Homeless charity Crisis at Christmas has appealed for the loan of mobile optometry kits for its Vision Care for Homeless People initiative.
The scheme, which provides a comprehensive service in London, will run for a week starting on December 21.
Last year the charity provided sight tests and glasses for a record 363 people during the week.
Permanent replacements of field screeners in London and Birmingham clinics are also needed.
Charity chair Elaine Styles said: ‘We are still using Henson 3000s and would ideally like to replace them with Henson 6000, 7000 or 8000 models. Having new machines would mean that our clinics could run more efficiently and would be more accurate for health screening.’
