Final answer:
Cataract, glaucoma, and eye infections are common eye disorders that can cause vision problems. Cataracts are characterized by cloudiness in the lens of the eye and can be treated with surgery. Glaucoma damages the optic nerve and can lead to vision loss if left untreated. Eye infections, caused by bacteria or viruses, can cause inflammation and other symptoms.
Step-by-step explanation:
Cataract:
A cataract is a condition characterized by cloudiness in the lens of the eye. It can cause blurry vision, sensitivity to light, and difficulty seeing at night. The primary cause of cataracts is aging, but they can also be caused by genetics, certain medications, and eye injuries. Treatment for cataracts usually involves surgery to remove the cloudy lens and replace it with an artificial lens.
Glaucoma:
Glaucoma is a group of eye disorders that damage the optic nerve, leading to progressive vision loss. It is often associated with increased pressure in the eye. The most common type of glaucoma is called primary open-angle glaucoma. It usually has no noticeable symptoms in the early stages but can eventually cause peripheral vision loss and, if untreated, blindness. Treatment for glaucoma includes eye drops, oral medications, surgery, or laser therapy to lower eye pressure and prevent further damage to the optic nerve.
Eye Infection:
An eye infection refers to an inflammation or infection of the eye or its surrounding structures, such as the conjunctiva (conjunctivitis) or the cornea (keratitis). Eye infections can be caused by bacteria, viruses, or other microorganisms. Symptoms of an eye infection may include redness, itching, discharge, blurry vision, and sensitivity to light. Treatment for eye infections depends on the cause and may involve antibiotics, antiviral medications, or other topical treatments.
