Progressive
Lenses With progressive lenses you’ll get continuous, uninterrupted vision for distance, reading and everywhere in between. Your eyes make a smooth transition between vision zones with no "jump" or distracting lines. Progressive lenses are the most sophisticated solution for presbyopia, or the inability to focus on near objects. They were invented over forty years ago as a superior alternative to bifocals and trifocals. Constant improvements over the years have made them the top choice for people who need multi-focal lenses. Progressive lenses offer comfortable, natural vision at every distance so you can focus on life, not on your vision.
Polycarbonate
Lenses Polycarbonate Lenses from Online Optical Store Consumer interest in thinner, more attractive spectacle lenses led to the development of special lens materials that would bend light differently than conventional plastic lenses. These materials are called "hi index". Among the hi index materials developed for eyeglasses, one has a number of very unique properties and provides special benefits to eyeglass wearers. It carries the generic name "polycarbonate" but is sometimes called by other manufacturer trade names. It is the most-used alternative material for modern eyeglass lenses. Polycarbonate lenses are:
Lighter - Polycarbonate Surpass AR lenses are up to 35% lighter and thinner than standard plastic lenses for greater comfort. UV Protection - Polycarbonate Surpass AR lenses shield your eyes from virtually 100% of the sun's harmful UV rays. Scratch Resistant - Polycarbonate Surpass AR lenses are hard-coated for excellent durability and scratch resistance. Easy Care - Special lens treatment resists dust and smudges, making your polycarbonate lenses with AR easy to clean. Polycarbonate was the first plastic hi index lens and still has one of the highest index ratings (1.59). All the advantages of hi index are included with every polycarbonate lens at no additional charge. Originally used primarily for industrial safety glasses, polycarbonate is now used for children, sports enthusiasts, anyone requesting greater impact resistance in their lenses and for rimless frames.
Hi index 1.74 lenses are perfect for:
Hi index lenses have flatter curves than their lower-index counterparts for a reduced lens profile. A flatter curve, however, can cause off-axis blurred vision. To compensate, the 1.74 lens incorporates optical aspheric technology into the lens design. Not all aspherics are created equal. We have chosen only the industry's most advanced optical performance in a flat design while preserving beautiful cosmetic appeal.
Anti-Reflective
Lens Coatings Anti-Reflective Lens Coatings from Online Optical StoreRegular plastic lenses transmit only about 91% of light to the eye. The rest is lost to front and back surface reflections. However, a revolutionary coating developed to reduce reflections on camera lenses is now available for eyeglass lenses. You will experience crisp and clear natural vision in a brilliance that is not possible with uncoated lenses.
For Working: Artificial light in an office environment quickly leads to eye fatigue and using the computer puts a strain on the eyes. It is particularly important to use anti-reflective coatings to protect your eyes while working. For Appearance: Choose anti-reflective coatings to improve transparency and cut down on the reflections others see in your glasses. You'll enjoy direct eye contact, unhindered by distracting reflections. For Durability: Anti-reflective coatings enhance the quality and expand the lifetime of your lenses by providing superior scratch resistance, durability and resistance to dirt and water.
Transitions®
VI Lenses Photochromic Transitions® Lenses change from clear to dark in the presence of ultraviolet light and block 100% of harmful UV rays. Innovative photochromic technologies have produced unparalleled lens performance in nearly every lens design and material, including shatter-resistant lenses, bifocals, trifocals, progressives, and standard and high index materials. Transitions® Lenses are also perfect choices for children's eyeglasses. Transitions® Lenses begin to darken the moment they are exposed to UV light. The greater the intensity of UV rays, the darker the lenses become. The moment UV rays are no longer present, the lenses begin to fade back. In short, Transitions® Lenses quickly darken when you go outdoors, and fade back fast when you return indoors. Most wearers report that the adjustment happens so smoothly, they are unaware of it.
For Driving
For Childern
For Special Needs Certain people develop a heightened sensitivity to light, known as photosensitivity, and are more susceptible to visible light. Photosensitivity can develop with conditions, such as diabetes or recent eye surgery. The condition can also be caused by taking certain prescription medications. Some medications, even those used to treat conditions not related to vision, can cause the eyes to be more susceptible to damage from UV rays. Patients with special needs are excellent candidates for Transitions® Lenses. For more information about ordering lenses, visit our guide to Buying Lenses Online selection.

These
lenses are nearly 50% thinner than 1.50 index plastic and 13%
thinner than 1.67 index, offering you the ultimate in technology
and cosmetics by reducing the "eye-shrinking" effect
that many high prescriptions have.
Anti-reflective
lenses transmit more light which provides:
Transitions®
VI also has expanded protection at the UV end of the spectrum.
Previous Transitions® Lenses blocked UVA (290 to 315nm) and
UVB (315 to 380nm), but Transitions® VI has expanded protection
up to 400nm. Transitions® Lenses contain special photochromic
dyes that cause the lens to activate, or darken, when exposed
to ultraviolet rays from sunlight. When the UV light diminishes,
the lenses fade back. As light conditions change, the level of
tint adjusts, offering the right tint at the right time. It's
important to note that the UV blockage remains constant. Transitions®
Lenses provide automatic protection from UV rays in both the clear
and darkened states. Perfect Candidates Everyone who needs protection
from glare and UV rays can benefit from Transitions® Lenses.
They are appropriate for children, adults and patients with special
eyecare needs. The tint level of Transitions® Lenses adjusts
quickly as light conditions change to provide convenient protection
from glare and 100% blockage of harmful UV rays.
Windshields
in today's vehicles block most of the UV rays that cause Transitions®
Lenses to activate, or darken. As a result, when worn inside a
car where less UV light is present, the ability of the lenses
to transition to dark is reduced. A new category of lenses, DriveWear®,
Activated by Transitions®, has stepped in with a unique, high
tech solution for driving. DriveWear® lenses combine the glare
protection of polarized prescription sunglasses and photochromics
which respond to both visible and UV light . The result is a lens
that can sense the light coming in from outside of the car and
transition to dark accordingly. Drivewear® lenses are capable
of sensing and reacting to varying light conditions both outside
and behind the windshield of the car. From bright sunlight accompanied
by intense, blinding glare, to overcast inclement conditions,
Drivewear® lenses provide the ideal visual solution.
It's
never too early to start caring for your children's eyes. Children
are excellent candidates for Transitions® Lenses. It is estimated
that 80% of total lifetime exposure to UV rays occurs before age
18. Children are more susceptible to UV radiation because their
eyes continue to develop into the teen years.
