Optometry NI says 'half of all cases of sight loss avoidable'

Half of all cases of sight loss are avoidable according to the local association of optometrists, Optometry NI, which has urged the public not to ignore routine eye tests.

One man, Jason Scoltock, 46, was diagnosed with a blood clot after it was discovered by his optician during an examination.
