Blue blocker bullsh*t - clear lenses, scam?
Are all blue blockers equally beneficial in their function? No.
In fact, the majority of blue blockers that you see on the market are a total waste of money and borderline deceitful in their marketing strategy. Whether these companies are knowlingly selling you a false-product or their just not well-versed in the science behind blue blockers and what they do is another question for another time. What we do know for certain is they they use a clever trick to make you believe that the blue blockers you just purchased are any bit of blue-blocking.
You can look at a pair of blue blockers and know immediately that they're not going to work based on the color of the lens. This is because different color lenses will absorb a greater or lesser degree of blue light. "Blue blocker" lenses range from faint yellow, yellow, orange, and red. Can you guess which pair block the greatest amount of blue light?
As mentioned in previous blogs, in order for a pair of blue blockers to be effective they have to block all light up to a specific wavelength because the "blue light sensors" in our eyes (melanopsin) don't just respond to blue light only, but a little bit of green light as well. Those clear, faint yellow, and yellow pairs don't even come close to being useful for nighttime. Whats even worse is how these companies and entrepreneurs take advantage of a trend by selling you something they A. know nothing about, and B. may or may not know is actually true or useful.\
If you want to absolutely make sure that the pair of blue blockers you're wearing protect your melanopsin sensors (imperative) and keep you from experiencing all the negative effects from artificial blue-light exposure as mentioned HERE, they have to block all light up to 550nm. Our nighttime lenses do exactly that, they cover the full range of light which our melanopsin sensors respond to.
If the pair of "blue-blockers" you've purchased don't block up to 550nm, you're better off using them for daytime use for situations like being inside on a computer. Other than that, they don't have much use at all.
What is the trick these companies use to make us believe they block blue light? Watch as Dr. Anthony G. Beck explains in this short video below.
In short, the test card and "blue light" you've been given with your purchase of those cheap blue blockers is not actually a blue light.. its VIOLET! It is a complete scam, the card with its photosensitive ink is responding to violet light, not blue. Those blue blockers do not block any blue light at all.
