When wearing contact lenses for the first time you might be amused thinking about which side is the correct one to wear. If you are among the lucky few who can read the laser imprint you would not require a guide to help you through the process. But if your lens has not got a laser imprint over it then the easiest way to locate the wearable side of the contact lens is to hold it on your finger tip. Make sure you wash your hands thoroughly every time before touching your lenses this secures them from unnecessary harmful deposits. When held over finger tip if the contact lens forms a “U” shape with the edges extended outwards its inside out. You must reverse it before wearing. A contact lens if worn from the wrong side would not do any harm but would be uncomfortable. A contact lens wearable side is when it forms a simple “U” shape with it edges not flaring outwards.
A wide range of contact lenses is available in market. You can expect to have a hard time deciding. All the contact lenses can be condensed under categories depending upon various factors like wear ability, replacement and composition. Based on composition contact lenses come in two broad categories namely soft and rigid gas permeable. Soft lenses are easy to adapt and wear as they contain 25 % to 80% water but are not usually durable. Rigid gas permeable lenses on the other hand are more durable however it takes time to adapt to them. Rigid lenses in some cases offer better vision to individuals than soft contact lenses. There upright payment is mostly higher as they can be used for several years. In case of soft lenses they can be replaced on daily, weekly, monthly and after 1 year. Contact lenses in which one can sleep are known as extended wear lens others are daily wear.
