The Royal National Institute of Blind People (RNIB) is heading to Glastonbury to raise awareness of eye health.

Revellers at the festival will be offered the chance to belt out their favourite tunes by taking part in the Karaoke Eye Test.

The twist is that the lyrics on the screen will gradually get smaller as the song progresses, just as the letters would in a typical eye test.

Filters that simulate the effects of ocular conditions such as age-related macular degeneration and glaucoma will also be added to the screen as they sing.

After they have sung, participants will be given advice on how to look after their eyes and encouraged to get eye tests every two years.

Sally Harvey, Chief Executive of the RNIB, believes this is an innovative way to raise awareness of eye health.

“The RNIB Karaoke Eye Test is a brilliantly fun, interactive idea to turn heads and draw crowds at Glastonbury, all while tapping into the sights, sounds and general ethos of the festival,” she commented.

“It’s a fantastic and memorable way of getting a whole new audience of Glastonbury-goers on board with our mission of improving the eye health of the nation.”

Ms Harvey said the Karaoke Eye Test will also help to remind people of the importance of having regular eye tests.

She added that since Glastonbury is such an iconic festival, the charity is “excited to be part of the line-up for 2017.”
