Join me as I try on some Warby Parker glasses at home and let the kids have their say. Since I get so much blue light via so much screen time, it's time I take action.

What does blue light do to your eyes?
Blue light is everywhere, and it can throw off our natural body clocks.
“We get constant exposure to blue light from ambient sunlight, computer screens, tablets and mobile phones,” said Dr. Rohit Varma, MD, MPH, founding director of Southern California Eyecare and Vision Research Institute.
“The brain associates blue light as daytime, so if a person is exposed to blue light for long periods of time during the night, blue light makes it more difficult for us to fall asleep at night and wake up in the morning,” Varma said.
While there’s no definitive information on the exact amount of blue light you can be exposed to before showing serious side effects, “long-term exposure to screen light can have some intense serious side effects,” said Caroline Dubreuil, product marketing manager for EyeBuyDirect.
“Headaches, disorientation and loss of sleep are just the start of it” said Dubreuil, whose website, like many eyewear retailers, sells blue light blocking glasses

All that screen time may be causing digital eye strain.
“There are many causes for eye strain,” said Dr. Raj K. Maturi, MD, a spokesman for the American Academy of Ophthalmology. “Blue light is just one of them.”
Maturi said being too close to your screen doesn’t help: “We strain our eye muscles when looking at such a close target.”
Late-night screen time throws off sleep patterns, because blue light affects melatonin (the sleep hormone) levels.
How? Decreased light at night signals the body to generate sleep hormones like melatonin. Blue light disrupts these signals, and less melatonin is generated.
For some, blue light filtering glasses are a great way to combat the eye strain and sleeplessness that come with excessive screen time.
