Refractive Index (Thinness)
Our glass lenses are all plastic lenses.
The more material with a large refractive index is used, the more it is possible to have a thinner finish in lenses of the same power.
Sunlight contains ultraviolet rays such as UV-A waves that are known to tan the skin and form blemishes on the skin or cause skin to sag and UV-B waves that are believed to cause skin aging and form skin blemishes or freckles. Lenses furnished with a function to cut out these harmful ultraviolet rays are called "UV-cut lenses."
Seiko’s UV-cut process results in the elimination of more or less 100% of ultraviolet rays of 400 nm or less.

Scratch-resistant Coating for Prevention of Lens Damage
This is a process that improves the resistance of plastic lenses to scratches, the greatest drawback of this type of lens. Normally, all SEIKO lenses are provided with a coating for protection against scratches as standard.
The grime-resistant coating is a new high-quality coating that realizes enhanced lens surface water-repelling and oil-repelling performance.
This groundbreaking coating features a remarkable improvement in the contact angle between the lens surface and the attached matter, demonstrating the ability to quickly repel substances such as water and oil. In addition, compared to older products, the coefficient of friction on the lens surface is 60% lower, making it possible to easily wipe off grime that contributes to lens fogginess such as sebum, fingerprints and substances that become attached while performing housework, including for example, oil film and cosmetics.
A grime-resistant coating makes it so much easier to care for spectacles and greatly enhances usability.
Super-Resistant-Coat-BR, Super-Resistant-Coat, Super Hydrophobic coat, Super-Clean-Coat-BR / Keep-Clear-Coat-BR, Super-Clean-Coat / Keep-Clear-Coat and Fogless coat cannot be ordered together.
Heightens spectacle lens surface hardness to improve scratch resistance performance. Also consists of an additional anti-static function to prevent static electricity occurring on the lens surface during wiping, for example.
Resists attachment of substances such as "dust and pollen" and improves wiping performance to achieve improved comfort of use.
Static electricity readily accumulates on ordinary plastic lenses, attracting substances such as dust and pollen. This coating features a special film (conduction film) that releases static electricity, making it difficult for substances such as dust and pollen to become attached to the lens surface.
Fixed in place 1.5 mm from dust with the concave side of the lens facing downward. Dust attached to the convex side photographed after rubbing the concave side back and forth 20 times. (Dust shown in the photograph: Produced by scraping Styrofoam)
The anti-fogging coating is a new type of coating that prevents lenses from fogging when exposed to changes in temperature as the wearer moves from one location to another.
Powerful anti-fogging effects and high sustainability can be realized by carrying out simple, regular maintenance by coating the coating film that features high hydrophilicity with maintenance cleaner with an even greater degree of hydrophilicity.
*Fogless coat cannot be ordered together with Super Hydrophobic coat, Super-Clean-Coat(SCC) or Keep-Clear-Coat(KCC).
