To decide buying a trial lens case, there are some questions should be made clear.
- What kind of lens to be choose, Metal or Plastic?
Some optometrist like metal rim it looks traditional, while some optometrist and doctors like plastic because its light weight and portable.
Metal Rim 
Plastic Rim
2. How many pieces wanted for the case?
Personally as a optometrist I always using a 266pcs case as per which we have now in market, or at least 232pcs, because it provides enough lenses for option, otherwise if we meet some high prescription we have to take more time to confirm by add more lenses.
