How Do Eyeglasses Help Your Eyes

Your eyes are the windows to your soul, at least this is what the older people say. When your eyes become dim, and weak, and can no longer see on their own, it’s time to find out why. Some common causes of eyesight deterioration are due to age, illnesses, and undiagnosed eye disorders.
In some cases, the optometrist may recommend corrective surgery to remove a foreign object, or repair a damage tissue. However, some vision problems are not that severe, and might not require such drastic treatment. In fact, the optometrist might recommend corrective eyeglasses to help improve your eyesight.
Optometrists have been prescribing eyeglasses to support, weak eyes for decades. This is normally the first type of treatment the optometrist may recommend. Nevertheless, the optometrist will not prescribe any corrective eye wear without a complete examination of the eyes first. The examination tells the optometrist a lot about your eyes, and how to treat them.
Understanding How Eyeglasses Help with Sight
To better understand how eyeglasses help with vision, you must first understand how the eyes work. The eyes help you to take in your surroundings, and what you are really seeing are different reflections of light. The light bounces off the objects, and enters through the cornea, and through the eyes lens, and eventually, onto the back of the eye, which is referred to as the retina. If the light fails to hit the retina straight on, the picture of what the eyes take in are distorted or blurry.
So, Why the Need for Eyeglass
When the light hits the retina head on, this means you have perfect vision. In cases where this does not happen, there is a potential vision problem. Some potential eye problems such as the cornea is not shaped properly, the light misses the retina when it enters through the lenses, the eyeball itself is too long or too short, or there might be some other underlying problem, the optometrist will need to find.
How Do Eyeglass Help Improve Sight
To find out the exact cause of your eye problem, the optometrist will need to perform so visual testing, using special equipment. Once the testing is complete the optometrist will write a prescription for eyeglasses. The prescription is given to the ophthalmologist, who in turn will fill the written prescription.
The prescription eyeglasses will enhance your vision, and allow by helping your eyes to refocus. When the light enters the lens of your glasses, they will redirect the light, so that it enters directly onto the retina. How much light the glasses absorbs, depends on the strength of the lenses. Strength or power in terms of eyeglasses is referred to as diopters.
The higher the level of diopters the optometrist prescribes, the greater amount of light the lenses are able to refract. In any case, once the light properly hits the eyeglass lenses in the right place, the eyes begin to see clearer, and objects are more visible, and life is wonderful, once again.
