several months ago, I started using latisse. I liked the way my eyelashes looked, but around the 4th month, i noticed my eyes started feeling funny, so i stopped using the lattisse altogether. it's been a couple months since I stopped using latisse, but i noticed about 3 weeks ago that I have persistent problems focusing, and I feel slight headache and nausea. last saturday, I went to an optometrist and was told my prescription was too strong (-4.75 r, -4.5 left originally). she told me I should be a -4.25 r and l, and that everything else about my eyes looked totally healthy and normal. she said that with the lower prescription, i should find that my eyes feel better. well, it's been almost a week since i was given the lower prescription, and i'm having the same problems- trouble focusing (like my eyes are constantly tired), and i have a low grade headache and nausea. I'm not sure what I should do next? Should I make an appointment with a neuro-opthalmologist, or should I wait longer with the new prescription? Even without my contact lenses, my eyes are having problem focusing. Anybody know what this might be? I was looking at symptoms of accommodative spasms and thought it might be that, but wouldn't my optometrist have given me drops or something for that? Please help!
