What blue-light blocking glasses cannot do
Standard blue-light blocking glasses do not offer any form of magnification. This makes them perfect for people who do not wear prescription glasses. For those who do wear prescription glasses, it is possible to have blue light filtering added at the point of manufacture, but not after.
Blue-light blocking glasses cannot remove digital eye strain completely. Lessening your screen time is preferred, but not always possible. When looking at your screen for long periods of time, it is advised that you follow the 20-20-20 rule. Every 20 minutes, look at an object 20 feet (6 metres) away for at least 20 seconds.
So blue-light blocking glasses do what they say, but do we really need them?
As mentioned, we don’t yet know the true extent of artificial blue light damage over time. But many have turned to blue-light blocking glasses as a preventive measure, based on what we do know about the harmful effects of blue light in general.
While more scientific research would certainly be helpful, there are thousands of positive personal accounts from people using blue-light blocking glasses. First-hand benefits listed include improved eye comfort, less strain, less dryness and redness, less eye fatigue, fewer headaches and improved sleep.
Studies have also proven that the use of blue-light blocking glasses does increase melatonin production at night, which leads to better sleep and all the benefits that come with it.
Are blue light blocking glasses right for you?
Do you spend lengthy amounts of time looking at screens? Can you use your devices without prescription glasses? Do the above-mentioned benefits sound appealing to you? If yes, then give blue-light blocking glasses a try. There are no known risks associated with wearing them.
