Anti Reflective (A-R) Coating
Provides nearly total light transmittance for the maximum reduction of reflection. This increase in light transmittance permits you to see things more clearly, with crisper detail.
Bifocal Lenses
(JP)—Multifocals with lines that provide (correction for both distance and near vision) two fields of vision: distance and near. There is no correction for viewing at the intermediate distance.
Mirror Coating
A special treatment applied to the front surface of each lens through a vacuum process that allows the lens to take on the properties of a two-way mirror. It reflects the harsh light rays that are emitted from surfaces such as water, snow, and ice.
(JP)—A thin metallic coating over tinted lens, either glass or plastic. The coating reduces overall brilliance of light and is recommended for water or snow sports.
Multifocal Lenses
(JP)—Can be divided into two categories: lenses with lines and lenses with no lines.
Polarized
The best way to cut down on reflected glare. Although regular tinted sun lenses will reduce the amount of visible light, they offer little protection from glare that is caused by reflections off of the water, snow, or shiny objects.
(JP)—Feature a polarizing filter sandwiched between pieces of tinted glass, plastic, or polycarbonate. They eliminate glare created by light bouncing off of surfaces such as water, sand, or snow.
Single Vision Lenses
(JP)—Provide correction with only one focal point. They correct hyperopia or myopia, including the condition of astigmatism.
Tints
(JP)—Can be applied to glass and plastic lenses to provide an additional health benefit by reducing eyestrain. The color often is based on the consumer's preference.
Trifocal Lenses
(JP)—Multifocals with lines that provide (correction for three fields of vision, including distance, near, and intermediate in one lens) three fields of vision.
Ultraviolet (UV) Coating
(JP)—Reduces the absorption of UVA and UVB rays that can damage the cornea. The coating is clear and applied to the lens before tinting.
