Today, the majority of lenses worn are of two basic types: rigid gas permeable (so-called "hard" lenses) and lenses. best lenses are smaller and more durable, but require gas a longer period of adjustment for the wearer. Hard contact can correct permeable some vision problems, contacts like astigmatism, that the lenses cannot. The lenses are slightly larger than best lenses. They are more comfortable gas and less expensive, permeable but can be easily contacts torn. gas The latest generations of contact are extended and disposable lenses. extended lenses are intended to be worn for several weeks at a time, while disposable lenses are thrown away every day or every few weeks, or in the newest versions, every day.

The distance between the lenses is for a "standard" person. Generally, this will not be permeable a problem, but if a patient is sensitive or has more closely set eyes, for example, it may pose a problem. Persons contacts buying ready-made sunglasses or reading glasses should hold gas them up to see if they appear clear. They should also hold the lenses to see an object with straight lines reflected off of the lenses. permeable If the lines don''t appear straight, the lenses may be warped or inferior.Patients may sometimes need a few days to adjust to a new prescription; however, problems should be reported, because the glasses contacts may need to be rechecked.contact
