New materials are available that offer stronger, lighter and more
corrosion resistant frames. Titanium and stainless steel alloys are
very strong yet light weight. Flexon frames are so flexible they can be
virtually be run over and still maintain their shape. New zyl
materials, such as SPX are available in plastic frames. This material
offers both comfort and strength.
As you browse through our
frame selection, you'll also notice innovative styling from Lulu

Glass Lenses
The trend in lenses is toward lighter and thinner. This
results in a more cosmetically appealing correction that offers more
comfort to the wearer. The majority of new technology is related to
different types of plastic polymers. Worldwide, glass lenses are being
relegated to a less important role. However, glass lenses enjoy some
popularity locally due to the lifestyles of people here and scratch
resistance inherent in this material.
Plastic Lenses
A rule of thumb for traditional CR-39 polymer
(plastic) lenses is that they are one-half the weight of glass. Newer lenses
are available that are 20% lighter than CR-39. Cosmetically, new
materials will be less thick and bulky while being extremely strong
and impact resistant. Polycarbonate and other new polymers are
commonly used in safety prescriptions for improved eye safety. Scratch
resistant coatings are much improved as are new options in other
coatings.
Multifocal Lenses
The most popular multifocals are the progressive lenses.
Technology has improved greatly to reduce awareness of changes in
lens power. Progressive lenses are available in all materials and
photochromic options.
Anti-reflective coat
Many people like the anti-glare properties of lenses that are
antireflective coated (AR). A/R coated lenses can make night
driving glare from reflections on your glasses disappear. Some
people who spend a lot of time using a computer find A/R coatings can
help relieve visual stress.
Ultraviolet Absorbing Tints
Photochromic lenses absorb the harmful ultraviolet (UV) rays from
the sun. For anyone not interested in photochromic tints there
is a UV coating available for plastic lenses that is virtually
invisible. All the excellent quality non-prescription sunglasses
that we sell have this UV protection. For more information visit
this
website.
Photochromic Lenses
Photochromic lenses were once only available in glass; however most
designs and types of plastic lenses are available with photochromic
capabilities. These are popular with many patients as they may
function well with just one pair of glasses. It is worth noting that any
photochromic lens will not darken as much when you are in a vehicle so
some light sensitive patients require prescription sunglasses or
clip-on sunglasses to drive.
Lens Tints
There is a broad spectrum of tints available for plastic lenses from
single to multi-gradient tints. Glass lenses are also available in a
number tints, although fewer options than plastic.
