Manufacturer: Aura Visual Concepts, Inc.

Aura developed the AGW-250 lens to answer requests for improved infrared radiation protection while also reducing the light level perceived by the eye.

It comprises a base glass lens of our exclusive True Didymium™ with a thin layer of either shade 3, 4, 5, 6, 8, or 10 Green Welding (full coverage) laminated to the base lens. This is very desirable when working with high-pressure torches and glass, requiring extremely elevated 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 the artist spends prolonged periods of time gazing into a high-temperature furnace or fire pit.

Quartz workers must use a minimum of Shade 8!

The AGW-250 filter is available in non-prescription (Plano power), readers, and single vision prescription forms. Purchase Readers through the single vision selection.

Thickness Advisory: This filter is thicker than normal lenses. In non-prescription form, it is approximately 5 mm thick. Single vision prescription adds at least 1 mm. Shade 10 filters are 7 mm thick.

Because of the extreme darkness of the filters, Shades 8 and 10 are available only in non-prescription form.

Shades 8 and 10 are Custom Made and Not Returnable except for manufacturing defects.

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

AGW-250 - Single Vision Rx

AGW-250 Single Vision Prescription Lenses. In addition to the desired shade number, we need the following details to correctly manufacture single vision prescription lenses for you: Your prescription as it is written out as it is on the form you received from your optical professional like this: Right Eye Sphere x.xx Cylinder x.xx Axis xxx followed by Left Eye Sphere x.xx Cylinder x.xx Axis xxx. If your prescription requires prismatic correction, please note the amount for each eye after the entry for Axis and the direction: in, out, up, down. If your prescription is spherical only, you may see the letter DS or a line through Cylinder. Just enter the data as shown on your prescription. Replace xx with the numbers on your prescription, please be sure to include any plus (+) or minus (-) signs as indicated. The second thing we need is your Pupillary Distance. This is a measurement of the distance between your eyes and can be listed as a single number, for example: 64, or as a "split PD" such as: 32/32. Either way is acceptable. Note that PDs are required for all corrective eyewear and that we cannot process your order in our lab without it. Failure to provide a PD at the time of your order will result in your order being delayed until we receive it.
