Dear plaka.endri, thanks for the question. If your spectacle correction power exceeds -6.0 D then you will be classified as a high myope. In that case any heavy exercise such as lifting weights can render you susceptible to retinal detachment
and/or bleeding from the retinal vessels. Also since you have already mentioned that you had bleeding in your eyes, it is advisable not to strain yourself too much as it might lead to adverse effect on your eyes. However you may continue with light exercises to keep yourself fit.
