I am a 22 year old female and have been having extreme eye fatigue. Today I was writing an exam, when I switched from staring at the paper infront of me to looking at the clock across the room, I could barely see anything. It took me maybe 2 minutes for my eyes to accomodate. I didn't have any problems focusing back on my paper. Only problems trying to go from close to far. My eye muscles are feeling really tired and I feel like my periphery vision is decreasing. I'm quite worried.
