Disposable Contact Lenses
Since the first sketches of contact lenses done by
Leonardo da Vinci in 1508, these tiny health-conveniences have evolved
to satisfy even the pickiest client and the most unusual prescriptions.
Disposable contact lenses are designed to be worn for a period of
time and then replaced with a fresh one. They have been introduced
to the market in 1987 and are experiencing an ever growing popularity.
Eye care practitioners favor disposable lenses for their convenience
and safety as consumers dont always follow cleaning instructions
with reusable lenses.
Disposable lenses can be prescribed for daily wear
(lenses are removed each night) or extended wear (meaning that you
sleep in them), depending on the needs and eye physiology of the
patient. Lenses have to be discarded because substances in the human
tear, like lipids, calcium and protein can build up on the lenses
and make them less comfortable. This bildup also makes the eyes
more prone to infection. To avoid these inconvenience and health
risks, lenses should be cleaned, but if you want to save yourself
the trouble of contact cleaning then you should use daily disposable
lenses. One-day disposables are discarded every night and replaced
in the morning with a fresh pair. This kind of lense is safer because
there is no day-to-day bildup and no risk of eye injury due to sleeping
Todays advanced technology makes it possible to
produce high quality lenses in greater volume and at a lower cost.
This way diposable contact
lenses are not made of less quality materials, in fact some
of them are made of the same materials as traditional lenses. Today
there is a wide selection of disposable contacts, from simple lenses

practitioner will tell you if there are any disposable lenses that
fit your particular prescription.
