Frequently Asked Questions and Answers About the Care of Your Vision
|
 | | |
| | | | Why are pupils dilated during an eye examination? | The pupil is the black hole in the very center of the colored part of the eye. The colored part of the eye is called the iris which is a small muscle surrounds the edge of the pupil. When the muscle contracts, the pupil becomes smaller. When the muscle relaxes, the pupil becomes large. The word “dilate” describes the pupil when it is large. So, when the pupils are dilated, it means the pupils are very large.

| | What is recommended if I am very nearsighted? | If you are nearsighted, you have a problem seeing clearly in the distance.
If you are extremely nearsighted, your glasses will have thick-edged lenses. To minimize this edge thickness, you may consider a “high index” lens material (a material similar to plastic that provides a thinner edge with the same power). A wise frame choice would be a small, rounded shape to keep the edges as thin as possible. For the best look, the distance
between your eyes should be approximately equal to the distance
between the centers of the frame that you choose.

| | How do work and my lifestyle affect my eyewear choices? | The kinds of vocational or leisure demands you place upon your eyes impacts your eyewear choices. Glasses need to match your needs and the environments in which they will be worn. For example, factory workers will need glasses, which are impact resistant to protect their eyes from flying objects.

| | What is recommended if I am extremely farsighted? | If you are farsighted, you will have a problem seeing close up. If you are extremely far- sighted, your lenses will be thick in the centers and will
magnify your eyes. To counteract these problems, “aspheric” lenses
(lenses with a computer generated front curvature, which reduces magnification and thickness) were designed. When choosing a frame,
avoid rimless ones because they will have very thin edges and will be too fragile to hold the lenses properly.

| | How do you weigh quality with the cost of eyeglasses? | If you wear your glasses all day and every day, then you need a high quality pair of glasses. High quality frames and lenses are a good investment. Spring-loaded hinges, silicon rubber nose pads, and high quality materials are all features of a good frame. Many times, when your prescription changes, you can have new lenses cut to fit your original frame if it has remained in good condition. This is when a high quality frame investment really pays off.
If you wear your glasses occasionally or lose them frequently, then a less costly pair of spectacles would be a good idea. Also, if your prescription changes very frequently, you would not want to spend much on your lenses. In eyewear today, there is a wide variety of pricing; however, the old saying holds true that, “You get what you
pay for.”
