Eye disorders also known as eye conditions or ophthalmic disorders, encompass a wide range of medical conditions that affect the eyes and visual system. These disorders can vary in severity and may lead to vision problems or even permanent vision loss if left untreated. 

Here's a brief overview of some common eye disorders:

Refractive Errors: Refractive errors are the most common eye disorders and include conditions like myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related loss of near vision). These disorders occur when the shape of the eye or the cornea prevents light from focusing properly on the retina, leading to blurred vision.

Cataracts: Cataracts are characterized by the clouding of the eye's natural lens, leading to decreased vision, glare sensitivity, and difficulty seeing in low light conditions. Cataracts commonly occur due to aging, but they can also develop as a result of injury or other underlying medical conditions.

Glaucoma: Glaucoma is a group of eye diseases that damage the optic nerve, often due to increased intraocular pressure (pressure inside the eye). If left untreated, glaucoma can lead to permanent vision loss and even blindness.

Diabetic Retinopathy: This eye disorder occurs in people with diabetes and is caused by damage to the blood vessels in the retina. Diabetic retinopathy can lead to vision loss and blindness if not managed properly.

Dry Eye Syndrome: Dry eye occurs when the eyes do not produce enough tears or the tears evaporate too quickly. It can lead to discomfort, redness, and blurred vision.

Conjunctivitis: Also known as pink eye, conjunctivitis is the inflammation of the conjunctiva, the thin, transparent layer covering the white part of the eye and the inner surface of the eyelids. It can be caused by viruses, bacteria, allergies, or irritants.

Strabismus: Strabismus is a condition where the eyes are misaligned and do not point in the same direction. It can lead to amblyopia (lazy eye) if not treated early in life.
