If a LASER device burned you retina, you would mostly or completely blind in that eye. There would most likely be no way to repair the damage. Keep in mind that LASER beams can cut through steel !
if it was twice as massive, earth probably have burned, noone would be here, and surviving would be a 1 out of 100,000
An eye doctor would need to measure the distance to the retina to correct nearsightedness or farsightedness. Nearsightedness occurs when the focal point of light falls short of the retina, so the goal is to adjust the focus point onto the retina. Farsightedness happens when the focal point falls beyond the retina, so the focus point needs to be moved closer to the retina.
Yes. The moon's high albedo is used as a mirror to reflect laser light from the Earth. They more accurately track the orbit and distance of the moon than previous methods. However, in order to have a reflected laser beam that the eye could see (like in a movie) the laser would have to be incredibly strong and have a large beam. No laser currently on Earth is capable of this. However, the moon's albedo is high enough that if such a significantly large laser existed it could reach the moon and be reflected back.
nothing would happen
There are many benefits associated with using a laser scanning confocal microscope. The main advantage is to obtain pictures one would not normally be able to receive at such depths.
They would get burned.
Yes, laser lights can potentially damage the eyes if they are powerful enough and focused directly into the eyes. Exposure to high intensity laser light can cause vision impairment or even permanent damage to the retina. It is important to use caution and protective eyewear when working with lasers to prevent eye injuries.
You would have your mouth burned, or would be tortured.
Very, very small
The earth would be destroyed
They are pickpockets, they would be burned at the stake.
If we had no lens in our eyes, the light entering our eye would not be focused onto the retina, causing blurred vision. The lens plays a vital role in adjusting the focus of incoming light to create a clear image on the retina.
you will most likely get burned
You would lack the ability to "see" many colors. You would also lose a significant amount of your visual acuity.
It would depend on what is in the syringe. If it contained water then you would get wet. If it contained sulphuric acid you would get burned
that black powder is called carbon
if it was twice as massive, earth probably have burned, noone would be here, and surviving would be a 1 out of 100,000
