Coastal Contacts offers a wide array of novelty lenses in both plano (non-prescription powers) and prescription powers. The cheapest available are from the manufacturer Marietta Vision. They can cost under $50 dollars per lens but the more intricate the design, the higher the price, with some costing several hundred dollars.
According to LensShopper.com, the WildEyes line of special effect contacts manufactured by Ciba Vision is very popular. They can run from under $50 to over $80 per lens depending on the retailer. LensShopper says, "The different styles and effects are close to endless but some that always seem to be in demand are red hot (deep red), hypnotic (a spiral pattern), wildfire (a sunburst pattern), knockout (An X instead of a pupil) and cat eye."
ExtremeSFX.com offers "Budget" and "Value" special-effect contact lenses. Each design is approved by the Food and Drug Administration (FDA). The FDA warns, "You must see your eye doctor before shopping for Halloween contact lenses to get proper fitting and instructions as well as the necessary prescription. You will need this whether you ordinarily wear prescription lenses or not. And don't even think of purchasing decorative lenses from any store (online or off) that doesn't ask for your prescription; it is illegal."
The firm 9mm SFX specializes in custom theatrical contact lenses. The company has provided special-effect contact lenses for numerous films and television shows such as "300," "28 Days Later" and "Chris Angel Mindfreak." The company's products are approved by the FDA. It sells lenses with both a clear edge –- which means there is a portion of the lens that is either white or clear beyond the color, and sclera – which are full, solid-color lenses.
