What is the least hazardous danger of viewing a laser beam?

Explanation:
When evaluating how dangerous it is to view a laser, what matters is how much light actually reaches the eye. Diffuse reflection scatters photons in many directions, so the energy entering your retina from any single viewing angle is greatly reduced, making it the least hazardous option. Intrabeam viewing means looking straight along the beam, delivering concentrated power directly to the retina and posing a high risk. Specular reflection from a smooth surface can send a bright, focused beam into your eye, retaining much of the original power and creating a serious hazard. Absorption by a surface reduces the light that is reflected toward the eye, so it generally presents less risk for viewing.
