It seems like an irrational fear, but prolonged video game sessions do impact our eyes. Digital eye strain is a common problem associated with excessive gaming. It usually triggers symptoms like headaches and dryness in the eyes.
Low screen contrast, combined with too much glare, is why it happens. It’s necessary to rest the eyes every once in a while. By the way, this doesn’t apply to just gaming.
Any activity that involves staring at a screen for a long time can tire your eyes out. To avoid this, installing proper lighting in the room helps, as well as wearing gaming glasses.
