Vision Aid Overseas run a programme, Helping the world to see, which accepts old (but not broken or damaged) spectacles.
All of our recycling centres provide containers where you can deposit used spectacles.
The Recycle Now website offers advice on donating hearing aids and hearing aid batteries to charities such as Help the Aged, Age Concern and The Lions Club. These are repaired, refurbished and sent overseas for reuse in developing countries.
Hearing aid batteries can be treated in the same way as other batteries.
