Although we wear contact lenses to aid us in achieving good vision, it is still considered a foreign body which has the full potential to give rise to several eye problems such as infections. These complications, although fairly rare, can be prevented easily when treated early. The incidence of these complications increases due to failure to comply with stringent lens hygiene and inappropriate lens wearing schedules.
The cornea is a clear, thin tissue that covering the pupil and iris. To maintain a healthy cornea, constant supply of oxygen is very crucial. With the use of contact lenses, the oxygen supply for the cornea is diminished and because of this complications can arise.
When contacts are worn for longer periods of time, very little oxygen reaches the cornea. Red eyes, blurry vision, eye pain and photosensitivity indicated oxygen depletion. To avoid this complication, it would be best to strictly follow the schedule of recommended replacement of contact lenses that is being worn. When these symptoms occur, remove the contact lenses as soon as possible and notify your eye doctor.
The giant papillary conjunctivitis or GPC is a type of allergic disorder that is very common among people who wear soft contact lenses. When contacts are worn for too long without being cleaned properly, protein deposits begin to pile up in the lens which leads to an allergic response when applied back to the eye. Symptoms of GPC include itchiness, redness, and increased movement of contacts in the eyes. Once these symptoms occur, remove the contacts from the eyes, followed by consultation to an eye doctor.
Another complication called corneal vascularization results from prolonged use of contacts causing very tiny blood vessels to appear in the cornea's clear tissue as oxygen supply is continues to diminish. The wearer may complain of cloudy and blurred vision. When this happens, it is much safer to discontinue the use of contacts and consult an eye doctor to determine the exact cause of this condition.
Since not all of us are great candidates for contact lenses, it would be best to first contact your eye doctor Austin to determine your suitability for wearing contacts.
