Anti-Reflective Lenses - See the
difference |
Regular plastic lenses transmit
only about 95% of light to the eye. The rest is lost to front and
back surface reflections. Now, a new and advanced coating developed
to reduce multiple reflections is available for
all prescription and corrective
lenses. This
Anti-reflective
(AR) coatings will make it easy for
people to see your eyes and have a good eye contact without
distraction.

With Anti reflection

Anti-reflective
lenses transmit more light.
giving you
- improved night
vision
- decreased
computer glare
- reduced eye
strain
- less overhead
fluorescent glare
- and great
looking glasses

Without Anti reflection

Without Anti-reflection coating
You'll catch some disturbing light that reflects back from the lens
back surfaces that reduced vision comfort and caused eye strain.

Hi - Index
lenses
- Lenses are made using different densities.
When a material is more dense, it means it has a higher index.
- Hi-index lenses are made so the lenses are
thinner for higher powers.
- I recommend Hi-Index option for thinner
lighter lenses especially when the spherical (Sphere) power is greater
than 3.00.
- Hi-Index lenses look better, are thinner
and lighter.

(-4.00 D) Left is of normal index
(-4.00 D) Right is of High index
High index lenses are
made of materials that are compressed, or denser, so the same amount of
visual correction is taking place using less lens material than traditional
plastic requires. "High index" means that the lenses are constructed of a
plastic material that has a higher index of refraction. Final result is a
thinner and lighter lenses.
