The unique advantages of PARKS blue light filtering lenses
| General reflective blue light filters typically have only a single layer of coating, which can filter out approximately 10% of blue light (average blue light filtering rate), while maintaining a 95% light transmission rate. However, a 10% filtering rate is relatively low. |
General absorptive blue light filters typically absorb 30% to 50% of blue light (average blue light filtering rate). However, their light transmission rate is only 60% to 70%, which is relatively low. This reduced light transmission can potentially contribute to or worsen nearsightedness. |
PARKS Blue Light Filtering Lenses
PARKS blue light filtering lenses effectively filter out 60% to 90% of strong blue light. They offer a higher balance of light transmission and blue light filtering rate, making them an optimal choice for blue light glasses. The filtering rate for strong blue light is approximately 60% in the 380–460 nm range, with a light transmission rate of about 93%. |

How to Choose Good Blue Light Filtering Glasses
-
1.Both Blue Light Filtering Rate and Light Transmission Rate Should Be High
- If only the blue light filtering rate is emphasized, the lens color may be too dark, increasing eye strain and potentially worsening nearsightedness.
- Some lenses may appear overly transparent, but if the blue light coating is inadequate, it may not provide sufficient protection for those who use smartphones or are exposed to LED light sources for extended periods.
- ※Typically, a blue light filtering rate of over 50% from 380 nm to 470 nm is ideal, with at least 25% blocking at 450 nm where LED blue light is strongest.
The light transmission rate should be over 85%.
- 2. The Lenses Should Have Third-Party Objective Certification and Clearly Display Blue Light Blocking Rates for Each Wavelength Range
