Spectacles are the most common means for correcting vision. There are drawbacks to wearing them though. Some people find them uncomfortable because they place pressure on the temples or behind the ears. Others do not like spectacles because they feel it detracts from their appearance or makes them look old. Spectacles also cloud over in wet weather and generally limit a person\’s field of vision. For these and many other reasons, many people prefer to wear contact lenses.

These little discs are worn directly on the cornea to become an integral part of the eye. This is why they give a person a fuller field of vision. They do not cloud over in bad weather and they do not have the discomfort of spectacle frames causing pressure somewhere on the head or face. Once in place, they are invisible.

Apart from vision correction, they are also worn for therapeutic reasons or to change appearance. The eye doctor may prescribe these little discs to help correct certain eye disorders. Other therapeutic indications may be for post surgical healing. Contact lenses are available in soft or rigid formats. There are those which have a long lifespan as well as the disposable varieties. The disposable ones are replaced after every single use. The long term ones can be used for many months if they are properly maintained.

One of the most popular reasons for wearing these contact lens is the fact that they come in a variety of colors. This can cause a dramatic change in a person\’s appearance. At the same time there can be the effect of a personality change to the wearer.

There are many dramatic as well as subdued colors and shades to choose from. The user can change her existing eye color to various shades of blue, green, hazel or violet. This color change lasts as long as the lens is in the eye and can be very effective in fashion photography, film making as well as on the modelling ramp. The tinted ones can be supplied with or without vision correction.

Contacts were expensive novelties when they first appeared on the market. Advances in research and production techniques have brought the costs down so that most people find them affordable. Almost anyone who wants to try these out can manage the price tag. Discounted ones for all uses have flooded the market. These soft lenses are equally as effective as their expensive counterparts in changing appearance or assisting vision.

Discounted lenses are also readily available to online shoppers. The price difference can be a very pleasant surprise. It gets even better if you order in bulk. Many online companies offer a third pair free if you place an order for two pairs.

Be aware that tiny dust particles can become trapped under the little disc and your constant attempts to rub away the irritation can cause irreparable damage. It is important to follow the care instructions for contact lenses to the letter. Ensure that you keep them clean and sterile at all times. Proper hygiene in caring for your eyes is of fundamental importance.
