New visual impairment calculations to assess economic burden

New visual impairment calculations to assess economic burden

The economic burden of visual impairment is to be highlighted in new guidelines which will affect contact lens wearers across the world.

A new study published by the International Agency for the Prevention of Blindness in the journal Investigative Ophthalmology and Visual Science suggests that accurately calculating the economic burden of visual impairment can have a positive effect on every country.

Dr Kevin Frick, lead author of the study and a Johns Hopkins University researcher, said that if every nation uses the same method to generate cost estimates, it will make it easier for the scientific and medical communities to draw accurate conclusions and compare results across studies.

"When estimates of the cost of visual impairment vary over time or across countries, policymakers are left to ponder whether one estimate differs from another because of changes in the population, impact of the disease and methods," he said.

The potential social impact of poor eyesight was recently highlighted after a council-led operation in Hemel Hempstead found two taxi drivers with poor eyesight.
