Adjusting eyeglasses frame

Who at lakeside can adjust stretched out wireless eyeglasses frame?

Actually they are rimless glasses.

There is a little 'Optica' shop in Chapala on Degollado (NE corner of Degollado & 5 de Mayo) that I have used for new rimless glasses (several pair over time) and repairs. Sorry don't have the phone number.  Very reasonable. They should be able to restring the tension catgut on your rimless easily.  I like them as I can bring in my own frames & they will put lens in for $75-$100. Nice people & turnaround is good, they send stuff to Guad.  I've found some high quality frames @ Riberas thrifts (Oliver Peoples!) Their lens quality is good too. Gotta have my back-ups ~
