There are two types of contact lenses which are being used today. These include soft lenses and rigid gas permeable lenses or RGPs.

The major difference between the level of comfort is that soft contact lenses are easier to wear because of being more movable compared to RGPs. Moreover, the oxygen flow to the cornea is also more frequent in case of soft contact lenses, making them more comfortable to wear.

As the name suggests, Rigid Gas Permeable lenses are a bit rigid and fix well, and at the same time, they give clearer sight. Moreover, they have a longer life because of being more durable.

Both these type of contact lenses are available in disposable form. However, soft lenses are being used more frequently than that of RGPs. These soft contact lenses are also called extended wear lenses and are in more demand as compared to RGPs because of letting more oxygen flow to the cornea and thus ensuring comfort. However, a few RGPs can also be used as extended wear lenses.

In addition to these two, there is a third category called specialized contact lenses which can further be divided into two types. Orthokeratology-K or ortho-K bring temporary change in the cornea’s curve, letting it see the objects more clearly. However, there is no permanent change in cornea’s curve and it would return to its earlier shape once ortho-K is removed.

The second subcategory of specialized contact lenses is decorative lenses which do not produce any temporary or permanent change in the cornea, nor are they used to correct any eye disorder, rather their only use is to color your cornea e.g. to make your eye color compatible to your costume on Halloween. However, the eyes are exposed to the same risks as with the corrective lenses.

Taking Care of Eyes with Contact Lenses

As we all know wearing contact lenses also demands some care for your eyes and lenses. Some instructions are always to be followed. Always keep in mind to keep a pair of glasses with you to face such circumstances as the loss of a lens or irritation caused by lenses. Moreover, it is also advisable to wash your hands before you wear contact lenses. It would help reduce the chances of infection.

One important thing related to hygiene is to make sure that you clean the lens case every time you put the lenses back in the case after using them. It is imperative for safeguarding your eyes as well as your contact lenses. It would halt the bacterial growth in the case.

Moreover, do not use any type of contact lenses before consulting an eye specialist. He is the best person to decide which lenses would suit your eyes if they suit you at all.
