Glaucoma is a group of diseases that can damage the eye's optic nerve and result in vision loss and blindness. Glaucoma occurs when the normal fluid pressure inside the eyes slowly rises. However, with early treatment, you can often protect your eyes against serious vision loss.
Dry eye occurs when the eye does not produce tears properly, or when the tears are not of the correct consistency and evaporate too quickly. In addition, inflammation of the surface of the eye may occur along with dry eye. If left untreated, this condition can lead to pain, ulcers, or scars on the cornea, and some loss of vision. However, permanent loss of vision from dry eye is uncommon.
Dry eye can make it more difficult to perform some activities, such as using a computer or reading for an extended period of time, and it can decrease tolerance for dry environments, such as the air inside an airplane. Tears are composed of three major components: a) outer, oily, lipid layer produced by the meibomian glands; b) middle, watery, lacrimal layer produced by the lacrimal glands; and c) inner, mucous or mucin layer produced by goblet cells located within a thin transparent layer over the white part of the eye and covering the inner surface of the eyelids. Tears are made of proteins (including growth factors), electrolytes, and vitamins that are critical to maintain the health of the eye surface and to prevent infection.
Tears are constantly produced to bathe, nourish, and protect the eye surface. They are also produced in response to emergencies, such as a particle of dust in the eye, an infection or irritation of the eye, or an onset of strong emotions. When the lacrimal glands fail to produce sufficient tears, dry eye can result.
Any disease process that alters the components of tears can make them unhealthy and result in dry eye.

|Who Is Likely To Develop Dry Eye? (Common After Menopause)|
|Elderly people frequently experience dryness of the eyes, but dry eye can occur at any age. Dry eye is more common after menopause. Women who experience menopause prematurely are more likely to have eye surface damage from dry eye.|
|How Is Dry Eye Treated?(Treatment)|
Depending on the causes of dry eye, your doctor may use various approaches to relieve the symptoms. Cyclosporine, an anti-inflammatory medication, is the only prescription drug available to treat dry eye. It decreases corneal damage, increases basic tear production, and reduces symptoms of dry eye. It may take three to six months of twice-a-day dosages for the medication to work. In some cases of severe dry eye, short term use of corticosteroid eye drops that decrease inflammation is required.
To plug the drainage holes, small circular openings at the inner corners of the eyelids where tears drain from the eye into the nose. Lacrimal plugs, also called punctal plugs, can be inserted painlessly by an eye care professional. The patient usually does not feel them. These plugs are made of silicone or collagen, are reversible, and are a temporary measure. In severe cases, permanent plugs may be considered.
In some cases, a simple surgery, called punctal cautery, is recommended to permanently close the drainage holes. The procedure helps keep the limited volume of tears on the eye for a longer period of time. In some patients with dry eye, supplements or dietary sources (such as tuna fish) of omega-3 fatty acids (especially DHA and EPA) may decrease symptoms of irritation.
|What can I do to help myself?|
|Use artificial tears, gels, gel inserts, and ointments - available over the counter - as the first line of therapy. They offer temporary relief and provide an important replacement of naturally produced tears in patients with aqueous tear deficiency. Avoid artificial tears with preservatives if you need to apply them more than four times a day or preparations with chemicals that cause blood vessels to constrict.|
Wearing glasses or sunglasses that fit close to the face (wrap around shades) or that have side shields can help slow tear evaporation from the eye surfaces. Indoors, an air cleaner to filter dust and other particles helps prevent dry eyes. A humidifier also may help by adding moisture to the air.
Avoid dry conditions and allow your eyes to rest when performing activities that require you to use your eyes for long periods of time. Instill lubricating eye drops while performing these tasks.
|Computer Vision Syndrome (CVS) is a complex of eye and vision problems experienced when spending long hours in front of a computer screen. In this day and age, where students and working adults spend hours and hours on end in front of the computer screen, CVS is more common than you think.|
|What Are The Symptoms Of CVS?(Sign & Symptoms )|
The signs are clear. Headaches, burning or tired eyes, double vision or blurred vision, the loss of focus, general eye strain, dry eyes, light sensitivity, chronic neck and shoulder pains - all these problems point to the fact that you've been working far too many hours in front of the computer without a break.|
Another less common symptom is the slowness in the changing of focus of sight. This can be better explained by a slight delay in the eye's ability to bring the newer image into focus when quickly shifting the sight from something in the distance to something closer by, or vice versa. The overuse of the focusing muscles tires the eyes and eye strain is often accompanied by a dry or burning sensation.
|What Are The Symptoms Of CVS?(CVS Treatment And Relief )|
|To prevent or minimize Computer Vision Syndrome, take regular breaks from the computer monitor - once every 30 minutes thereabouts - and walk about periodically. Stare out the window at some lush greenery. If you're in the middle of an urban jungle, gaze at a green plant or soothing green object instead.|
