Ive got these symptoms right now, I'm a 17 year old female.
Ive just started to read in bed with my lamp at night, so reading these posts has made me think it could be eye strain, but I have just been to the options to get a new glasses prescription (I wear my contacts everyday) and my new glasses prescription is quite a bit higher than my old glasses so I think that might be it as well. Also my new glasses which I wear on mornings and at night when I don't have my contacts in are also slightly stronger than my contact lenses.
Does it sound like my eyes are just trying to get used to all the changes?
