Eye CareWhat is the structure of the eye?The eyes are complex sensory organs. About 85% of the total sensory input to our brains originates from our sense of sight, while the other 15% comes from the other four senses of hearing, smell, touch, and taste. The eyes are designed to optimize vision under conditions of varying light. Their location, on the outside of the face, makes them susceptible to trauma, environmental chemicals and particles, and infectious agents. The eyelids and the position of the eye within the bony orbital cavity are the major protective mechanism for the eye. The eye itself has the shape of a sphere measuring about 1 inch in diameter. It consists of a clear, transparent dome at the front (the cornea) that is surrounded by the white of the eyeball (the sclera). The iris of the eye is the circular, colored portion within the eye, and behind the cornea, and the pupil is the central opening within the iris. Behind the iris and pupil is the eye's lens. The space behind the back of the cornea and the front of the lens is called the anterior chamber and is filled with the aqueous fluid. Behind the lens is a large space that is filled by the transparent vitreous gel. The inside of the back of the eye is lined by the retina, the thin, light-sensitive tissue that changes light images to electrical signals via a chemical reaction. These electrical signals generated by the retina are sent to our brain through the optic nerve. Our brain interprets what our eyes see. The inner sides of the eyelids, which touch the front surface of surface of the eye, are covered by a thin membrane (the palpebral conjunctiva) that produces mucus to lubricate the eye. This thin membrane folds back on itself and covers the visible sclera of the eyeball. (This continuation of the palpebral conjunctiva is called the bulbar conjunctiva.) Natural oil for the tears is produced by tiny glands located at the edges of the eyelids, providing add... Recommended Reading Related to Eye CareWhat is a visual field test?A visual field test is a method of measuring an individual's entire scope of vision, that is their central and peripheral (side) vision. Visual field testing actually maps the visual fields of each eye individually. The visual field test is a subjective examination, requiring the patient to understand the testing instructions, fully cooperate, and complete the entire test in order to provide useful information. What is a visual field test used for?Visual field testing is most frequently used to detect any signs of glaucoma damage to the optic nerve. In addition, visual field tests are useful for detection of central or peripheral retinal disease, eyelid conditions such as ptosis or drooping, optic nerve disease, and diseases affecting the visual pathways within the brain. The visual pathways carry information from the eye to the visual or occipital cortex in the brain, where this information is proces... Other Related Eye Care ArticlesEmergency Contact for Corona

Sty (Stye)
- A sty (sometimes spelled stye) is a tender, painful red bump located at the base of an eyelash or on, inside, or under the eyelid, which is the result of an acute infection of the oil glands of the eyelid. Complications of a sty can be blepharitis and chalazion.
-
Pink Eye
- Pink eye, also called conjunctivitis, is redness or irritation of the conjunctivae, the membranes on the inner part of the eyelids and the membranes covering the whites of the eyes. These membranes react to a wide range of bacteria, viruses, allergy-provoking agents, irritants, and toxic agents.
-
Sjogren's Syndrome
- Sjögren's syndrome is an autoimmune disease involving the abnormal production of extra antibodies that attack the glands and connective tissue. Sjögren's syndrome with gland inflammation (resulting dry eyes and mouth, etc.) that is not associated with another connective tissue disease is referred to as primary Sjögren's syndrome. Sjögren's syndrome that is also associated with a connective tissue disease, such as rheumatoid arthritis, systemic lupus erythematosus, or scleroderma, is referred to as secondary Sjögren's syndrome. Though there is no cure for Sjögren's syndrome, the symptoms may be treated by using lubricating eye ointments, drinking plenty of water, humidifying the air, and using glycerin swabs. Medications are also available to treat dry eye and dry mouth.
-
Retinal Detachment
- Retinal detachment is the separation of the retina from its attachments to the underlying eye tissue. Symptoms of retinal detachment include flashing lights and floaters. Highly nearsighted young adults and those who've had cataract surgery are at higher risk for retinal detachment.
-
Glaucoma
- Glaucoma is a common eye condition in which the fluid pressure inside the eye rises because of slowed fluid drainage from the eye. If untreated, glaucoma may damage the optic nerve and other parts of the eye, causing the loss of vision or even blindness.
-
Floaters
- Eye floaters are deposits or condensation that forms in the eye's vitreous humor. These deposits cast shadows on the retina, and as the eye moves, the deposits shift position, making it appear as though the shadows are moving or floating.
-
Dry Eyes
- Dry eyes are caused by an imbalance in the tear-flow system of the eye, but also can be caused by the drying out of the tear film. This can be due to dry air created by air conditioning, heat, or other environmental conditions. Treatment may involve self-care measures, medications, or rarely, surgery.
-
Subconjunctival Hemorrhage
- A subconjunctival hemorrhage is bleeding under the eye's conjunctiva. There is usually no obvious cause for a subconjunctival hemorrhage, but it may be caused by sneezing, vomiting, infections on the outside of the eye, coughing, and clotting disorders. Symptoms and signs include blood in the white of the eye and a sense of fullness under the lid. No treatment is needed.
-
Cataracts
- A cataract is an eye disease that causes the eye's lens to become cloudy and opaque with decreased vision. Causes of cataracts include diabetes, hypothyroidism, certain genetic illnesses, hyperparathyroidism, atopic dermatitis, and certain medications. Symptoms and signs include a decrease in vision and a whitish color to the affected eye. Treatment depends upon the patient's specific visual needs and may involve cataract surgery.
-
Eye Strain
- Eye strain is a symptom caused by looking at something for a long time. Symptoms and signs include redness, light sensitivity, headaches, and blurred vision. Symptoms may be treated by closing the eyes and taking a break from the visual task.
