Bifocal Contact Lenses - Are They Ready For You?
Chris Smith
If you are at the age where you experience problems focusing on items
20 yards away, and also on items 1 foot away from you, you
unfortunately have reached the life stage where you will have to
consider wearing either bifocal spectacles or bifocal contact lenses.
You most likely have a condition that goes by the name of presbyopia.
Presbyopia is normally identified when the ability of the eyes to focus
on near objects is reduced with age. This is due to reduced elasticity
of the lenses of the eyes.
People are often born with either nearsightedness or farsightedness.
The first occurs when the eyes can see nearby objects clearly but
distant objects are blurred, and the latter is where distant objects
are focused more clearly than near objects.
Presbyopia on the other hand, is a condition normally associated with
advancing age. You may become aware of the condition when you find you
have to hold the restaurant menu at arms length to be able to read it.
Presbyopia affects the majority of people in their 40s and 50s, but
some privileged men and women may only experience it at a much later
age.
All is not lost for people with presbyopia. A number of options are
available to manage the condition. You may consider wearing bifocal
spectacles, but technology has given you the altogether better option
of using bifocal contact lenses.
Bifocal contact lenses have been around for around 70 years; they first
became available in the 1930s. The original bifocal contact lense were
similar to the early bifocal spectacles, where a distinct line could be
observed between the lenses.
The materials and techniques used to manufacture those first generation
contact lenses were far inferior to what is available today.
Bifocal contact lenses made especially rapid progress after the early
1980s. Daily wear bifocal soft contacts became available for commercial
use in 1982 and disposable bifocal soft contact lenses were first
introduced in 1999.
An exciting development is that hybrid lense, that have a rigid gas
permeable center and a soft outer skirt, have made their appearance in
the summer of 2006. A hybrid lens for presbyopia is amongst the first
of these modern generation lenses to become available.
Contact lens technology has now evolved to the point where bifocal
lenses are not difficult to use at all. If you at first find them
problematic you can rest assured that you will soon get the hang of
them. It will become second nature to put in and take out your bifocal
contact lenses, and forget about them in between.
