how does one expose their eyes to light in that spectrum safely?
- copperx 5y agoI do not understand the assumptions behind this question. Can you clarify what you mean?
- baq 5y agoIs a red bulb enough or do you need a 670nm laser?
- tlrobinson 5y agoI hope this was a joke. Don’t shine lasers in your eyes. https://en.wikipedia.org/wiki/Laser_safety https://en.wikipedia.org/wiki/Laser_safety
- flyinglizard 5y agoFor the love of all that’s dear in this world, please don’t use a laser for that. If you’re in a DIY mood, you can easily pick LEDs around that wavelength and they would generate more than enough light to even cause damage (if close enough).
- andrew_ 5y agowhat assumptions? it was an honest question.
- webmobdev 5y agoThe safest way to do this is to step out in daylight when the sun is bright. Take a brief walk. You will also get a boost of Vitamin D that will cheer you up. Interestingly, in Yoga there is a pose called surya namaskar (salutation to the sun) that is supposed to be done early morning when the sun rises.
