Contacts are available for daily wear or extended wear. Well, what does this mean? Extended lenses can be worn from two to four weeks due to the material they are made of. These contact lenses allows more oxygen to reach the cornea of the eye, where as soft contact lens are made of materials that incorporate water.

Extended lenses are soften by water and this makes them to be more flexible allowing more oxygen to reach the cornea of the eye. Most individual's choose to wear their extended contact lenses about seven days before removing them. Contacts should be FDA approved. Extended contact lenses have been known to be worn for several days with no complications.

The cornea of the eye is allowed to get much more oxygen while wearing extended wear contact lenses. You should get around six times the amount of oxygen to the cornea than other disposable contact lenses. Bacteria is repelled much better with this new material than the old material.
