What are the most common types of vision tests?

Conventional vision tests include color vision tests, refractive tests, visual acuity tests and visual field tests. All of these tests can be administered during routine eye tests and some are performed during regular physics to check your vision changes in the patient and determine if the recommendations for the vision specialist are required. These tests are repeated regularly to identify vision problems in time to be treated before the development of complications. This can be done for a number of reasons, from fear of inheritance of visual defects to worries about changing the optical nerve that could disrupt color vision. A common example is a set of cards covered with dots of different colors. The numbers and letters are built into dots and will be visible or invisible, depending on the ability of someone's vision.

refractive tests require dilation eyes, using the eye. The doctor looks into the eyes with light light to see the light behaves inside the eye, and the patient will also be asked to see a number of lenses to see if it isThe need for vision correction and finds out what level of correction is required. After this test, the patient will have to wear protective glasses before it comes out because there is a risk of eye damage caused by bright light when pupils are widespread.

visual acuity tests include seeing how well people can distinguish objects such as letters or numbers at different distances. The classic form is an eye chart on the wall where people are asked to read the chart and be marked from the last readable letters for the patient. People who are unable to read can be administered tests of visual acuity including identifying shapes and objects on a graph or card, allowing doctors to diagnose Vision problems in young children. Other visual tests include options like AMSLER grid used to control macular degeneration.

In tests in the field of view, the goal is to find out how much peripheral vision is for the patient to DSposition. Doctors can simply perform this test by standing in front of the patient and moving the target like a finger from left to right. The patient reports when the finger is no longer visible and the doctor may notice the point where he moved from the patient's field of vision. Peripheral vision changes identified during vision tests may be a sign of eye damage or surrounding structures.
