Are they just hype?
Is it worth the extra money?
The American Academy of Ophthalmology (AAO) says you don’t need them and has gone on record as not recommending any kind of special eyewear for computer users. The organisation says blue light from digital devices does not lead to eye disease and doesn’t even cause eyestrain. The problems people complain about are simply caused by overuse of digital devices, it says.
“The symptoms of digital eye strain are linked to how we use our digital devices, not the blue light coming out of them,” the AAO says.
What blue light does is that affects your brain’s production of melatonin. Melatonin is important for good sleep so yes, screen time before bed does affect your quality of sleep. Turning on the blue light filter from the source (phones, ipads, computers) is much more effective than blue light glasses.
If you want to avoid digital eye strain remember to take breaks every 20 minutes and turn to an activity that rests your eyes by not focussing on near things. You can turn down the brightness or add a dark chrome reader which you would have seen if you have been to my consult room to see my computer.
So save your money on blue light glasses, nothing beats eye breaks!
