Last year the Brighouse branch of Specsavers collected 2,500 old glasses frames donated by customers for its Vision Aid Overseas appeal.
Now Brighouse people are asked to do their bit again to support the international charity’s work in developing countries.
The glasses are recycled and the money raised is used to give people badly-needed eye tests and treatment and training optometrists.
Gareth Hart, at Specsavers in Commercial Street, said: “There must be thousands of pairs of spare specs lying around in drawers around the country that are no longer of use to their owners. All donations are welcome.
“It is it important that we do what we can to improve health care elsewhere.”
Specsavers has worked closely with Vision Aid Overseas for the last decade, raising more than £370,000 and collecting more than 250,000 pairs of glasses.
The money has been put to good use by funding the construction of a school for optometry in Zambia’s capital, Lusaka, and two vision centres in the country’s Central and Luapula provinces.
The charity aims to add six more vision centres by 2015 so that there is one in each province of the African country.
