OcularCheck

Accessible, free, & accurate visual acuity examinations

Today, over 2 billion people suffer from visual impairments due to the lack of access of affordable and accurate screening methods, as well as lack of awareness about the issue. OcularCheck lets you detect myopia and other visual impairments right from home so that you can seek professional care.

OcularCheck is the ONLY distance visual acuity exam app that is clinically validated by research, available cross-platform, and extremely accessible. It has been developed for use in underserved/rural areas of the world, including features such as: diagnostic accuracy, no internet requirements, auditory guides, extremely wide device compatibility, and multilingual optotypes, and more. These features allow OcularCheck to play a unique role in the international public health community.
