      the lenses
      Designed for night-time, these orange-tinted lenses specifically target the range of blue light that affects melatonin production (the sleep inducing hormone).

      By blocking this range of blue light, our Ultra lenses encourage healthy melatonin secretion and a quality night's rest.
      what's included
      All of our Ultra glasses come with a sleek hardcase and microfibre cleaning cloth.

      We offer free shipping and free returns on all purchases, plus a 12-month warranty.
