Lens Treatments

Scratch Resistant Coatings - recommended to protect lenses from everyday wear-and-tear. FREE! Included on all lenses.  When a spectacle lens becomes scratched, it can impair vision through the lens and present an unattractive appearance. Scratch resistant coating may be applied to both surfaces of a lens to help protect against scratches caused by everyday use. This not only increases the durability of the lens, but also protects your investment. "Scratch-resistance" does not equal "scratch-proof". Because of this, it is important to handle your glasses with care and always place them in a proper case when not in use.

Anti-Reflective Coatings - Reduce both external and internal reflections that occur as light passes through a lens. These reflections are often annoying and are not cosmetically appealing External reflections on the front surface Ar Lensesof the lens can hide a patients eyes. Internal reflections can reduce visual acuity. Backside reflections can cause reflections of your own eye.  AR coating will almost eliminate both of these reflections by increasing light transmission.

AR coatings consist of several microscopic layers of inorganic materials usually applied to the front and back lens surfaces. AR coatings sometimes have a hint of residual color, often a shade of green, depending on the individual manufactures formula.

AR coated lenses also have varying degrees of quality depending upon the number of layers of AR and the base hard coat of the lens. The newest developments with regards to the quality of an AR coating are the oleophobic (oil repelling) and or hydrophobic (water repelling) properties of the AR, both of which keep AR coated lenses cleaner and help them to last longer.

UV (ultraviolet) Coatings - UV radiation consists of invisible rays from the sun. There are three types of UV radiation: UVA, UVB and UVC. UVC rays do not pose any threat, as they are absorbed by the ozone layer. However, exposure to UVA and UVB rays can have adverse effects on your eyes and vision. Short- and long-term exposure to these dangerous rays can cause significant damage damage.

Short-Term Effects of UV Radiation
If you are exposed, unprotected, to excessive amounts of UV radiation over a short period of time, you are likely to experience an effect called photokeratitis. Photokeratitis is an inflammation of the cornea caused by a brief exposure to UV radiation, usually when combined with cold wind and snow. Like a "sunburn of the eye", it may be painful and may create symptoms including red eyes, a foreign body sensation or gritty feeling in the eyes, extreme sensitivity to light and excessive tearing. Fortunately, this is usually temporary and rarely causes permanent damage to the eyes.

Long-Term Effects of UV Radiation
Long-term exposure to UV radiation can be more serious. Scientific studies and research growing out of the U.S. space program have shown that exposure to small amounts of UV radiation over a period of many years may increase the chance of developing a cataract, and may cause damage to the retina, the nerve-rich lining of the eye that is used for seeing. This damage to the retina is usually not reversible. Cumulative damage of repeated exposure may contribute to chronic eye disease, as well as increase the risk of developing skin cancer around the eyelids. Long-term exposure to UV light is also a risk factor in the development of pterygium (a growth that invades the corner of the eyes) and pinguecula (a yellowish, slightly raised lesion that forms on the surface tissue of the white part of your eye.)

Special coatings can be applied to lenses that do not inherently block UV rays. Glass or Plastic lenses must be treated to provide UV protection to 380nm. All Polycarbonate lenses provide this protection.

Tints - can be applied to a lens in varying intensities and colors. Intensities of tint are represented by the percentage of light absorbed by the tint, Grey is the most common color followed by Brown. A rainbow of colors are available including Blue, Yellow, Rose and Green. Tinted lenses are available in solid and gradient.photochromic

Photo chromic Lenses - Sometimes called “comfort” lenses, photo chromic lenses darken and lighten according to light exposure. If the wearer is in the sun, photo chromics darken, if indoors, the lenses are light. Photo chromic lenses are available in virtually all lens materials and lens designs.

Polarized lenses – are the top pick for polarized lenseseliminating glare. Hunters, boaters and fishermen, golfers, and drivers are a few who benefit from polarized lens’ glare-cutting properties. Any surface can create glare in sunlight, including water, sand, snow, windows, vehicles, and buildings. Polarization eases eye stress and fatigue in the sun, and comes in Gray or Brown
