I have been personally struggling over the past 10 years with the challenge of getting prescription eyewear to use while doing torch work. In the past I have had to buy new prescription didymium glasses every time my eyes changed significantly and I had to get new glasses made.
I have had didymium glasses that had a prescription for close-up work for years, but when I look up and focus on something farther away I get slightly seasick and I have to change back and forth to my regular glasses in order to not get a headache.
I decided I had to try the Fit-Over style of didymiums when they became available and I am thrilled with being able to see no matter where I look. Plus I don’t need to get a new pair of prescription didymium glasses anymore!
I highly recommended this eyewear solution for all lampworkers who wear glasses, especially bifocals or transition lenses.
