Is it bad

Hello I discovered i had myopia and amblyopia in my left eye when i was 7 yo. I used my glasses for women years, after that i stopped for approximately 7 years and last year i got new glasses -1left and -0.75 right, but I couldn’t see anything at far with my left eye This week i went to the doctor and gave me -1.25 right and -1.5 left and i was able to read at far with my left eye. I work everyday on pc and i m a little bit concerned. I am 25 yo rn, should i be worried, are they gonna worsen very much? And why i was able to see with my left eye so clearly? Thanks and sorry for any english mistake
