Why is the lighting not working properly?

Like the title states, my lighting is somehow not working properly. Even though the debug screen shows that the light level is currently 0, I am somehow still able to see properly.enter image description here


Solution 1:

This is because the trapdoors above you block out light, but are considered transparent blocks. Thus, you can still see around you, as it's transparent, but it is light level 0 because it blocks the light source above it, meaning that your hand appears black.
