My best anti-aging habit (one which I try to pass on as often as possible) is definitely getting my eyes tested regularly. I work at RNIB (Royal National Institute if Blind People) so know the importance of getting my tested regularly. There are some conditions like glaucoma that have no symptoms and so can result in sight-loss without you realising! You can actually lose up to 40% of your eyesight before you notice.

A quick visit to your local optician can ensure your eyes are as healthy as they seems. They can also answer any questions you may have, or you could always check the RNIB website for more information - http://www.rnib.org.uk/happyeye
