Guide To The Different Eye Tests

Other than when asleep, eyesight is an integral part of nearly every activity individuals engage in on a day-to-day basis. Surfing the internet, driving, reading, and watching television all involve vision. Thus, protecting eye health is important to daily life. The best way for individuals to protect their eye health is to have regular eye exams with an optometrist. There are several eye tests an optometrist will use when assessing the health of a patient’s eyes. If they think a patient may have an eye disease that can’t be corrected with glasses, they may refer them to an ophthalmologist, an expert who specializes in eyes and eye diseases.

Knowing what to expect from different eye tests can help patients prepare for their appointment.

The test for visual acuity is the best-known test performed by an eye doctor. During this test, a sign is positioned at a specified distance. Patients will cover one eye at a time and read the sign. The optometrist measures the responses to determine how the level of vision in each eye compares to 20/20 vision. An individual with 20/20 vision can see details at twenty feet an average functional eye can. There aren’t any risks to a visual acuity test, and they’re a standard part of eye exams. For children, visual acuity tests are often a routine part of yearly physicals. This helps the pediatrician determine whether the child’s eye is developing correctly. In addition to undergoing this test at the eye doctor’s office, patients will likely undergo it at the driver’s licensing bureau to prove they can see well enough to drive. There are two main types of visual acuity test. A Snellen test is the best known and uses a chart of symbols or letters. A Random E test shows patients the letter E, and they have to determine which way it’s pointing.
