Some of the common eye problems include Color Blindness, Blepharitis, Macular Degeneration, Glaucoma, Astigmatism, Strabismus, Cataracts, Myopia, Low Vision, Blindness, Presbyopia, and Eye Infection/Conjunctivitis/Pinkeye
Color blindness or color vision deficiency is the inability to perceive differences between some of the colors. It usually occurs because of eye, nerve, or brain damage, or exposure to certain chemicals. Color vision deficiencies can be classified as: Monochromacy, also known as total color blindness, is the lack of ability to distinguish colors; caused by cone defect or absence. Dichromacy is a moderately severe color vision defect in which one of the three basic color mechanisms is absent or not functioning. It is hereditary. Anomalous trichromacy is a common type of inherited color vision deficiency, occurring when one of the three cone pigments is altered in its spectral sensitivity.
Blepharitis is a chronic inflammation of the eyelid. Blepharitis may be caused by inflammation, bacteria, allergies, tumors, environmental conditions, or it may be related to systemic disease. Blepharitis usually causes symptoms of eye itching, irritation, burning, and the sensation that something is present in the eye.
Glaucoma is a disease of the optic nerve. The optic nerve receives light from the retina and transmits impulses to the brain that we perceive as vision. Glaucoma is usually associated with elevated pressure in the eye that leads to damage of the eye nerve. Elevated pressure in the eye is the main factor leading to glaucomatous damage to the eye nerve. There are two main types of glaucoma: Open-angle glaucoma and Closed-angle glaucoma. Open-angle Glaucoma is painless and does not have acute attacks. Closed-angle Glaucoma is characterized by sudden ocular pain, seeing halos around lights, red eye, nausea and vomiting, sudden decreased vision.
Cataracts are changes in clarity of the natural lens inside the eye that degrades visual quality. Cataracts are classified as one of three types. A subcapsular cataract begins at the back of the lens. A nuclear cataract forms in the nucleus, the center of the lens, and is due to natural aging changes. A cortical cataract forms in the lens cortex.
Conjunctivitis is the inflammation of the conjunctiva i.e. the membrane that lines the eyelids and covers the exposed surface of the eyeball. It can be caused by allergies, bacteria, viruses, chemicals, or underlying health conditions.Conjunctivitis can be classified as infectious or noninfectious. Infectious conjunctivitis or pinkeye is caused by either a bacteria or a virus. It is very contagious. Noninfectious conjunctivitis is caused by allergies (such as pollen or grass), or chemicals (such as air pollutants, smoke or household cleaners).
