Interactive Twitter visualisation maps UK eyesight

TwitterVision is a novel research project commissioned by UK laser eye surgery specialists Ultralase which aims to reveal the state of the nation’s eyesight using Twitter to plot people’s eye prescriptions.

The application merges user-submitted prescription data from structured tweets with Ultralase’s own in-house data, in order to visualise the UK’s eyesight quality in an intuitive and original way. The interactive allows you to zoom in and check out the eyesight from your postcode and compare the patterns across the country.
Ultralase is also donating 10p for every relevant tweet to the charity Vision Aid Overseas to help raise funds for a project in Uganda. You can find more information about the project here.
