Types Of Contact Lenses
There are many different types of Contacts, each are great to improve your vision, but not all Contact Lens are created equal.. Although your doctor will help you select the best pair for your eyes, you should always know a little bit about the contacts that are available to choose from. All contact lenses can be separated depending on their wearing schedule, purpose, material, and over transparency.
Contact Lens Materials
Contacts can be separated or best determined by their material. Contacts are
divided into two main groups - soft and rigid (hard). Soft lenses are gas permeable
to a certain extent, being further categorized by the amount of water they contain.
Soft contacts can have either a low, which is less than 50 percent moisture,
or a high moisture content, which is more than 50 percent. Rigid or hard contacts
on the other hand, are much harder in material and are considered to be gas
permeable.
Contact Lens Wearing schedules
Hard contact lenses can last for months, possibly even years before they need
to be replaced. Soft contacts on the other hand, have a schedule for replacement.
Some may need to be removed every 2 weeks, monthly, or even daily. The more
advanced contact lenses, such as Night and Day contacts, will allow you to wear
them all day and all night. Just like other contacts however, you will still
need to clean them on a regular basis to ensure that the protein is removed.
Contact Lens Designs
The designs for contacts are divided into three areas - toric, spherical, and
multi-focal. Toric lenses are for those who have astigmatism, spherical is for
short sightedness, and the correction of long sightedness, and multi-focal contact
lenses are used in the correction of presbyopia. All three designs have their
distinct purpose, and you should always ask your optician before you rush out
and buy one.
Many different purposes
As you may already know, contact lenses serve different purposes as well. They
can be optical, therapeutic, cosmetic or decorative. Optical are the most common,
as they are for the correction of vision and anomalies you have may have. Therapeutic
lenses are normally soft contacts that serve to protect your cornea. They are
also used as a reservoir for certain medicines that are used to treat various
cornea diseases and malfunctions.
Decorative contact lenses are basically color contacts that produce various effects, such as rainbow colors, cat’s eyes, and so on. Cosmetic on the other hand, are meant to change the overall appearance of your eyes. Most types of cosmetic contact lenses are designed to enhance your overall eye color.
The type off Contact Lens for you
With there being several different types of contacts available on the market,
you should consult with your optician to find out which are the best for you.

toric lenses. If you don’t know anything about contact lenses, you may

your vision and often times protect your eyes, which is why you want to choose
them carefully.
