Persistent dryness, scratchiness and a burning sensation in your eyes are symptoms of dry eyes. These symptoms alone may prompt your eye doctor to diagnose a dry eye syndrome.Dry eyes can become red and irritated, causing a feeling of scratchiness. But sometimes your eye doctor may want to measure the amount of tears in your eyes. Another symptom of dry eyes is a "foreign body sensation," the feeling that something is in the eye. It may seem odd, but dry eye syndrome can cause watery eyes. This is because dryness on the eye's surface sometimes overstimulate production of the watery component of your tears as a protective mechanism.
- In dry eye syndrome, the lacrimal gland or associated glands near the eye don't produce enough tears, or the tears have a chemical composition that causes them to evaporate too quickly.
- Dry eye syndrome has several causes. It occurs as a part of the natural aging process, especially during menopause; as a side effect of many medications, such as antihistamines, antidepressants, certain blood pressure medicines, Parkinson's medications and birth control pills; or because you live in a dry, dusty or windy climate.
- If your home or office has air conditioning or a dry heating system, that too can dry out your eyes. Another cause is insufficient blinking, such as when you're staring at a computer screen all day.
- Dry eyes are also a symptom of systemic diseases such as lupus, rheumatoid arthritis, ocular rosacea or Sjogren's syndrome (a triad of dry eyes, dry mouth and rheumatoid arthritis or lupus). Long-term contact lens wear is another cause.
- Recent research indicates that contact lens wear and dry eyes can be a vicious cycle. Dry eye syndrome makes contact lenses feel uncomfortable, and evaporation of moisture from contact lenses worsens dry eye symptoms. Incomplete closure of the eyelids, eyelid disease and a deficiency of the tear-producing glands are other causes.
- Recent research suggests that smoking, too, can increase your risk of dry eye syndrome..
- With increased popularity of cosmetic eyelid surgery (blepharoplasty) for improved appearance, dry eye complaints now occasionally are associated with incomplete closure of eyelids following such a procedure.
Many people suffer with dry eyes and the only relief they get is by using eye drops which temperorily relieves them and they continue for years together with the drops.Homeopathy does have a solution to the problem. Taking medicines over a period of time helps in increasing the production of tears which in turn reduces the dryness of the eyes
