Will 1.67 high index lenses be suitable for my prescription and frames?

My prescription is as follows:
-8.00
-8.50

The frames I would like to get are plastic, full-rimed frames. These measurements are all in mm.
Lens Width: 51
Frame width: 136
Temple length: 145
Lens Height: 29
Frame Weight: 20

I would like to get the 1.67 lenses because it it much cheaper compared to the 1.74 lenses and I only plan to use these glasses as backup when I don't want to wear my normal contact lenses. Will this configuration be too thick or is it good enough for light use?
Added (1). I forgot to mention my PD is about 64.
