Designed for Bright Light
A fixed dark tint reduces the amount of visible light reaching your eyes for more comfortable viewing in bright daytime conditions.
VLT
VLT reference bands; each band is expanded for readability, not drawn to a linear scale.
VLT = Visible Light Transmission. It is the percentage of visible light that passes through the lens. A lower percentage gives a darker view; a higher percentage gives a brighter view.
VLT describes lens brightness. Check the lens specifications for this variant.
This lens provides UV400 protection. Lower VLT gives a darker view; it does not mean stronger UV protection. Photochromic lenses retain UV400 protection in both lighter and darker states.

LENS FAQ
Yes. All TINHAO lens types provide UV400 protection against UVA and UVB wavelengths up to 400 nm, including yellow-tint lenses and photochromic lenses in both lighter and darker states. VLT describes visible-light transmission; it does not measure UV protection.
Polarization helps reduce certain reflected glare from surfaces such as roads and water.
No. UV400 describes ultraviolet protection, while polarization addresses certain reflected glare.
No. This lens type is designed primarily for bright daytime and outdoor conditions.

Measure your glasses, not your face. Enter the full outside width and height of your prescription frames in millimetres, including the frame edges—not just the lenses.
Fit-Over: Both measurements must be within the listed maximum compatible dimensions.
Clip-On: Listed sizes are recommended glasses dimensions, not actual lens dimensions. Shape and clip position also affect coverage; size alone does not confirm fit.
