Does OD change from company to company for the wavelength? I am looking for laser glasses for a Iridex argon laser, but when I find the right wavelength the OD is different from what is on my existing glasses.
No, the OD does not change from company to company - but it will change by lens type. What are the wavelengths and ODs listed on your current pair? What are the wavelengths and ODs for the laser(s) that is(are) in use?
