Following rigorous studies, it was discovered that using the smartphone under a dim light or standing in a dark room not only "steals" your sleep but can also weaken your eye sight, the electron beam affecting the eyes, and causing drying of the conjunctive tissue which it could later turn into cancer and could leave a person blind. But this can only happen if the light source is kept VERY close to the eyes, which does not happen too often when using electronic devices.
However, a 40-year-old man was diagnosed with eye cancer after he complained to the doctor about severe eye pain. He stated that he always used his smartphone for at least 30 minutes in the dark, before going to bed. This usually led to macular degeneration and the appearance of eye cancer.
Unfortunately, in the case of this man, the doctors could not do anything, because replacing the retina is an extremely difficult procedure for the medicine of our times.
