Special effects contact lenses use to only be available to the movie and television industry. That is no longer the case and now you can have contacts that cause your eyes to glow in the dark or resemble cat's eyes, reptile eyes or even be custom painted to your own liking.
Three types of special effects lenses are available:
One type covers the iris (the colored part of the eye) with a color or artwork design. This type of contact is commonly called "round" and is the least expensive type. Round contacts are available in prescription or decorative only variations.
Another type is one that covers the entire surface of the eye including the white, called scleral contacts. This type of contact can limit the vision and may damage the eye itself if not inserted and removed properly. These are also available in prescription or strictly decorative variations.
The last type is one that covers the entire eye, but leaves a little corner of white visible. These are called semi-scleral and carry the same hazards as the scleral versions. They may be uncomfortable and limit the time that they can be worn safely.
The most popular designs of special effects contacts usually come in prescription as well as non-prescription powers which means that they can also be worn by people with myopia.
You are probably wondering how many times the special effects contact lenses can be worn. The answer is a little quality/price and a little how you take care of them.
Again, you get what you pay for, so a better quality of contact will last a bit longer and be wearable more times. It should be noted that these are NOT unlimited wear. They do wear out.
But even a quality pair of special effects contacts need to be taken care of properly. Keep them in their case and cleaned between wears and they will last longer than most. Even a pair of special effects contact lenses can lead an extended life with proper care.
The effect of these contacts will enhance your Halloween costume or just add a fair to your appearance on a daily basis. Either way, you can have the eyes you always wanted.
