With regard to the eye health of younger individuals, children specifically, the NHS recommends that parents should look out for a number of hints.

These include whether their child is sitting too close to the TV, holding objects very close to their face, blinking a lot, eye rubbing, one eye turning in or out, and a white reflection in their pupil.

Other risk factors for poor eye health include smoking.

The NHS says: “If you smoke you’re much more likely to develop age-related macular degeneration, which is the most common cause of sight loss in the UK, and cataracts, than people who do not smoke.”
