Dr Michael Jones, a paediatric ophthalmologist from The Sydney Eye Hospital shares his answer.
"Wearing sunglasses as a youngster can help protect against the most common eye conditions that develop later in life.
We tend to forget that a lot of our sun exposure happens when we are children, when we spend a lot of time outdoors in direct sunlight, Jones says.
You don't have to spend a fortune buying sunglasses for your children, just ensure the pair you choose have standard UV 400 lenses or 100% UV protection.
Novelty sunglasses with coloured lenses aren't a good idea because they don't provide as much protection, he says.
Putting sunglasses on your kids should be part of the everyday sun protection routine, Jones says."
"According to the World Health Organisation (WHO), children’s eyes are more sensitive to UV absorption and up to 80 percent of a person's lifetime exposure to UV will occur before the age of 18.
Sun damage to the eye is linked to serious problems such as age-related macular degeneration (AMD), which is the leading cause of irreversible blindness in the industrial world, as well as cataracts (cloudiness of the lens) and pterygia (benign growths on the white of the eye, which can end up blocking vision)."
