Eyeglasses have been around since before the 13th century, allowing people to see correctly through a lens. While wearing eyeglasses can be fashionable, they can also be an inconvenience. Now days people do not have to suffer through the obstacles of wearing glasses, all in thanks to the contact lens. Contact lenses were invented to provide a more convenient way to see clearly, and they have been doing so for centuries.
Contact lenses consist of a small, plastic lens which adheres directly to the eye. They come in different assortments with varying purposes. Some lenses are used to correct vision problems, where others are simply worn for cosmetic reasons. Other lenses help fix color defects within the eye. Doctors can also prescribe short term contact lenses to assist in the restoration of an injured eye.
Contact lenses should be carefully inserted onto the eye. Proper care for contact lenses is very important to its longevity and performance. Read more about contact lenses at http://www.macfarlaneoptometrist.com.au/
