Hey, I am 16 and I have myopia. Currently, my glasses are -4 and my optometrist gave me bifocal lenses to help with my close vision. I just got my lenses changed 2-3 months ago and I'm starting to notice a decline in my vision. I was wondering if I should wear my glasses when reading and writing since I have to be pretty close to the book or the table to see things clearly. I read that my vision should stabilize by the time I turn 18-20. However, is my decline in vision going at too much of a rapid rate?Also, I am considering getting contacts but would bifocal contacts cost a lot or take a while to get used to? thanks
