It has been found that over 125 million people use contact lenses worldwide. People choose to wear contacts for various reasons. They are primarily used because of their appearance and practicality. Compared to glasses, contact lenses are affected very little by weather (such as rain), they do not fog up, they provide a wider range of vision, and they can be worn for almost all sporting activities. For these reasons, contact lenses have become a “modern” trend.
There are several different types of contact lenses. In 2004, coloured contacts only accounted for only 3% of contact lens fits. However, this number has continued to be on the rise as many are seeking to change their overall appearance. Cosmetic contacts, also known as coloured contacts, are designed to change the colour of the eye. They come in a variety of colour including honey, green, grey, and blue. The popular brands for coloured contacts include Freshlook, and Acuvue 2 Colors.
Theatrical contact lenses, a type of cosmetic contact lenses, are used in the entertainment industry to create a confusing appearance. Depending on the particular lenses, theatrical contacts can make one’s eyes appear satanic, cloudy, lifeless, or diluted. Scleral lenses, another type of cosmetic contact lenses, cover the white part of the eye. These are also often used for entertainment purposes. Theatrical and scleral lenses are most often used in horror films. Also, there are coloured contacts that are worn just for fun. These include butterflies, cat eyes, spiders, and flags.
Colour contact lenses can be prescribed or non-prescribed. Some cosmetic stores sell non-prescription colour contact lenses. However, complications due to wearing contact lenses affect roughly 5% of wearers each year. This percentage is at its highest for those who choose to get their contacts from the untrained general public instead of contacting a professional.
