People who want to keep their brains sharp have been advised to get regular eye check-ups.
Mehmet Oz and Michael Roizen, in an article for the Vancouver Sun, recommended that people need to have sharp eyesight if they want to avoid Alzheimer"s disease and other forms of dementia.
Check-ups will help people identify any eye problems such as cataracts and glaucoma that can get in the way of having decent eyesight, the experts advised.
In other recommendations, they said that blood pressure needs to be kept at a healthy level if people want to stay mentally quick, as high blood pressure leads to microscopic scarring in the brain.
This leads to damage being caused to "tiny arteries that supply blood to the network of nerve fibres that brain cells use as a communication system".
Kate Fielding, director of communications and information for the General Optical Council, recently advocated regular eye checks and said that they should not be ignored by those who do not wear glasses or contact lenses.
