• TR glasses:

         Advantages: light weight, not easy to deform, light weight.

         Disadvantages: poor texture, strong plastic feeling, easy to fade over time

• Acetate glasses: The weight of the acetate is slightly heavier, high hardness and not easy to bend, good texture, almost no fading, generally mid-to-high-end frames will use acetata
• Final suggestion: If you want to pursue cost-effectiveness, TR material is recommended.
• If you want durability and better texture, acetate material is recommended
