Guilda Pytlíci

I've been playing guitar for a year now, but am still having problems learning the fretboard, or being able to play without looking at it. I've done lots of different guitar speed exercises. One person suggested I play in the dark or with my eyes closed to get used to the sound each note on each string makes. Does anyone have any other suggestions?

I didn't find the right solution from the internet.
