Types of Contact Lens

Here is a very useful breakdown of the types of contact lenses available
today.

Since the introduction of contact lenses years ago, the eye product has gone
through various changes and innovations to meet the needs of the consumers.
There are now more than ten types of contact lenses each with its own
characteristics. You can get a prescription from an eye doctor and decide on
your own which specific brand and type of lenses you want. If you find the
task difficult, you can also ask the doctor for his suggested brands and
contact lens type. The following are the types of contact lenses you can use
depending on your needs and preferences:

* Daily wear soft lenses - made of soft polymer plastic, these contact
lenses allow oxygen to pass through providing a higher level of comfort than
rigid gas permeable lenses. Disposable soft lenses fall also under this
category. They are called daily wear contact lenses because they require
daily cleaning. Although most daily wear soft lenses are disposable there
are also those that can be worn for one whole year. Disadvantages of these
types of lenses include: easy absorption of oils and lotions from your hand
which can irritate your eyes and also less durability than hard lenses

* Disposable soft lenses- disposable soft lenses can be worn up to two
weeks. They still require daily cleaning but they are not designed to last
you months.

* Daily wear disposable lenses- daily disposable lenses are lenses which you
can only use for one day. They are discarded at days end. Although daily
disposables are more affordable than yearly lenses, expenses can add up when
you buy a years worth of disposable lenses. Using daily wear disposable
lenses lowers your risk to eye infections.

* Colored Soft Lenses- Colored soft lenses are perfect for those who want a
fresh look. They serve the same purpose as color contact lenses except they
do come in different tints. Some colored lenses contain tints not for
aesthetic purposes. These light-filtering tinted lenses are for athletes or
sports enthusiasts.

* Extended-wear lenses- Extended-wear lenses are contact lenses that can be
worn for several weeks, usually 30 days without having to remove them. They
can come in either soft or gas permeable types. They are perfect for busy
people who do not have the time to clean their lenses at the end of each
day. * Daily wear rigid gas permeable lenses- these contact lenses are made
of plastic that are not as soft or as absorbent as soft contact lenses but
they allow oxygen to pass through them. They don't tear as easily as soft
lenses do but they can take a few weeks to get used to. These type of lenses
also require daily cleaning.

* Bifocal contact lenses - are solutions for those who are suffering from
presbyopia.

* Toric Contact Lenses- this type of lenses are used to correct astigmatism.
These contact lenses are also bi-focal. And can be made from soft lenses or
gas permeable materials.

* Orthokeratology lenses- these lenses are used for improving vision
problems caused by the corneas shape. These lenses when worn overnight
adjust the shape of the cornea so that the individual can have food eyesight
the following day for up to 12 hours.
