Volk Superfield Yellow Lens Filters have been discontinued by Volk Optical. This product is a closeout item; any yellow filter purchase is final sale.
Removing wavelengths below 490nm while fully transmitting those visible wavelengths necessary for full-color image production, the Yellow Filter Adapter provides patient comfort and retinal protection during typical and prolonged examinations.
To install the yellow filter on a Volk Superfield lens, push the tapered end of the adapter into the lens ring above the engraving label. To remove, gently twist and pull until the filter separates from the lens. |
