Acetate frames typically have a smooth, warm feel with a slightly heavier weight compared to plastic or PC frames. They often have a more luxurious appearance due to the material's natural texture and depth. And PC frames, on the other hand, may feel lighter and have a smoother, more plastic-like texture. 

Another way to distinguish between the two is through visual inspection. Board material frames often have a more classic and traditional appearance, with visible seams at the joints, while TR90 frames typically have a more modern and seamless look due to their molding capabilities. Moreover, the durability of the materials differs, with TR90 being known for its impact resistance and ability to return to its original shape after bending, while board material frames are more susceptible to breakage. By considering these factors, individuals can effectively discern between board material and TR90 eyeglass frames when making their purchase decisions.
