A socially conscious company Circadian Eyewear has partnered with Sightsavers to make a small difference in the world, which can make a significant difference in someone's quality of life. A portion of your purchase will be donated to Sightsavers, to fight blindness worldwide.
Sightsavers is an international non-governmental organization which works with partners in developing countries to treat and prevent avoidable blindness and promotes equality for people with visual impairments and other disabilities.

There are 39 million blind people in the world, but 80 percent of blindness can be cured or prevented. That’s 31.2 million people who are blind when they needn’t be.

About Sightsavers

(From Wikipedia)
Sightsavers is based in Haywards Heath in the United Kingdom, with branches in Sweden, Norway, India, Italy, Republic of Ireland, the United Arab Emirates, and the USA.

The charity was founded in 1950 by Sir John Wilson and was originally called the British Empire Society for the Blind, then the Royal Commonwealth Society for the Blind. Its patron is HRH Princess Alexandra. In its 65 year history, Sightsavers has distributed treatment to protect more than 295 million people against river blindness (onchocerciasis), carried out 6.1 million sight-restoring cataract operations and treated 43 million people with antibiotics to combat the potentially blinding infection trachoma.

In November 2016, charity evaluator GiveWell included Sightsavers in its list of top charities for that year, for the organization's work on deworming programs, and published a review of the Sightsavers' work on that front.
