Extended wear contact lenses

Extended wear contact lenses are type of contacts which allows their wearing a longer period of time without having removing from the eye at night. For many people the fact that they could each morning get up out of bed and do not insert your contact lenses in the eye very important. This is especially true if you are moderately or severely nearsighted, and you are not able to get without eyeglasses to the bathroom or kitchen.

For many people the idea, that they will have to grope in the dark around the nightstand and looking for eyeglasses is a nightmare. For example, for mother who must get out of bed in the middle of the night and take care of sick or crying child, or simply just go to the toilet.

For these people, as well as for almost anyone who needs vision correction and have problems with manipulations of contact lenses is more ideal to choose this option. Contacts for extended wear may offer this option for many people. Soft contact lenses for extended wear are made of material that is highly permeable to oxygen. They are hydrophilic polymeric materials. They are generally designed to allow a longer period of time, 7-30 days of continuous wear without removal, cleaning and disinfection. Soft contact lenses allows the cornea to receive the required amount of oxygen.

More advanced technology has allowed expansion of these types of contact lenses. They are made from silicone-hydrogel material, which offers many advantages. Allows to supply up to 6 times more oxygen than the conventional hydrogel contact lenses. Generally they do not have a problem with drying as other types of soft contact lenses. They have a special biocompatible coating layer, which reduces the amount of accumulated protein and bacteria. This is important because proteins and bacteria accumulated in the contact lens can be a source of infection. As with all contact lenses for extended wear, there is always the possibility to affect the health of your eyes, even when there are no obvious problems. Although extended wear contacts can be very desirable because it provides great comfort are the most risky type of contact lenses.
