The right tint can protect and enhance vision, says Howard Purcell, OD, of Essilor of America, producer of Xperio UV and Transitions lenses.
Gray is a neutral, all-purpose tint that reduces brightness and doesn't distort color.
Brown absorbs blue light and increases contrast on outdoor backgrounds like grass and sky.
Green reduces glare and ups contrast in bright light—perfect for precision sports like tennis.
