Sunglass tint is the visible color and darkness applied to a lens. Its purpose is to filter visible light, reduce brightness, and improve visual comfort and contrast in varying environments. Tints are categorized by color (gray, brown, green, etc.) and by density (lightness/darkness), but it is crucial to understand that the tint itself does not provide UV protection; that is a separate, invisible coating or treatment.

The color of the tint affects contrast: gray or smoke tints reduce brightness without distorting colors (neutral), while brown or amber tints increase contrast, making objects stand out, which is ideal for sports like golf or fishing.
Tint is about visible light and comfort. UV protection is about invisible radiation and eye health. A dark tint without a UV400 rating is dangerous because it causes the pupil to widen, letting in more damaging, unfiltered UV rays. Always prioritize the UV400 label over the tint color.
Gradient tints are lenses that are darker at the top and gradually lighten toward the bottom. They are designed for drivers who need sun protection when looking ahead at the road but require a lighter area at the bottom to see their dashboard clearly. They are excellent for everyday driving but less suited for high-glare environments.
Neutral gray tints are generally recommended for driving because they reduce brightness without altering color perception, ensuring traffic signals and brake lights are seen accurately. Brown or amber tints can be suitable but may distort traffic light colors slightly, requiring caution.
Is a mirrored lens a tint?
A mirrored coating is a separate metallic layer applied over the tint. It further reduces visible light and glare by reflecting light away from the lens, but it is not the tint itself.
Can I get polarized lenses with any tint color?
Yes. Polarization is a filter embedded inside the lens material, and it can be combined with virtually any tint color to achieve both glare elimination and desired contrast.
Does my prescription affect my tint choice?
No. The darkness and color of the tint are separate from your prescription. You can apply the same tint choice to a non-prescription lens or a lens with your full prescription.
