Staying healthy

10. Ensuring good eyesight

Problems with eyesight can increase confusion in people with dementia, and can make it harder for them to recognise people or objects. Optometrists have special techniques for assessing sight, even for people in the later stages of dementia. They should also check for cataracts and glaucoma (both of which can lead to blindness if left untreated), as well as for certain other medical conditions.

If someone with dementia has sight problems, you may need to tactfully remind them to wear their glasses and check that their lenses are clean.
