Doggles was developed by the Doggles founders after they noticed that their dog had difficulty playing fetch in sunlight. They would often squint and miss the ball. This idea would grow into a $3,000,000 company (and is still growing).

Doggles are dog sunglasses. According to Outside Online,older canines with cataracts due to age-related disabilities would have “slightly improved” vision on a sunny day if they wore Doggles. Doggles is now available in a variety of pet products, including carriers, bowls and beds.
