I am 24 and have -6/-8 myopia and the last time I was checked was in 2014 or 2015.
After my friend got partial loss which likely caused by retinal detachment I got paranoid over my sight.
After the new year I tend to stay up late and play games (about 3-6) hours a day (previously it was lesser and sometimes I don't play at all) including reading some comics books or novel that is roughly the same.
After a while I felt like my right eye swollen and sometimes itchy though there's no symptoms of RD such as Flashing (I do get migraine/cluster recently likely because strong smell or overtired which cause me to get photophobia and sound sensitive), sudden floaters, curtains, tunnel vision, visual impairments etc. But because of this I still paranoid over it. I tried to consult with my mother but all she said was get a rest. I do want to get a check up but I have no money for it. Also I kind of want to get my glasses replaced because it felt blurry due the lense already scratched all over the place which hinder the sight.
PS: I do feel bad for straining my body and eyes too much. But I always have anxiety as there's no people I can talk to in real life.
