Presbyopia
Presbyopia causes people's eyes to be unable to focus as
quickly on close-up objects. It naturally affects everyone's
eyes as they age.
Conjunctivitis (pink eye)
Conjunctivitis, or "pink eye," is an infection or swelling in
the eye area that causes inflammation of the conjunctiva,
giving the eye a red or pink color.
Allergic conjunctivitis
Allergic conjunctivitis is when exposure to allergens (such
as mold spores or pollen) cause your eyes to become
watery, red, and itchy.
