These Blue Light-Blocking Sunscreens Protect You From Your Phone

How good are you at remembering to wear sunscreen? Turns out, there might be another wavelength of light you should be concerned about. "Consumers mostly know only about UVA and UVB light, but HEV (blue light) also exists," says Dr. Sameer Bashey, a board-certified dermatologist at the ZO Skin Centre. "This light comes from the sun but can also be emitted from phones, tablets and computer screens."

Though he notes that the evidence is still unclear on the exact effects HEV light has on skin (not to mention, your vision), he says that it's likely similar to what UVA and UVB do — namely, causing inflammation and free radical damage, as well as hyperpigmentation and brown spots. "It may potentially be worse than UVA and UVB, as it can penetrate deeper into the hypodermis," he adds.

So, what's your best bet for protecting yourself? Well, as Dr. Bashey explains, not all sunscreens include blue light in their standard broad-spectrum UVA/UVB coverage. "Zinc- and titanium dioxide-based sunscreens can reflect some portions of HEV light, but not all," he says. Your best bet is to look for products specifically designed to block blue light — like the ones rounded up here. Keep reading for our top picks.
