I have went to the eye doctor and he said he’s had many patients with the same problem. I have been wearing them for 10 years or a little more and never have had any issues. Until recently, I put them in for less than 4 hours. I take them out and both eyes are bloodshot! That night they get a sandpaper feeling and just red. It’s so bad that I had to call off work today. He said that his sister had the same issue and she’s also been wearing them for quite awhile. I just want to know if other people have had any issues with that particular brand?!
