Blepharospasm is the medical term for abnormal involuntary contraction or twitching of the eyelid. Ptosis refers to drooping of the upper eyelid, conjunctivitis is inflammation of the conjunctiva, and glaucoma is a condition of increased pressure within the eyeball.

Epiphora refers to excessive tearing of the eye, usually due to an overflow of tears from the eyes' drainage system. Conjunctivitis is an inflammation of the outermost layer of the eye; Glaucoma is a group of eye conditions that damage the optic nerve; and Astigmatism is a common refractive error of the eye.

Entropion is a condition where the eyelid rolls inward, which can cause irritation and damage to the eye. Blepharitis is inflammation of the eyelids, ptosis is drooping of the upper eyelid, and nystagmus is involuntary eye movements.

When an STT strip is left in the eye for 1 min, it can lead to decreased tear production and dry eyes, which is a common symptom of keratoconjunctivitis sicca (KCS). Conjunctivitis is an inflammation of the conjunctiva, corneal ulcer is an open sore on the cornea, and uveitis is inflammation of the uvea, none of which are directly related to the presence of an STT strip.

The opacity in the eye is located in the lens, which can result in conditions like cataracts. The cornea is the clear front part of the eye, the retina is the light-sensitive layer at the back of the eye, and the iris is the colored part of the eye that controls the size of the pupil.
