Contact Lens Over wear syndrome (OWS)....

by - 1/27/2013

Contact lenses are not meant to be worn 24 hours a day, if you wear contact lenses for too many hours of the day and fail to replace them regularly, you run the risk of contact lens complications.

Over-Wear Syndrome may occur if the contact lenses are worn beyond the appropriate time. OWS can also result from wearing lenses while sleeping or from neglecting to replace them at regular intervals. Contact lens over-wear syndrome is most common with non-gas permeable hard lenses and can be quite painful. In severe cases, it may lead to eye infections and other complications.

Causes Of Over-wear Syndrome.

When the eye is open, it receives oxygen directly from the atmosphere, when the eye is covered by a contact lens it receives oxygen from capillaries in the ocular region, which will provide a lesser amount than that of the atmosphere. Contact lens movement, thickness, oxygen permeability and wearing schedule all impact the amount of oxygen reaching your cornea. If you wear your lenses for too long, it will further reduce the amount of oxygen reaching your cornea, which may lead to complications.

Symptoms of Over-Wear Syndrome.

Here are some symptoms experienced by people suffering from OWS.

- Severe eye pain
- Redness of the eye
- Decreased vision
- Photo-phobia

Treatment of Over-Wear Syndrome.

If you notice you are suffering from OWS,
- You should stop wearing contact lens immediately.
- Some ophthalmologist may prescribe a tropical antibiotic therapy or tropical steroidal preparation to alleviate symptoms.
- Once the OWS subsides, you may resume wearing your contact lens.

If you have a feeling that you are experiencing anything that looks like Over-Wear syndrome, its advisable to contact an eye doctor for an appointment.
