- A friend recently learned from an optometrist that some veins have appeared
- on the periphery of one of her corneas. The cause was reduced oxygen to
- the cornea due to contact lenses. She has daily wear, gas permeable lenses
- (which she now wears 16 hours a day, 7 days a week), but apparently the
- oxygen permeability of gas permeable lenses can be as low as 14%.
-
- The optometrist felt that she can continue to wear contacts, but should
- give her eyes a rest by using glasses more often. He felt that the
- increase in oxygen could cause the veins to recede. Even after receding,
- however, he thought they might leave thin, white lines on the cornea.
-
- Any opinions on this matter and the accuracy of the optometrist's
- information?
-
- Thanks.
