An eye chart, such as a standard Snellen chart of progressively smaller letters, is then used to determine the person's visual acuity.

The leading reason for corneal tattooing is to alter the appearance of the eye cosmetically. Usually, the need for this alteration stems from corneal opacity.Corneal opacities (scarring of the cornea that creates an opaque or semi-transparent area on the eye) may be caused by leucoma, keratitis or cataracts.
