Unique Advantages of PARKS Blue Light Filtering Lenses

Conventional reflective blue light filtering lenses usually have only one layer of coating, so they can only filter out about 10% of blue light (average blue light filtering rate), but have a transmittance of 95%. The blue light filtering rate is too low.	Conventional absorbing blue light filtering lenses absorb 30%-50% of blue light (average blue light filtering rate), but have a transmittance of only 60%-70%, which is too low and can cause or worsen myopia. The transmittance of 60%-70% is too low.	PARKS 濾藍光片 PARKS 濾藍光片，可有效過濾強藍光60%~90%。透視率、濾藍光率變高，是濾藍光眼鏡的最佳選擇。濾強藍光率約60%380-460mm透視率約93%

SGS Report

Wavelength Range	Average Blocking Rate	Average Transmittance
280~380nm Ultraviolet	100%	0.00%
380~470nm Strong Blue Light	57.89%	42.11%
470~500nm Weak Blue Light	17.42%	82.58%
500~780nm	5.56%	94.44%

How to Choose Good Blue Light Filtering Glasses

Both the blue light filtering rate and transmittance should be high.
If only the blue light filtering rate is emphasized, the lens color will be too dark, increasing the burden on the eyes and promoting myopia. Some lenses are too transparent. Although they have a blue coating, the coating layer is insufficient, which may provide inadequate protection for modern people who use mobile phones and LED light sources for a long time.
※Generally, the blue light filtering rate is more than 50% for the range of 380nm to 470nm, especially at 450nm where LED blue light is strongest, there is a blocking of more than 25%.
The transmittance should be above 85%.
The lenses should have third-party objective certification, and the blue light blocking rate for each segment should be clearly indicated.

Why PARKS is a good choice for blue light filtering glasses

High blue light filtering rate and transmittance, for example:
60% lens - filters 57.89% of strong blue light, transmittance of 92%
70% lens - filters 65% of strong blue light, transmittance of 90%
80% lens - filters 85% of strong blue light, transmittance of 80%
90% lens - filters 92% of strong blue light, transmittance of 40%
100% lens - filters 100% of strong blue light, transmittance of 20%
Complete specifications suitable for different personal situations and eye conditions. There are 5 lens specifications ranging from 60% to 100%.
Certification is transparent and publicly available.
