Contact Lens And Dry Eye Explained
A thin layer of tears covers the surface of normal, healthy eyes. This fluid lubricates and protects the surface.
There are several glands around the eyes that constantly replenish these tears, as they naturally evaporate or drain down and out the tear duct.
Dry Eye occurs when something interferes with the tears normal production or function, leaving your eyes unprotected.
Contact lenses wearers and allergy sufferers frequently suffer from Dry Eye Syndrome.
In mild cases of dry eye, a slight burning, scratchy or sandy sensation is common.
In moderate to severe dry eye, you might also experience frequent blinking, blurred vision, a sensitivity to light, and even reflex or excessive tearing.
The most common cause of dry eye is aging when the quantity and effectiveness of your tears decrease.
Anti-anxiety agents, Anti-histamines and oral contraceptive medications can also decrease tear production and cause dry eye.
Environmental factors such as exposure to wind, smog, dry air, smoke, prolonged work at a computer terminal may aggravate this condition.
The winter season with its cold, dry, windy weather may also increase irritation.
Others include low levels of humidity, air tight office buildings and environments where pollutants and dust are at a high level.
Remember contact lenses contain water so the eye can receive high levels of oxygen. They can also aggravate and make dry eye symptoms worse because...as contact lenses dehydrate they fit tighter. This can create a foreign body or loose eye lash sensation which comes from the edge of the contact lens. Depending on the edge design some contact lenses will feel better than others.
Drying is also quicker in areas where there are deposits and coatings. Please be sure to physically rub both sides of all contact lenses, even disposables, for at least 10 seconds during cleaning.
If your Dry Eye is environmentally related, avoiding those situations will help.
Tips For Dry Eye Contact Lens Wearers
Maintaining a more humid home or work environment with a humidifier.
Applying an ocular lubricant regularly such as artificial tears may help. There are many different kinds of eye drops available over the counter. Some of which should NOT be used with contact lenses so be sure the label states they are safe to use with ALL soft contact lenses.
If your Dry Eye is environmentally related, avoiding those situations will help.
Please consult your local eye care professional if you do not find relief from over the counter artificial tears, and please do NOT wear contact lenses if your eyes become red and more irritated while wearing them.
