The departure from darkness to light is not as disturbing. Because the retina can be adjusted to light. Even in the dark for a long time, it will not be permanent. Unlike people who watch the sun directly. This will cause retinal damage.

"In the retina, we have two types of light-emitting cells: and conical cells for color vision.When we were in the dark the bulb will work harder. As the color cells are less active, there is no color in the dark, so when the light comes in. Excessive exposure to light will make the light more visible. But the retina The photoperiod will return to normal, the colored cells begin to work, everything will return to normal

Or a pair of sunglasses in general because it's used to cut the light for only 5-10 minutes for the retina to adapt to the new environment. Unlike sunglasses in the sun.

But just to gradually increase the exposure, but taking care of your general condition. You can also check your eye for more comfort.
