The Filter

The AGW®-250 lens was developed to answer requests for even better infrared radiation protection while also reducing the light level perceived by the eye.

It consists of a base lens of our exclusive Blue Didymium™ with a thin layer of either shade 2, 4, 5, 6 or 8 Green Welding (full coverage) laminated to the base lens. This is very desirable when working with high pressure torches and glass requiring very high temperatures.

Suggested uses are: where there is a need for attenuation of bright illumination, such as that generated when working Pyrex®, quartz, Vicor®, platinum jewelry work, and any operation where long periods of time are spent gazing into a high temperature furnace or fire pit.

Quartz workers must use a minimum Shade 8!

The AGW-250 filter is available in non-prescription (plano power), readers, single vision, and standard flat-top D28 bifocal prescription form. 

Thickness Advisory: This filter is thicker than normal lenses. In non-prescription form, it is approximately 4 mm thick. Single vision prescription adds at least 1 mm, bifocal prescription adds at least 2 mm. 

Protected under United States Patent Number 6,612,697.
