Children tend to spend more time outdoor than adults, so it is imperative they have sunglasses to protect their eyes from the harmful effect of the sun. Long exposure to UV and high-energy visible (blue light) have been shown to increase age related eye problems. Children are more vulnerable to retinal damage from UV rays because the lens inside a child’s eye is clearer than an adult lens, enabling more UV to penetrate deep into the eye. It is important for all children, even infants, to wear UV- and HEV-blocking sunglasses anytime they are outdoors in daylight hours. It is also recommended during cloudy or overcast days, since UV rays are invisible and go through cloud covers. You may be asking what sunglasses I should purchase. Children’s sunglasses should block 99 to 100 percent of both types of ultraviolet rays: UVA and UVB.
When purchasing children sunglasses make sure they have a polycarbonate lenses. This is recommend for children since they are impact resistant and they are lighter than glass or standard plastic lens. Also make sure the frame is a large close fitting frame. I would also recommend unbreakable frame material and frames that have spring hinges that can extend beyond 90 degrees and spring action that will ensure a snug fit. Finally I would recommend a frame with an elastic band, this helps prevent lost or damage sunglasses and it can also help with a secure fit to the child’s face. Do not invest an inexpensive pair of children’s sunglasses since the material may not be as durable as quality pair of sunglasses.
