Charts, Eye, Visual Acuity

Definition : Eye charts designed to be used in measuring visual acuity using a sheet of paper on which rows of standard symbols of different sizes are printed. The symbols can be shaped letters (e.g. block letters, letter E), numbers, or outlines of objects. Visual acuity is measured by the smallest row of symbols a person standing at a certain distance can identify (each row is marked with a distance value). Projectors or monitor screens indicating the ophthalmic symbols are also used for this purpose. Visual acuity eye charts are used mainly for vision screening in healthcare facilities, at ophthalmologist offices, and in the field.
