Do your children's sunglasses really expire? Short answer is yes, here's why: Over the last decade UV protection for your skin and eyes has become common knowledge but recently there has been new information about our favourite UV protection gear, kids sunglasses! Similar to other UV protection products like sun block, a new 2016 Brazilian study suggests that sunglasses do expire. Yes, you heard that right --- sunglasses actually expire! The study shows that over time sunglass lenses can lose effectiveness in blocking out UV rays. Normal wear and improper cleaning causes very small scratches on the lenses. These scratches, even ones not visible while you are wearing them, reduce the lenses ability to provide proper UV protection. This is very relevant information for children’s sunglasses. Kids tend to be quite rough on their belongings --- glasses get scratched and tossed around in their backpacks more often than not. So it’s a good idea to splurge on a new pair of shades every couple of years to keep their eyes protected.
Not ready to buy new glasses just yet? Teach your children how to take care of their eyewear so they last longer!
1. Keeping sunglasses safe in a soft or hard case
Explain to your kids about the importance of keeping the lens safe so they don’t get scratched. They are the most important and most fragile part of the sunglasses. Teach your children to put them back in the case before tossing them in their backpack.
2. Use a microfibre cleaning cloth to wipe lenses
Show them how to properly clean the sunglasses when they are dirty. It’s easy to wipe the glasses with your shirttail or napkins but using these types of cloths leave tiny scratches on the lenses. Use a microfibre cloth and lens cleaner or a small drop of dish soap and lukewarm water. Don’t use glass cleaners like Windex or other household cleaners to clean the eyeglasses. These types of products typically have ingredients that strip off coating.
3. Set a good example!
If they see their parents using their shirttail to wipe their glasses or throw glasses into their purse without a case they’ll probably do the same. Children watch and imitate, so set a good example. Good habits will save you money!
