In the eyes of both the Gray Dwarf Chieftain and the Stone Giant Administrator, there was a faint glow, indicating they possessed dark vision.
Even for ordinary people, transitioning suddenly from darkness to a place of brightness can be overwhelming for the eyes.
Let alone those creatures from the Dark Domain who have lived underground their entire lives; the sunlight on the surface is hard for them to adapt to in a short time. Even if it doesn't result in permanent eye damage causing blindness, it's close to being half-blind, limiting their vision.
Just as most surface dwellers entering the Dark Domain will be severely affected.
The Ghost Eye Blindfold showcased excellent effects in this regard, with its Shadow Power perfectly neutralizing the light that harms their eyes. Although it has drawbacks, such as dimmed vision (leaning towards black and white) and partial limitations, it's much better than enduring it directly.
