I usually wear multifocal contact lenses, but it's time I got some new glasses. I'm not sure I'll wear glasses enough to justify the price of variofocals so I'm thinking of just getting single vision glasses for distance. That means I wouldn't be able to read in them, right? My prescription is -6. So, would cheap reading glasses suffice, or would they not work because my vision isn't corrected enough? I haven't bought glasses for about 9 years and I'm old enough now to have reached the stage where I'd be stretching my arm out to read stuff.
