Each filter colour has a Visible Light Transmission (VLT) figure, which indicates the percentage of light passing through the filter. A low value will block more light from entering the eye; a high value allows more light into the eye. You should avoid a VLT% that is too dark for your needs for safety reasons.
The grey filter offers a comfortable, true colour rendition and may assist in cutting glare.
The economic plastic frame comes in two sizes, medium and large. Medium is suitable for the average adult.
Please note: Frame images are shown in greyscale, please refer to the colour swatch above as a guide to the tint of these filters.
