Girls Cute Heart Shaped Sunglasses

No. UV400 and polarization describe two different lens features. UV400 refers to ultraviolet protection, while polarized lenses are designed to reduce certain types of reflected glare. A pair of sunglasses can have UV400 protection without being polarized. These sunglasses are listed with UV400 lenses, but the product does not claim polarized lenses.

Frame shape by itself does not determine UV protection. The lens UV rating is what tells you about ultraviolet filtering, while the size and fit of the frame affect how much area around the eyes is physically covered. Heart-shaped sunglasses can still provide UV protection when the lenses carry an appropriate rating, but they should also fit securely and cover the eyes properly. These heart-shaped sunglasses are listed with UV400 lenses.

A sun hat and sunglasses do different jobs and can be used together. A brim helps shade the face and eyes from some direct sunlight, while UV-rated sunglasses provide additional protection through the lenses. A hat does not block every angle of light, so wearing both can provide more complete coverage during sunny outdoor activities. For children in the appropriate age range, you can also pair these sunglasses with our Willow Ribbon Girls Straw Sun Hat.

Replace kids' sunglasses when the lenses become heavily scratched, the frame is cracked or bent, the arms become too loose to stay in place, or the glasses no longer fit comfortably as the child grows. Small cosmetic marks do not always mean the sunglasses need immediate replacement, but damage that affects vision, fit, or the integrity of the lenses and frame is a good reason to stop using them.
