Using chemical cleaners and transmitting lenses off for the special factory washing were common methods.

Lenses were often used for 3 to be able to 4 years right up until they were yellowed and covered along with numerous deposits coming from components of the particular tear film. Lipid bumps, calcium and even mineral deposits, protein deposits and frequent tears and little missing chunks of the lens edges had been tolerated well prior the healthy threshold of the eyes. A fresh eye issue commence to show up in a number of the patients of these new soft contact lens.

As lens technologies progressed and rates came down contacts were replaced more frequently and typically the mystery red eye syndrome seemed to drop off.
