hyperopia - A refractive abnormality of the eye requiring a plus (positive or convex) lens for correction. Synonyms: far sighted, hypermetropia. Far or distance sighted people can see at a distance more clearly than they can see objects which are closer.
immune system - The body's internal defense system which defends you from dangers such as infections, cancer, etc. Normal healing is coordinated with the immune system. Occasionally abnormal immunity can cause problems such as iritis or arthritis. These conditiions are referred to as auto-immune conditions meaning your immune system becoming confused and attacking your body.

Sclera - (SKLEH-ruh) The white outer layer of the eye, which is tough and protective. It joins smoothly with the cornea and continues in the back of the eye, connecting with the sheath that covers the optic nerve.

Scotopic Pupil Size - The size of the pupil in dim lighting conditions, as in moonlight.

: Accommodation - The eye’s ability to switch focus from near objects to far objects. It’s done by tiny muscles attached to the eye’s lens, which pull on the lens to change its convexity. As we age, those muscles become weaker and the lens becomes stiffer, a condition known as presbyopia, where reading glasses become necessary to see close-up objects.

Acuity - (a-KEW-uh-tee) Clarity or sharpness of vision, commonly expressed as 20/20 vision in relation to the Snellen acuity chart. This is the eye chart seen at every eye doctor’s office, with the big E at the top.
