Corrective Contact Lenses and Cosmetic Contact Lenses

The crazy contacts and Halloween contacts contain polymers that are cheap. Hence such lenses cannot be worn as an extensive wear and expire after a small trial period. The color pigments and paints in the contact lenses make them look beautiful in the eyes. There is a luminous material that is inside the glow in the dark contact lenses. It is a fairly new invention by Contact lenses manufacturers. However if you are not sure which pair to buy then you must order a free trial pair of contact lenses from any online store.Two of the major types of contact lenses are corrective contact lenses and cosmetic contact lenses. Corrective lenses are made from soft polymers having 60 to 70 percent of water. Dry eyes contact lenses have very less or almost zero moisture which makes the contact lenses comfortable for dry eyes. RGP lenses are made of a special polymer that contains no moisture at all and is specifically used in making dry eyes contact lenses.
