Choose Soft Contact Lenses For More Oxygen
November 22nd, 2007 | by admin |“People who have not had cataracts removed seem to need more oxygen,” said Dr. George Spocrl, an Arlington Heights ophthalmologist. “The bottom line is that the studies have shown that anyone who wears extended contact lenses is obviously compromising the amount of oxygen to the eye.”
The amount of oxygen that reaches the eye, and the carbon dioxide that leaves it, are the key to the success of any contact lens especially continuous-wear lenses.
Hard lenses, which are impermeable can cause damage to the cornea if worn for too many hours, especially during sleep. A soft contact lens, which can usually be worn longer than a hard one, has a higher water content and oxygen permeability.
