Do snipers keep their eyes open when they shoot?

This is a very good question because it involves the use of scope. Snipers are not the only ones who use sights. If you are a biologist, you will often use a microscope. If you like watching stars (astronomers), you can use a telescope. Of course, even professional photographers can use sights, so there will be the same problem.

I don't even know if the sniper will open his eyes because he hasn't fired a gun. But I know the other three uses of the scope I mentioned. Honestly. Everyone has his own opinion.

For astronomers, it is usually practical to close their eyes, because they usually observe objects in a dark space. If you want to see some nebulae a few light years away, even a small light in the room will distract the other eye.

So, to solve this problem, you just need to work in a dark room, put on an eye patch or close your other eye. But generally speaking, in the observation room, the room is generally dark, so you can keep your eyes open. Because, as many answers show, it will relieve the pressure on your eyes and facial muscles. But eye patches are often used. In addition, when operating in the dark, they often use a red flashlight because your retina can't see red light. )

For photographers, it usually depends on their training and experience, but it is often a natural habit to close one eye, because when you look at an object through the lens, you must learn to keep both eyes open. This is why many digital cameras now have LCD screens, so you can look with your eyes open. But most photography professors who teach people to take pictures will tell you to keep your eyes open! This is meaningful because it can make you more aware of your surroundings. But for most people, it is easier to turn a blind eye.

The first thing biologists told me was to keep your eyes open when observing through a microscope. Again, it's only because it puts pressure on your facial muscles and eyes. But when you use a microscope, you actually look directly at the light source, so unlike a telescope, you want to see the light with your other eye.

Therefore, for these three purposes, many professionals will advise you to keep your eyes open, but they also know that it is not easy to transfer from one eye to the other, because people are "trained" to use both eyes from birth. Finally, this is not a matter of keeping your eyes open, but a matter of doing a good job. So in general, this is not important, it is mainly about the discussion of opinions. It is easier to concentrate with one eye closed. Keeping both postures open will make it easier for you to relax.
