Some lenses are too thick to fit in metal rims, and some large-correction prescriptions are best suited to frames with small-area lenses. Rimless freshlook frames are the least noticeable type, and they are lightweight toric because the nosepiece and temples are attached directly to the lenses, eliminating the weight of the rims. They tend to not be as sturdy as frames with rims, so they are not a good choice for people who frequently freshlook remove their glasses and put them on again.
