Service Providers for Vision Test
A vision test is a procedure used to assess the clarity and sharpness of a person's vision, as well as to identify potential eye conditions. It typically involves reading letters or symbols from a chart (Snellen chart) at a set distance to evaluate visual acuity. Additional tests may include checking for color blindness, depth perception, and peripheral vision. For certain conditions, eye pressure or retinal health may be assessed. Preparation is usually minimal, but it’s recommended to bring corrective lenses if worn. The results help diagnose conditions like refractive errors, cataracts, or glaucoma, guiding treatment and corrective measures like glasses or surgery.
