1) I don't think its consensus that aerosols are a MAJOR source of spread.
2) Masks are much less effective for aerosols than for droplet transmission. I think the consensus is they at least somewhat reduce aerosol transmission. Only n95 w/o exhale vents that are properly worn are believed to be good at reducing aerosol transmission.
The fact that your glasses fog up shows that surgical masks certainly are very leaky.
