If you are tired of wearing thick glasses in order to correct your big sight defect, then you might consider switching to contact lenses. Before Biofinity XR contact lenses appeared on the market it wasn't such an easy thing to do as contact lenses with hight prescription were practically unavailable. Now you don't have to pay astronomical amount of money for your custom made contact lenses with hight prescription, you can just buy a box of Biofinity XR and enjoy healthy, crisp vision and great looks on a daily basis for up to 30 days and nights continuously. These contact lenses are available in prescriptions from -20.00D to -12.50D in minuses and from +8.50D to +15.00D in pluses.
These lenses are available only in very high prescriptions. If you are after lower powers, check out Biofinity contacts.
