FL41 Sapphire AR UV Lenses for Glasses, was $605+

If you know the dangers of blue light and LEDs these are the best protection. Also essential for recovery from head and spine injuries including concussion and whiplash.

Large lenses, about 6cm by 5cm can be cut down to fit most frames. My optometrist will do it for you for a small fee, or free if you buy frames there (best prices in the city). Lens only.
