Ensure no harm comes to lenses in the grinding process with our optical lens pads, suitable for all shapes and styles of eyewear. These technologically-developed foam pads have been designed to promote best practices of care when dealing with lens augmentation.Sticky foam pads attach to all models of grinding machine, making our selection versatile for every glasses manufacturer. Avoid costly scratches and machine marks with lens blocking pads, which fix to each side of the lens, holding it securely in place for grinding, without compromising the quality of the glass. With consistently low torque, our optical lens pads allow for accurate edging and, being supplied with non-adhesive tabs, are applied with complete ease and precision.

Condenser lenses are molded lenses designed for illumination applications. Featuring large apertures and short focal lengths, condenser lenses are commonly used in emitter-detector applications, projection applications, or condensing illumination applications such as koehler illumination. The aspheric condenser lenses are molded on the aspheric surface and ground and polished on the opposite face, offering superior performance.

A mirror is an object that reflects light in such a way that, for incident light in some range of wavelengths, the reflected light preserves many or most of the detailed physical characteristics of the original light. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light.

The blue light is the most harmful light in all visible light. The risk of stargardt's disease (fundus flavimaculatus) will be improved after a long-term exposure on blue light which exist not only in outdoors but also indoors such as computer screen, office lights, smart-phone screen. However, anti-blue lenses can effectively block these harmful blue lights to protect eyes and reduce the risk of stargardt's disease.