-
Blepharitis
- Blepharitis is inflammation of the eyelids. Acne rosacea, Staphylococcal bacteria, allergies, sensitivities to makeup or contact lens solutions, head lice, or other conditions may cause blepharitis. Symptoms and signs include itchy eyelids, burning sensation in the eyes, crusting of the eyelids, light sensitivity, red, swollen eyelids, loss of eyelashes, and dandruff of the lashes and eyebrows. Proper eyelid hygiene and a regular cleaning routine controls blepharitis.
-
Uveitis
- Uveitis is inflammation of the eye. Symptoms include blurred vision, eye pain, eye redness, and floating spots before the eyes. Treatment may involve prescription eyedrops, antibiotics, and wearing dark glasses.
-
Blindness
- Blindness is the state of being sightless. Causes of blindness include macular degeneration, stroke, cataract, glaucoma, infection and trauma. Symptoms and signs may include eye pain, eye discharge, or the cornea or pupil turning white. Treatment of blindness depends upon the cause of the blindness.
-
Astigmatism
- Astigmatism is a common eye condition that's easily corrected by eyeglasses, contact lenses, or surgery. Symptoms of astigmatism are headaches, fatigue, eyestrain and blurred vision.
-
Diabetes and Eye Problems
- Diabetes and eye problems are generally caused by high blood sugar levels over an extended period of time. Types of eye problems in a person with diabetes include glaucoma, cataracts, and retinopathy. Examples of symptoms include blurred vision, headaches, eye aches, pain, halos around lights, loss of vision, watering eyes. Treatment for eye problems in people with diabetes depend on the type of eye problem. Prevention of eye problems include reducing blood pressure, cholesterol levels, quitting smoking, and maintaining proper blood glucose levels.
-
Double Vision
- Double vision (diplopia) is a symptom that my indicate Graves' disease, myasthenia gravis, stroke, multiple sclerosis, Guillain-Barre syndrome, diabetes, cataracts, aneurysm, brain tumor, or migraine. Symptoms and signs include eye pain, droopy eyelids, nausea, headache, and a cross-eyed appearance. Treatment of double vision depends upon the underlying cause.
-
Black Eye
- The most common cause of a black eye is due to an injury to the face or head. Most black eye injuries are minor and heal on their own, however, some may lead to significant injury. In addition to trauma to the face, cosmetic surgery can cause a black eye(s) as a side effect. People should be aware of the situations in which medical care should be sought immediately for a black eye.
-
Macular Degeneration
- Age-related macular degeneration (AMD) is a disease that gradually destroys the central vision. In people over 60, AMD is a leading cause of vision loss. Wet AMD occurs when abnormal blood vessels behind the retina start to grow under the macula, leaking blood and fluid and causing rapid vision loss. In dry AMD, light-sensitive cells slowly break down in the macula, resulting in gradual vision loss. Pain is not associated with either form of AMD.
-
Myopia
- Myopia, or nearsightedness, makes it difficult to focus on objects that are far away. The condition runs in families and occurs because light focuses in front of the retina, instead of directly on it. Headaches, eye strain, and fatigue are symptoms of myopia. The condition is diagnosed by having an eye exam and can be treated by wearing glasses or contact lenses or by having refractive surgery.
-
Coats' Disease
- eye. Read about symptoms, signs, diagnosis, treatment, and prognosis. Coats' disease is a rare eye condition that typically progresses to vision loss or blindness in one eye. Gradual vision loss is usually the first symptom, followed by a cloudy white or yellow pupil due to the presence of a cataract. Treatment focuses on limiting the blood vessel progression and may involve cryotherapy or laser photocoagulation.
-
Keratoconus
- Keratoconus is a condition in which the cornea bulges outward like a cone. The cause of the condition is unknown, but genetics may play a role. Changes in the shape of the cornea make it difficult for the eyes to focus. Keratoconus is diagnosed by having an eye exam. Treatment involves wearing glasses or contact lenses.
-
Contact Lenses: Colored, Soft, Hard, Toric and Bifocal
- Contact lenses fit over the cornea and correct vision problems such as nearsightedness, farsightedness, or astigmatism. Contact lenses may be hard or soft. Bifocal contact lenses may be worn by those who have presbyopia. Toric contact lenses are for people who have astigmatism.
-
Eyeglasses, Sunglasses, and Magnifying Glasses
- Nonprescription eyeglasses are available over the counter (OTC) and are typically used by people who can no longer read fine print. OTC trifocals are helpful for those who require multiple distances or focal lengths for near and intermediate tasks. OTC sunglasses should offer 100% protection from the sun's UVA and UVB rays. OTC magnifying glasses are useful for viewing tiny objects or fine print.
-
Strabismus (Crossed Eyes)
- Strabismus, or crossed eyes, is a condition in which the eyes do not align in the usual way. The condition may be congenital or the result of a problem with the control of the muscles of the eyes. Strabismus may cause double vision, headaches, eyestrain, and problems with depth perception and peripheral vision. Treatment may involve physical therapy, vision therapy, surgery, or wearing glasses.
-
Farsightedness
- Farsightedness makes it difficult to focus on objects that are close up. The condition runs in families and occurs because light focuses behind the retina, instead of directly on it. Headaches, eye strain, and fatigue are symptoms of farsightedness. The condition is diagnosed by having an eye exam and can be treated by wearing glasses or contact lenses or by having refractive surgery.
-
Presbyopia
- Presbyopia is the age-related loss of the ability to focus on objects that are close up. The condition generally affects people over 45 years of age and causes blurred vision, headaches, and the need to hold reading material at arm's length. Presbyopia cannot be cured. Prescription contact lenses and glasses can help those who have presbyopia to see more clearly.
