We do recommend that you consult your eye care professional for a fitting, especially if you’ve never worn contact lenses. Your doctor will instruct you in wearing and caring for your lenses which is crucial for the health of your eyes and for maximizing the lifespan of your contacts. Mishandling the lenses can easily result in damaging them. (See: How long will special fx contact lenses last?) Our contacts are all medium base curve like most national brands. They fit 98% of people. Only certain color contacts lenses listed can be made within a range of correction (-0.25 to -6.00), everything else is available in plano (0.00). Toric lenses are NOT available. As with any contact lens, if you experience more than mild, temporary discomfort, take your lenses out.
