These drops are amazing. I was experiencing sensitivity to light, which caused me to have headaches. Also my vision is bad. I’ve been wearing glasses since I was really young. So, I used these drops and within the first few times of using these drops my eyes wasn’t as sensitive to light anymore. But using these drops are a bit painful, but the pain gets less intense as you continue to use them. Also the pain isn’t harmful at all, and once the pain calms your eyes feel refreshed. But this product is so rewarding. It has now been about 3 months and I went to my eye appointment and I was told my vision got slightly better! I wasn’t using the drops as often as recommended, so I can only imagine the results I’ll get if I did. These results have now encouraged me to use as recommended. So I highly recommend these drops. They are legit!
