How can I protect my eyes from blue light at night?
Computer glasses: Computer glasses with yellow-tinted lenses that block blue light can help ease computer digital eye strain by increasing contrast. Anti-reflective lenses: Anti-reflective lenses reduce glare and increase contrast and also block blue light from the sun and digital devices.
Is blue light bad for your skin?

Does blue light actually whiten teeth?
LED (light-emitting diode) produces blue light to increase the teeth whitening process without any radiating heat to the teeth. Most over-the-counter tooth whitening kits with lights contain LED products – although dentists might use LED blue light, as well.

Does blue light break down collagen?
While ultraviolet light damages cells’ DNA directly, blue light destroys collagen through oxidative stress. A chemical in skin called flavin absorbs blue light.
What blocks blue light on skin?
Marmur says that anything with zinc oxide can also protect against blue-light damage. The UV Clear version has zinc oxide along with niacinamide, hyaluronic acid, and lactic acid, which are ideal for calming acne-prone skin and those with rosacea or hyperpigmentation.
Does blue light cause dark circles?
Studies suggest that blue light exposure could be the leading cause of premature ageing and dark circles around the eyes.
Does LED light really help whiten teeth?
LED lights are used in teeth whitening procedures for one key reason: research has shown they speed up the chemical reactions that remove the stains from teeth. Overall, the addition of LED lights to whitening procedures has improved the effectiveness of whitening agents, allowing for brighter and whiter smiles.
Are LED teeth whitening kits bad?
Is teeth whitening healthy?

Does blue light make you age faster?
Daily exposure to blue light may accelerate aging, even if it doesn’t reach your eyes. Summary: New research suggests that the blue wavelengths produced by light-emitting diodes damage cells in the brain as well as retinas, according to a new study in a model organism.
Does blue light affect memory?
Hence blue light exposure affects the ability to hold information in mind and interferes with short term memory. In sustained attention task reaction time of LED screen participants was slower than blue light filter screen participants. Therefore, blue light exposure disrupts the ability to focus on a single task.
Can blue light damage the brain?
Long-term exposure to blue light emitted by smartphones, laptops and other digital devices may lead to brain damage and speed up the ageing process, scientists say.
