LIGHTBENDERS BLUE BLOCK BRIL
These glasses filter the harmful blue light to which you are exposed, for example, when you have white LED lighting in your home or look at the screen of your phone or computer or TV. By filtering this harmful light you maintain a better sleep rhythm and more energy.
These glasses have yellow, orange or red filters that filter out most blue and green light. For examples and explanations you can read the Specifications tab. In the video (video tab) you can also see how much the glasses can filter per color in blue and green light.
Model
Full frame transparent + glass color of your choice.
Material
PC (polycarbonate)
Why are the glasses not made of real glass? Real glass has slightly better transparency, so even clearer vision, but a poor ability to filter the desired colors. For this, PC layers would still have to be made in the glass. While the glass is more fragile and more expensive. There are almost no factories left that want to work with glass for this application.
If you want quality glass glasses without these filters, then these glasses are not for you.
Specifications
Each color has its specific qualities, from transparent to red the blue and then also green light is increasingly filtered.
Below you can see measurements that we have taken ourselves and because we test the glasses in the open air, there is minimal reflection of the ambient light, which is even less on the face.
Color measurement
These tests were done hands-on and closer to the screen than your eyes would be. The exact light intensity numbers are therefore not important because we look here at which colors are filtered and in what ratio.
Color measurement of monitor
Monitor colors according to our photo spectrometer without filter
Transparent glasses
Transparent glasses are often called computer glasses because everything apparently remains normal, but there is already a light filtering that can give rest to the eyes. Transparent glasses are not suitable for nighttime sleep.
Blue is still clearly visible (lower intensity) and part has shifted to green-red
Yellow glasses
Yellow is often used for night blindness, driving in the dark or as they usually put it in English 'night driving' because significant filtering takes place but enough light still comes in to drive safely. We therefore advise not to drive in the dark with orange or red glasses.
heavy blue filtering and shift to green - red.
Orange glasses
Orange lenses are my personal preference because they completely filter out the blue, but with the green and red that remain, they still provide some color sensation and clear vision.
Blue completely filtered and green already largely shifted to red.
Red glasses
Red is most commonly seen in the world of biohacking, red filters both blue light and green light, leaving only red light. This gives the best results that biohackers look for.
Blue and green filtered leaving only red. Keep in mind the first photo, the tiny remnant of blue and green is reflection in the open sky.
