yes some lasers would if you shine them in your eye, the energy will burn your retina and destroy the cells that pick up light that you use to see, of course lasers can also help people improve their sight when used properly by a doctor!

yes, it can do. There are lasers and certain lights that you should never look at directly because it will permanently damage your eye-sight. You should never look directly at the sun, and don’t shine laser pointers at people’s eyes.

They can do – it depends on their power and their wavelength. Visible lasers are very dangerous for the retina – back of the eye and especially the part of the eye called the fovea – which is responsible for detailed vision – like when you are reading. Damage here can cause you considerable problems. UV lasers are more likely to damage the lens (the focusing part of the eye) whilst infra red are likely to damage the cornea. As I said this really depends on the power of the laser, but a good rule is never look directly into the beam of a laser.
