The four kinds of colored lenses are:

• Visibility tint – Lightly tinted lenses. The tint is intended to make it easier to find the lens when dropped. It does not affect the natural color of the eyes.

• Enhancement tint – Darker than Visibility tint with the clear intent to enhance the eye color. The color film is translucent.

• Color tint – Lenses to completely change the eye color. The center is clear. These Lenses are more a fashion item - be aware this may sometimes be fun for nightlife and private parties but in general it is not a suitable "every-day-solution". Wearing lenses without any medical reason we can not recommend.

• Light-Filtering Tint – Used by sport professionals and also their fans. Certain colors will be enhanced, so that yellow or white sports balls can be seen more intense. Again: from the medical point of view this makes no sense and especially everyday-use can not be recommended.
