| Physical Filters | Screen covers or glasses that block blue light physically. | Works on all devices, no battery needed. | Can reduce screen brightness, may change colors. |
| Software Solutions | Apps or built-in settings that adjust screen colors. | Easy to enable, no extra hardware needed. | Only works on the device, may alter color accuracy. |
- Common technologiesinclude tinted glass, special films, and color filters.
- Software often uses warm color tonesto reduce blue light.
- Some filters combine both physical and software features for better results.
