I ve been wearing contact lens instead of glasses for 3 years now. Last month, I stopped wearing contact lens for a while and started wearing my glasses more bc it s more convenient for me at the moment. Now that I m starting college again, I bought new contacts and started using them again. It s been 3 days and I noticed that after 15-20 minutes of wearing it, my vision becomes quite hazy and I can see rainbows around lights. I also find myself to be sensitive under the sunlight. My eyes doesn t feel hurt but it does makes me feel uncomfortable. When I took of the contacts, my vision was still the same. I decided to wait a like longer and after an hour or so, my vision becomes normal again.
