It could be that your perscription is incorrect, but it could also be that you're just that sensitive to the material of the lenses. Evidently the thin frames aren't as clear. I recently got a new set of lenses and went through 3 types before I had to go back to my old thick plastic lenses before I was comfortable. I spoke with my optomatrist about it and she said somepeople are just that sensitive to the clarity of the different materials. YMMV, just been using glasses for 15 years and use them in front of the computer for 10 hours a day or more.
