Contact Lenses And Its Types

Not until the late 19th century, however, that a German glassblower produces lenses that can be seen through and quite tolerable, and optometrists Germany came up with and include the first contact lens, which can be worn for a few hours at a time.

Types of contact lenses

While contact lenses are still the most used for vision correction, there are also contact lenses for the purpose of purely cosmetic and novelty.

Colored contact lenses can improve or completely change the hue of your eyes, and costume contact lenses can help create some special effects that you see on the big screen.

All contact lenses, however, are medical devices regulated by the US FDA. Prescription contact lenses and cosmetic contact lenses all require a prescription.

This is because even common complications such as infection and inflammation can lead to vision loss or blindness.
