• Introduction

    Contact lenses are considered medical devices and can be worn to correct vision, or for cosmetic or therapeutic reasons. People choose to wear contact lenses for many reasons.Aesthetics and cosmetics are often motivating factors for people who would like to avoid wearing glasses or would like to change the appearance of their eyes.Other people wear contacts for functional or optical reasons. When compared with spectacles, contact lenses typically provide better peripheral vision, and do not collect moisture such as rain, snow, condensation, or sweat.

    Contact lenses can be classified in many different ways. Contact lenses can be separated by their primary function, material, wear schedule i.e.how long a lens can be worn before removing it and replacement schedule i.e.how long before a lens needs to be discarded. Typically, soft contact lenses are mass-produced, while rigid lenses are custom-made to exact specifications for specific individual patients.

    When it comes to contact lenses, it’s very important to know exactly what’s inside of them, or better yet, what they’re made of. Materials used have varied throughout the years. Earlier times called for more rigid materials that didn’t allow much oxygen to get to your eye. But as technology has improved, so has the availability of products.
