We
all wear eyeglasses to correct faulty vision or to protect the eyes from glares
and reflections. The most common complaints that often eyeglass wearer have is
the weight exerted by the glasses and the thickness of the lenses. For people
with strong eyeglass prescription for nearsightedness, farsightedness or
astigmatism often has thick lenses.
Corrective lenses
Wearing
eyeglasses for correcting faulty vision is usually what we do with it. But at
the same time we also want to feel attractive and comfortable in them. Corrective
lenses correct the refractive errors by bending the lights as it pass through
the lenses. Often this light bending
capacity of the lens is given in the eyeglass prescription. The refractive
errors and the corrective lens power are measured in units called diopters. The
higher the diopters the thicker will be your lens. Regular glass or plastic
lenses with higher amount of correction can be thick and heavy. For people suffering from nearsightedness the
corrective lenses are thinner in the center and thicker towards the edges. And
for people suffering from farsightedness the lenses are thicker in the centre
and thinner at the edges. Thus, the stronger the prescription the thicker will
be the lenses.
Why high index eyeglass lenses?
The lens material corrects the same amount of
refractive errors with less lens materials. This means thinner eyeglass lenses.
The lens material is both thinner and lighter than usual lens materials like
glass or plastic. Due to this high index lenses are highly recommended for
people with strong eyeglass prescription. It provides thinner and lighter
lenses giving the eyeglass a better appearance and comfort ability.
· High
index lenses come in for different lens correction such as single vision,
bifocals, progressive, etc.
· There
are different types of high-index lenses at different prices. You can choose
one according to your need and budget.
Advantages of high index Eyeglass Lenses
· High index eyeglass lenses are known for their light bending ability. They come in a variety of refractive indices. Compared to conventional lens material high index lenses are 50% less thinner than other lens materials. Whether you suffer from farsightedness or nearsightedness with higher prescription, the lenses will be thinner than your usual eyeglasses.
· As
the lens material becomes thinner the total weight of the lenses reduces. They
are also more comfortable than most conventional lenses.
· The
‘bug-eye’ effect which results due to strong lens prescription for farsightedness are reduced with high index lenses. The lenses become thinner and the eyes more attractive.
High
index lenses have gained popularity. Its aesthetic and functional value is
unbeatable at the moment. But there is always limitations to it, before
choosing the lens material you need expert advice and opinion. So, consult with
your doctor or optician before buying them. For more information visit - http://blog.eyedo.in/high-index-lenses-for-lighter-eyeglasses
