You know the style; strong, bold and distinguished. A frame that works well on almost everyone. If you aren't afraid of a big frame try our wayfarers and you will not be disappointed.

Evening lens: blocks 98% of blue light (400-500nm), independently lab-tested - including the 460-480nm band that suppresses your natural evening melatonin. The step between clear computer glasses and darker pre-sleep lenses, for working late and night gaming.

What to expect: a visible warm tint - whites turn cream while text stays sharp. Choose a Work & Office style when daytime colour accuracy matters.
