So, here is what I've got.
What is a contact lens?According from Mr. Wiki, a contact lens is a corrective, cosmetic, or therapeutic lens usually placed on the cornea of the eye. It has been estimated that 125 million people use contact lenses worldwide (2%), including 28 to 38 million in the United States and 13 million in Japan. The first man to introduce the concept of contacts was the famous Leonardo Da Vinci and was developed by many marketers and inventors as time passed by. And now, we have what we call contact lens in varieties of colors and designs just like the designs of shirts in digitizing services.
Advantages
1. Practicality/Health PurposesWhen compared with eyeglasses, contact lenses are less affected by wet weather, do not steam up, and provide a wider field of vision. They are more suitable for a number of sporting activities. Additionally, ophthalmological conditions such as keratoconus and aniseikonia may not be accurately corrected with spectacles. Above all, compared with eyeglasses, contact lenses generally offer better sight.2. AppearanceContact lenses move with your eye, allow a natural field of view, have no frames to obstruct your vision and greatly reduce distortions. They do not fog up, like glasses, nor do they get splattered by mud or rain. Also, numerous people feel they look better in contact lenses.
DisadvantagesComplications due to contact lens wear affect roughly 5% of contact lens wearers each year. Excessive wear of contact lenses, particularly overnight wear, is associated with most of the safety concerns. Problems associated with contact lens wear may affect the eyelid, the conjunctiva, the various layers of the cornea, and even the tear film that covers the outer surface of the eye. You may need medical practitioners in discounted scrubs and eye charts when this happens.
Types
Corrective contact lensesCorrective contact lenses are designed to improve vision. Therapeutic contact lensesSoft lenses are often used in the treatment and management of non-refractive disorders of the eye. A bandage contact lens protects an injured or diseased cornea from the constant rubbing of blinking eyelids thereby allowing it to heal.Cosmetic contact lensesA cosmetic contact lens is designed to change the appearance of the eye. These lenses may also correct the vision, but some blurring or obstruction of vision may occur as a result of the color or design.
Colors of Contact LensThere are actually many varieties of colors of contact lenses. I'll just give here some of the basic colors.

Odd/Bizarre Contact LensI consider them bizarre not just because of their colors but also of their designs that could already be a design in digitizing service. :) They are odd for the fact that a normal person with an eye defect that needs contact will not choose these designs, but rather these are very appropriate in a Halloween party, horror movies and for appearance purposes only (seldom are medical purposes). Here are some of these bizarre and odd contact lenses.
