Visual acuity is the eye's ability to detect fine details and is the quantitative measure of the eye's ability to see an in-focus image at a certain distance. The only time we even have caused to think about our vision as such is when we think about a blind person who has no vision at all, or our own vision begins to fail us. An examination of papillary function includes inspecting the pupils for equal size, regular shape, reactivity to light, and direct and consensual accommodation.
If you have health or eye care insurance, make sure your doctor accepts your specific plan. Also, bring your insurance card with you to the exam to make sure the billing process goes smoothly. Because the doctor will perform many tests to analyze your ability to focus, he can achieve more accurate results if you are fresh and alert. People with certain eye diseases are not able to enjoy these experiences to their full extent and sometimes not at all. Those who are outside most of the day should use protective sunglasses or eyeglasses to prevent heavy exposure to ultraviolet light. Eye Care is a serious concern that is often neglected by people who lack health insurance.
