Because silicone hydrogel lenses with high oxygen transmissibility are different from the conventional hydrogel ones, our cornea requires 2 to 3 days to adapt to this new material when wearing the silicone hydrogel lenses for the first time. Very few people (about 1%) may experience some symptoms during the first four days like redness, feeling of foreign objects in their eyes and the secretion of tears, and every different individual may experience various degrees of these symptoms.
How to Wear Your Silicone Hydrogel Lens
In order for the cornea to adapt to the lenses' shape slowly and to lessen or avoid the adaptive symptoms, you can try wearing the lenses progressively at the start, for example, wearing them for 4 hours on the first day, 6 hours on the second day, 8 hours on the third day, and then start to wear them normally after the fourth day.
Ways to Deal with Adaptive Symptoms
- If you experience the adaptive symptoms such as redness, feeling of foreign objects in the eyes and secretion of tears when wearing the lenses for the first time, please stop wearing them immediately and let the eyes rest completely.
- When the symptoms disappear completely two to three days after not wearing the lenses, you can try to wear the lens again.
- If there is no more discomfort after the second attempt, you can start wearing the silicone hydrogel lenses regularly; but if the symptoms appear again, our lens might not be suitable for you to wear.
- If the symptoms didn't lessen or they became worse the next day you stop wearing the lenses, please seek medical help from an ophthalmologist immediately.
