Explanation:

A Snellen chart is a standard tool for evaluating distance vision. It consists of letters or symbols of varying sizes. The patient reads the chart from a specific distance (usually 20 feet in the US), and the smallest line they can read accurately determines their visual acuity.

Glaucoma is a group of eye diseases that damage the optic nerve. One of the main risk factors and causes in many cases is increased intraocular pressure. The elevated pressure can gradually damage the optic nerve, leading to vision loss if not treated.
