Here is a list and description of different contact lenses available for you to choose:
- Disposable contact lenses
Disposable contact lenses are lenses which are designed to be replaced on a
regular basis, usually either daily, two-weekly or monthly. The more often a lens is replaced, the less the lens
will become deposited with proteins and oils. Many of the problems that contact lens wearers experienced when contact lenses
were replaced on an annual or two yearly basis are seldom seen nowadays. Disposable contact lenses are therefore a
healthier alternative.
Daily disposable contact lenses are a great option for people who only want to wear their
contact lenses a few times per week, for example, for sport. They also remove the need for cleaning, since they are inserted
in the morning (or before you play sport) and then thrown away afterward, offering exceptional convenience and good value
for money. Lenses which are replaced two-weekly or monthly are good value if you want to wear lenses everyday. They work out to
be cheaper than daily disposable over the period of two to four weeks, although you will need to clean them nightly.
- Gas permeable contact lenses
Gas permeable contact lenses are usually used for the correction of moderate levels of astigmatism. They provide excellent
clarity of vision, especially in cases where the astigmatism is irregular (such as with keratoconus). They require a
longer period of adaptation than soft lenses.Gas permeable contact lenses offer excellent long-term corneal health
since they allow almost as much oxygen to pass through to the cornea as without a lens on the eye. Many of the problems
associated with the reduced oxygen flow through the old-style "hard lenses" are seldom seen nowadays due to the developments
in these modern gas permeable materials.
