Filter Number: 50
Lens Colour: Yellow
Visible Light Transmission: 87%
Protection: Ultraviolet, Blue Blocker (100%)
Recommendations:
Poor Vision in Darker Conditions
Improve Contrast Sensitivity
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 yellow filter has the potential to enhance contrast, improve visual acuity and brighten images.
The child fit over (#41) is a universal size and has adjustable temples for a comfortable fit. This frame may also be suitable for a smaller than average adult. The non fit over is designed to be worn without prescription spectacles, it has a wraparound style and is available in two sizes, small and medium.
Please note: Frame images are shown in greyscale, please refer to the colour swatch above as a guide to the tint of these filters.
