The bifocal contact lenses contain two different powers in a single
lens to solve your eyesight problems. Perfectly healthy people develop problems
in their vision with age. This is due to the normal wear and tear of the biological
organs of the human body and is not a deficiency of any sort. These bifocal
contact lenses serve the dual purposes of clear vision in both the near and
far sights.
The bifocal contact lenses come in as soft lenses and rigid lenses. Advances
in technology are helping with all possible varieties such as lenses of the
disposable kind, replaceable kind, extended wear kind and the normal type. The
spherical design allows the dual power of the lens to pass along gradually,
but within the jurisdiction of the pupil of the eye, which slowly adapts to
use this lens for best viewing.
The concentric design on the bifocal contact lenses has different powers in
the centre and the sides. Your eye will decide on which part to use and when.
Another type of these is the translating design, which sets a perfect demarcation
line to set the two powers apart. Therefore, this lens does not permit any rotation
on the eyeball. This is in conjunction with the age-old bifocal glasses.
Some of you may find it difficult to adjust to the changing nature of the powers
of your bifocal contact lenses. You can find your solution in the monovision
type of such lens. This makes your eye with a better vision help out the weaker
eye while viewing things at a distance, though you might have to keep adjusting
your focal length now and then.
You can use any of the bifocal contact lenses according to your suitability
and adaptability. Once your ophthalmologist gives you the green signal to wear
these lenses, make use of the free trial offers at your optician to finalize
on the most suitable one for your eye. Also, keep in mind that your eyes will
need a certain period to adjust to the new settings and take a few days to decide
on what is best for your eyes.
