The eye works in much the same way that a camera does; light travels through the pupil (aperture) and the lens (camera lens) and falls on the retina (the film). The retina sends electrical signals via the optic nerve to the brain, where the actual image that we see is created. The exact center of the retina (macula) is the point where vision is the sharpest. The choroid, the peripheral area of the retina, enables spatial orientation. Finally, to bring an image into focus, whereas a camera uses a zoom, your ciliary muscles and lens perform the same function.
WHY IS IT EASIER FOR ME TO READ WHEN THE TYPE IS BIGGER? The visual process functions optimally in a young eye, assuming there are no inherited visual defects. As people grow older, their eyes change; the ciliary muscle weakens, the lens becomes slightly cloudy, and the retina becomes somewhat porous. It is completely normal for vision to deteriorate with age. It becomes noticeable after about age 45. People also require more light to see properly as they grow older. For example, a 60 year-old requires 15 times more light than a 10 year-old to perceive the same subjective brightness.
Change the way you SEE THE WORLD. Adequate light and the right print size make a major difference in how you see things. We offer a variety of products (Eschenbach) to augment your vision while shopping, working at home, or driving. And what about those fun evenings and weekends at home? Our optical systems will make it all the more enjoyable to curl up with a good book or watch television. CALL TODAY AND SCHEDULE AN APPOINTMENT FOR A LOW VISON EVALUATION.
