If your eyes burn after removing  the lenses, it is probably because you have developed a mild keratitis, either from oxygen deprivation or a sensitivity to your solution.  The contact is acting as a bandage--that is why you are not aware of it while wearing the lenses.  In addition to being a clinical professor in the contact lens department of an Optometry school, I have also conducted studies on protein deposition in soft contacts lenses. The protein absorbed into the lens, and coating the lens, is negligible in terms of oxygen transmission through the lens.  Think about it: when soft lenses first came on the market, they were designed to be replaced once a year.  The lenses were much thicker, and had a lower oxygen transmission rate, but most people did just fine.. This was before chemical disinfectants, so the lenses were heat treated to disinfect them.  As time went by, the lenses became less comfortable because of the friction from a sticky lens, and people were more apt to develop an allergic type reaction to the denatured proteins on the lens (giant papillary conjunctivitis.) Try changing to a hydrogen peroxide based cleaning system or rinsing your lenses off well with non preserved saline before inserting them.

If your problem is due to an ill fitting lens, changing to a fresh lens will not solve the problem.  If your eyes feel better after day one of using a new pair, it is likely that your solution is the culprit, as the lenses come packed in preservative free saline.  RGP lenses have a much higher Dk value (oxygen transmission rate) than any soft lens.  In addition, every time your blink, you push oxygen rich tears under the lens.  Actually, a well fitting RGP lens is much healthier than a soft lens.  The original hard lenses were made of PMMA, which transmitted zero oxygen through the lens.  Most labs stopped making PMMA lenses years ago.  Solution sensitivity is very common and specific to the brand.

Expertise

I can answer almost any question about vision and general eye health care. As a non-surgeon, I may not be able to answer very involved technical questions about surgical procedures or highly specialized medical treatments. As of March 10, 2010, I will no longer answer any questions about Clear Care. People who do not understand how to use it should contact their eye doctor directly for advice.

Experience

I hold the degree of Doctor of Optometry and was in full-time private practice for twenty-five years. Currently I have reduced my schedule to part-time to allow time to write a book on another topic.
