The Market - Are All Blue Light Blocking Glasses The Same?
The answer quite bluntly is: "No, they are not!"
The ultimate purpose of blue light blocking glasses is to protect our eyes from the hazardous blue light with wavelength from 400-500 nanometers (nm). Not more and not less!
We have measured the blue light blocking performance of various glasses in the market with a BPI UV & Blue Light Analyzer, which is a specialist laboratory equipment designed to measure the blue light transmittance of a lens at various points in the blue light spectrum. These measure points are at 400nm, 430nm, 470nm and 505nm.
Our analysis has shown that in terms of blue light blocking performance three of the tested glasses brands already fall quite significantly short at 430m, while another two brands take a performance dip at 470nm. This leaves a group of only three brands consistently performing at the highest level across the whole blue light spectrum.
Test Result Data
These analytics confirm the opening statement of this paragraph that blue blocking glasses are simply not all the same. While most of them advertise to have more or less the same functionality and benefits, as a matter of fact some of the glasses are way more effective in blocking blue light than others. Having a great sales pitch is one thing, but backing it up with correspondingly high quality and functionality is obviously something different.
We strongly believe in top quality standards and employ a rigorous quality assurance process to ensure that Your SUBLIME BLUE LIGHT BLOCKING GLASSES are of high quality and fit for purpose.
