There are three kinds of contact lenses including soft contact lenses, rigid glass permeable contact lenses, and hard glass contact lenses. Most physicians suggest the soft or the rigid glass permeable contact lenses and in very rare cases prescribe the hard glass contact lenses. Bifocal, astigmatic, colored and other contact lenses are all available in these three kinds. Soft contact lenses are made of hydrophilic plastic. As soon as they are applied, they absorb the water in the eyes and become soft and pliable. This allows them to fit perfectly in the eye. They are very popular as vision correction lenses and comfortably contour to most eyeballs without any complications. As mentioned, lenses for people with astigmatism either due to near or far sightedness, bifocals problems, color contacts, and practically every other kind of vision correcting lenses can be found in soft contact lenses varieties. A specialized variety of soft contact lenses are also used these days to reshape the cornea during nights. This helps in giving clear vision even without the contacts during the day, but is not a permanent solution to the problem and the specialized lenses need to be worn every night for good vision the next day. Cornea reshaping helps to encounter myopia during the day. Since most eyes can adjust to the soft contact lenses, they are definitely more popular than other types of contacts. Also, since they mold well to the eyeball, chances of dust particles getting caught and causing irritation is considerably lesser. Patients who use them find it easier to handle them while inserting and removing as they stick to the finger due to their softness. Soft contact lenses require much care. The best option would be to use the disposable kind if the patient can afford them since they are the expensive kind in contact lenses. They must be cleaned in a sterilizing solution if they are not the disposable kind. After the soft lenses are cleaned, they must be stored in storing solution and must not be allowed to dry. In the event the lenses are not clean, they are liable to cause eye infections, irritation, and itchiness. It is suggested to choose disposable contact lenses. If the daily disposable ones are too expensive, the next option would be to change the lens at least once a week or once a month at the latest. Negligence in taking good care of soft contact lenses can result in the lenses causing severe damage to the eyes and wreaking further havoc with the eyesight in the future. |
