All About Contact Lenses

Contact lenses have been around for a bit, but newer technology has made them more comfortable and convenient to wear.  Most doctors will offer the option of wearing contact lenses if they have suggested your wear glasses all the time.  Wearing contact lenses is a personal decision.  It is a matter of what your life style can manage, for some the hassle of putting in the contact lenses and remembering the solution and changing them is too much, for others they don’t want to wear glasses all the time.

When contact lenses were first invented they were rather rough and rigid.  Czech chemist Otto Wichterle and his assistant invented the modern soft contact lens.  The modern contact lens is tinted slightly blue in order to make it easier to see in the solution.  Modern technology has even allowed for contacts to be colored for a specific eye color as well as have UV protection in them to protect the eye.

There are two types of major contact lenses – soft or rigid.  The soft contact lens is extremely thin and comfortable to wear, while the rigid contact lens is hard but gives crisper, clearer, vision and can correct most vision problems.  They also last considerably longer than the soft lens.

The next step is to decide how often you would like to change them and dispose of them.  There are four main categories – daily wear, flex wear, extended wear and continuous wear.  Daily wear are only worn during waking hours, flex wear can be slept in for a night or two (like a weekend), extended wear can be worn for a week, and continuous wear can be worn for a month.

You then have daily, weekly, monthly, and quarterly disposable lenses.  How often you dispose of your lenses is a very personal choice.  It is a matter of what your eye is comfortable with.  Many people who have allergies find that disposing more often is helpful because the dust and dirt doesn’t collect as much.

There are many new technologies helping to create better contact lenses for specific problems.  For instance the Toric contact lens came out recently which helps with astigmatism by fitting your eye and giving more power in one direction.  Talk to your doctor about the best options for you.
