a host of other tasks we are involved with that require good vision.
In the process of having our eyes checked, it is a given that the eye doctor will be able to find out the state of our overall eye health too. If we do have a more serious condition developing, such as glaucoma or macular degeneration, we can then take steps to counteract the progression of the disease.
