I don't wear contacts but I have a coworker who had dry eyes until she tried Bilberry supplements, in the vitamin section. She said the relief was amazing and noticeable by the next day, and when she stopped taking it, they were dry again. It's very inexpensive and she says it also is said to help with night vision, used by the military back in the day. She is certain it's why she is almost 55 and still doesn't even need readers. She's the only one over 40 I know that doesn't need glasses.
