I look right into it, and others I've discussed this with online do also. Between 8-9AM, and for me I do it 3X a week, I do each eye for 3 minutes. I have only used it a short time, so I can't give a report yet, but It does feel good to do it. **Q: Can the brightness level be adjusted? I'm concerned that this light may be too bright to look at.** A: The brightness cannot be adjusted, but the farther away you hold it, the lower the energy at the target will be. You can also add a diffuser to reduce the energy. You can purchase a diffuser, or look into scotch tape or teflon tape as an option. Search "diffuser vs scotch tape" online. **Q: How do i use this " torch-like tube" to "emit energy equivalent to 40 mW/cm2 or 4.8J/ cm2 for 2 min" ???** A: 1.21 Jigga watts in a tri-phase capacitor, with a velocity at 88 mph. See you in the future! The answer is 42! **Q: This gets really hot. It has only been on a few minutes. I can hardly hold it. Is this normal?** A: The previous version of the flashlight occasionally had this issue. Our new updated model does not get hot. Please message us and we will send you the new version. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent *by F***H on 6 November 2025* Excellent have been using this every day for 4 months and have noticed my close vision had improved a lot ### ⭐⭐⭐⭐ Not sure it helps *by A***R on 30 December 2025* Torch worked fine ### ⭐ Dont waste your money *by D***. on 5 August 2025* Bought this torch specifically because of its Red 670 nanometer output.
