There are many blue light blocking glasses available on the market making all sorts of different claims. We know that this can make purchasing a quality pair overwhelming and very confusing!
A lot of the orange or red-tinted glasses being sold are just simply that, red and orange-tinted. Often suppliers have not properly designed the lens to ensure it is actually blocking the correct wavelengths of blue light, with no research or testing in these products' development. If this is the case, you aren't likely to notice any significant changes or benefits from these types of lenses.
Many other brands of glasses are being sold that have clear lenses yet are still claiming to block various sources of blue light. Typically, these lenses are really only filtering out very small amounts of harmful light. Clear lens glasses will only really be capable of filtering around 10% - 20% of blue light - slightly beneficial for eye strain but they will not have any benefits in preserving melatonin and improving quality of sleep.
All of BlockBlueLight's glasses have been extensively researched, scientifically designed and manufactured specifically using the best technology to ensure ALL of the wavelengths of harmful blue and green light are both being removed.
We have our lenses tested by a laboratory grade spectrometer to ensure we are producing the very best lenses which effectively block all blue light. You can see our lens testing reports to see how much light is being blocked. We are confident that you won't find better quality blue light blocking glasses on the market.
We have designed our glasses to have a wrap-around fit to ensure there is no light leakage coming in from the sides and still entering the eye - this is critical to ensure the glasses remain effective at blocking out all artificial light. Many glasses are simply focused on fashion and style of their frames but not focused on blocking harmful artificial light to promote improved sleep. Don't be fooled by expensive blue blocker glasses that may look good, as they are most likely doing a very poor job at both blocking the correct wavelengths of blue light, and keeping the harmful blue light from still entering your eyes through the sides!
