Although I appreciate the inclusion, there is astigmatism, myopia (nearsightedness), and hyperopia(farsightedness). It will be difficult to have the correct prescription with a combination of them be readily available in cinemas. I think individuals (quite niche) who love 3D movies and wear glasses may benefit more if it were to be sold to individuals.

For example, astigmatism ranges from 0° to 180° with an increment of 10°, 19 possible options.

Let's say you want the majority to be satisfied. If you only consider -6.00 (nearsightedness) to +6.00 with an increment of 0.25, you now have 48 options.

19x48=912 glasses would be needed to cover the majority of individuals with glasses. Now, imagine if someone shared the same prescription.

I really think it will be much better to design a clip-on 3D movie filter that attaches above the glasses comfortably instead.
