I do but I take cod liver oil 2 T. and drink apple cider vinegar and that seems to help it, especially the oil... I use Twinlabs liquid...about 30 minutes after I used the Twinlab oil, my eye sight improved!!! I would not lie to you, hope that it works for you!!! THE BRAND IS IMPORTANT BECAUSE BEFORE THIS I WAS USING WALGREEN'S BRAND AND NOTICED NOTHING DIFFERENT AFTER MONTHS OF USE...
