Question

which laser consider eye safe​

Answer 1

Answer:

Lasers with emission wavelengths longer than ≈ 1.4 μm are often called “eye-safe”, because light in that wavelength range is strongly absorbed in the eye's cornea and lens and therefore cannot reach the significantly more sensitive retina.
