Contact lenses and dry eyes. Causes, symptoms and treatments.

Contact lenses and dry eyes are usually only temporary and can time and again be minimized or eliminated by changing lens materials. Contact lens dry eyes can also be caused by wearing contact lense.

Causes of dry eyes

Dry eye syndrome (Keratoconjunctivitis sicca, also called keratitis sicca, sicca syndrome, xerophthalmia) or dry eyes is an eye disease caused by a lack of tear production and moisture which in turn decreases lubrication. Tears are vital to keep the eye moist and for general good eye health. If these tears are deficient or abnormal you may suffer from dry eyes when wearing contacts. There are many reason why your tears may be deficient or abnormal, some of the most common are;

• Your contact lenses  - eye contacts materials may absorb too much moisture. Cheap contact lenses can also cause discomfort
• Environment – can cause dehydration of the eye. Air conditioning, cigarette smoke or a dry dusy environment are common culprits
• Age – As we get older our tear production decreases. Hormone changes in women going through the menopause can also decrease tear production
• Medicine – side-effects of some prescribed medication such as antihistamines
• Illness – for example rheumatoid arthritis can cause dry eyes
• Damage – eye injury can cause problems with blinking which can impair the natural production of tears

Symptoms of dry eye syndrome

Both eyes usually are affected and sufferers usually report dryness, burning and a gritty eye irritation that gets worse as the day goes on. Some may report a pressure behind the eye, redness and pain. If the eye surface is damaged by dry eyes, there may also be a sensitivity to bright light.

Treatments for dry eyes

Dry eye syndrome can not always be cured. Rubbing of the eyes will irritate them more and should be avoided. Routinely blinking more often and resting the eyes are basic steps one can adopt. If the environment is the case, then avoiding dry or dusty conditions could help.

Additional lubrication is the most important part of treatment for mild and moderate cases.  Opticians possibly will prescribe artificial tears, lubricating eye drops that may lessen the dry, itchy-scratchy feeling and provide temporary relief.

You should not wear contact lenses whilst using eye ointment or eye drops. There are some drops available contact lens wearers that do not contain the preservative that can cause problems. Always take advice from an optician or doctor.
