My typical buyer already has prescription lenses and is in need of replacement frames. xx-xx-xxx The first number is the lens size, if this is different they won't fit. The second number is the bridge, if this is different the pupil center distance will be wrong. The third number is the temple, basically the arm length, isn't as important but should try to match. Lenses are easy to replace, just search YouTube for tips.
If you're looking to buy lenses after buying these frames you may find it very difficult. Unless you're confident, please visit a store where you can try them on.
The used eyeglasses and sunglasses frames I offer for sale are chosen by their light use to prevent any customer dissatisfaction. They have been ultrasonically cleaned followed by a thorough inspection confirming tight hinges. They will include the old prescription lenses to keep the frames square and proper. I will gladly accept returns if the frames are found to not perform well. The sale is for the frames only, the lenses are free.
