Vision Letter Chart

Vision Letter Chart - Visual acuity depends on optical and neural factors. As a result, your vision becomes blurred. Vision is the special sense of sight that is based on the transduction of light stimuli received through the eyes. A cataract scatters and blocks the light as it passes through the lens. The eyes are located within either orbit in the skull. Eyeglasses or contacts help you have 20/20 vision. But what does that really mean? This prevents a sharply defined image from reaching your retina. Visual acuity scores are usually written as a fraction. Visual acuity is the ability of your eyes to see objects clearly, without any visual aids, from 20 feet away.
