Actually it really is called an edge!
its called a face an edge is called en edge a point is called a vertex
Lateral inversion is the reversal of an object when the image is formed in a flat mirror. This reversal is only in the direction perpendicular to the surface of the mirror. However, the effect is often seen by a person as a "left-right" reversal with the "front-back" reversal not noticed. That's the reason it's called lateral inversion. "Lateral" means sideways.
A piece of an edge of a circle is called an ARC.
The diameter.
The condition you are referring to is called ectropion. It is when the edge of the eyelid turns outward, causing the inner eyelid surface to be exposed. This can lead to symptoms like tearing, redness, and irritation.
The fringe of hair that edges the eyelid; -- usually in the pl., A hair of the fringe on the edge of the eyelid.
The medical term for turning inward of the edge of an eyelid is "entropion." This condition can cause discomfort, irritation, and potential damage to the cornea due to the eyelashes rubbing against it. Treatment may involve surgery to correct the positioning of the eyelid.
A sty is also called a hordeolum. It is a red, painful lump near the edge of the eyelid resulting from an infection of a hair follicle or oil gland.
The third eyelid on a frog is called a nictitating membrane.
Hordeolum, commonly known as a stye, is a red, painful lump near the edge of the eyelid. It is usually caused by a bacterial infection in the oil glands of the eyelid. Warm compresses and good hygiene can help in its treatment.
A hut for a pig is called a sty, pigsty or pigpen. The plural of sty is sties.(Stye is a completely different word referring to a small infection at the edge of the eyelid.)
The feline second eyelid is called the third eyelid or nictitating membrane. It is a thin, protective covering that moves across the eye horizontally to help protect and moisten the eye.
Styes and chalazia are lumps in or along the edge of an eyelid. They may be painful or annoying, but they are rarely serious. Most will go away on their own without treatment. A stye is an infection that causes a tender red lump on the eyelid. Most styes occur along the edge of the eyelid. When a stye occurs inside the eyelid, it is called an internal hordeolum A chalazion (say "kuh-LAY-zee-on") is a lump in the eyelid. Chalazia (plural) may look like styes, but they are usually larger and may not be painful. Styes and chalazia may be related to blepharitis, a common problem that causes inflammation of the eyelids.
It is called "Lateral Inversion". Lateral means "sideways". The term is used because the image often seems left-right reversed. In fact the inversion is really at right angles to the mirror surface, but it can appear to be laterally reversed.
