Most colored contact lenses available in the market today are tinted contact lenses. Tinted contact lenses are pigmented with certain dyes embedded into the naturally clear lens material. The color of the die is responsible for the tint or the hue or tint of the eye. Depending on the strength of pigmentation, the moisturizing colored contact lens can either mask or completely change the tint of the eye.
There are four major kinds of tinted contact lenses available, namely visibility tinted contact lenses, enhancement tinted contact lenses, light filtering tinted contact lenses and color tints.
Visibility tinted contact lens is a lens that has been treated to have a very light blue or green tint for the sole purpose of helping you see it better during application and of course in case you drop it. They are also quite easy to spot in a solution case. Due to the lightness of the tint, these lenses do not change the appearance e of one’s eye, and when worn, you see no coloration through them either.
Enhancement tinted contact lenses are treated with single bodied pigments so as to give the lens a solid translucent color. These are meant to change the color of your eyes, but only to a certain extent and only for certain types of eyes. These are recommended for people with naturally light colored eyes. The extent of the change in color depending on the contract between the wearer’s natural eye color and the color of the lens. The more the contrast, the more vibrant is the result.
Only recently made available to the general public are light filtering tinted contact lenses, designed to help the wearer excel at sports. These tinted contacts do that by filtering out certain wavelengths of light and as a result up to the visibility of other colors, which enable the wearer to see shaper, clearer and in some cases farther as well as protect their eyes from harmful Ultra Violet (UV+) rays. They’re being branded as “Super Lenses for Superstar Athletes”. The amber tinted contact lenses block out the blue wavelength of light and heighten the red, making it easier to see the ball in fast-moving sports like baseball, football, and soccer. The green-gray tinted contact lenses are better suited for slow-moving sports such as golf, which are played out in the open under bright sunshine and these help the golfer distinguish between the various greens of the course easily.
Color tinted contact lenses are solid, opaque tinted lenses used specifically to change the color of the eyes. They are made with multi-layered patterns of different colors fused together to give them the look of the normal cornea. The resemblance between the colors and patterns on these lenses and the cornea of the natural eye are in most cases, picture-perfect copies. They differ from enhancement tinted contact lenses in the fact that they are tinted with solid (opaque) colors and thus are suitable for use on dark colored eyes. These contact lenses are made available in a variety of colors, ranging from violet to green to gray to hazel. Decorative/theatrical contact lenses are classified as color tinted contact lenses, even if they are hand painted vampire contacts, goth contacts or even Chronicles of Riddick contact lenses.
What more should you know before you get yourself a beautiful pair of contact lenses?
Tinted contact lenses are usually sold as Plano or zero power contacts, meaning they can be worn by anyone and technically do not require a prescription. For those who have already prescribed contact lenses, you can let the contact lens retailer know what diopter(power) your eyes have been tested as, and they can make custom contact lenses in the same look as you want for you. However, one should expect to pay a premium for these. A sensitive topic that must be addressed is whether you should purchase contact lenses from a retailer who doesn’t require a prescription. A striking fact may lens buyers are unaware of is that as per law, a retailer can’t sell contact lenses without a prescription, even if they are Plano (zero power), since 2005. This was a result of an increase in the number of reported eye damage cases due to the sale of spurious tinted contact lenses by certain online retailers. The US FDA(Food and Drug Administration) has conducted various studies and has published a list of chemicals that are approved for use in the manufacture of tinted contact lenses. As an informed consumer, one should always check that the retailer conforms to these specifications and constraints their use of chemicals only to the approved one.
Getting a prescription along with a check-up is essential in the interest of your own eyes. If you choose to purchase your lenses from an unknown online store or from a foreign one, it is best to let your optometrist have a look at their site and make sure that you are choosing
