Some players in the game had developed high levels of nearsightedness due to certain reasons. These players may encounter some challenges in the game because the vision requirements in the game are very high. Some players with high short-sightedness might encounter other players in the game who could not judge the position and appearance of other players due to vision problems. They might miss some opportunities, especially when searching for supplies and attacking the enemy. Due to the need to shoot enemies from a distance in the game, players with high nearsightedness may need to move and adjust their shooting positions more frequently than other players to ensure accuracy. This might bring them additional fatigue and challenges. Although players with high nearsightedness may encounter some challenges, they can still improve their vision problems by wearing appropriate glasses and performing appropriate vision training. In the game, they needed to stay alert and adapt to the visual requirements in order to gain an advantage in the game.
