Vision testing checks how well you can see. An eye doctor uses charts and tools to measure your clarity of vision, color vision, and side vision. These tests help find out if you need glasses or other treatment to keep your eyes healthy.
This measures the clarity or sharpness of vision, usually with a Snellen chart (the chart with rows of letters that get progressively smaller).
Determines if corrective lenses (glasses or contact lenses) are needed and what prescription is necessary to correct nearsightedness, farsightedness, or astigmatism.
Assesses the ability to distinguish between different colors, often to check for color blindness.
Checks the side vision to detect any vision loss that may indicate conditions like glaucoma.
Examines how well someone perceives the distance and depth of objects.
Evaluates how well the muscles around the eyes control eye movement.
