In the same situation as you. I need glasses for distance (near sighted) and only wear a half helmet; cannot stand shields or full faced.
I have my regular glasses, and had a set of prescription sunglasses made up years ago which I know are not the best but at the time, they cost $380 CND which 80% was covered under my work health plan; if I was go go for the goggles they would have cost just over $600, and would have not been covered.
The down side to me is I suffer from photophobia (eyes are sensitive to light) so I need tinted glasses when riding on sunny days.
I'm not sure if the pricing has come down over the year but would be curios to check it out.
Another option which was suggested at one time, was to get a large set of goggle that the glasses would sit behind; this is not a bad option because you could use both sunglasses or regular pair under them, but they looked and felt really awkward on.
