Sunset District Eye Doctor

Sunset District Eye Doctor

Our Sunset District eye doctor, Edward Soss, OD, explains to our patients that unlike an eye test, an optical prescription is not a straight measurement of your ability to see. It does not compare eyesight with someone who has perfect vision, the way an eye chart does. Instead, the numbers on your prescription are the specific power that is needed to correct your vision to normal. At Dr. Soss is more than happy and capable to explain your numbers to you and that eyeglass and contact lens prescriptions are not the same. Whatever your preference, we will help you to understand your needs so together we can achieve your goals. Basically, with an accurate optical prescription, corrective lenses bend the light rays to focus more directly onto your retina. The amount of correction necessary is written as a prescription.

If you wear glasses, you certainly know they help you to see better, but you may not know how they specifically correct your vision. Whether for nearsightedness or farsightedness, eyeglasses work in the same way. When the lens in your eyeglass is curved, it bends the light rays that hit your eyes, so you can see images clearly. Our Sunset District eye doctor wants all of our patients to know that understanding how glasses correct your vision, begins with a basic understanding of how your eye works. At the back of your eye is your retina, which is a layer of cells that reacts to light. The reaction is sent to your brain, and your brain translates the cells activity into an image, or the thing that you actually see.

When you look at something, the light rays come together, or focus, inside your eye. When you have perfect vision, the light rays focus directly on to the surface of the retina. Because the retina is curved, the image must also shrink, and needs to be curved, because the retina is curved. Your pupil and cornea are responsible for shrinking, focusing, and curving the image and if any of them have any irregularities, your vision will be blurry. Eyeglass lenses are curved pieces of glass and the curvature of the lens bends the light rays as they move towards your eye. This helps the rays focus on your retina, instead of behind or in front of it. Our Sunset District eye doctor knows that you are in good company if you wear contact lenses or glasses. Statistics show that over 160 million people in the United States alone wear corrective lenses and perfect vision is very rare.
