Custom Eyewear Lab in San Antonio, TX

Our Industry-Leading Lens Lab — Your Perfect Eyewear

Lens manufacturing has changed a lot since our founding in 1938, but one thing that hasn’t changed is our dedication to excellent eyewear. And crafting custom glasses frames and lens combinations, using modern lenses with specialty coatings and designs, lets us better serve our customers. Controlling the production of our own lenses with our San Antonio-based lens lab means we have a fast turnaround time for eyewear that just can’t be matched anywhere around.

Always Putting

Customers First

In our many decades in the eyewear industry, we’ve always sought to stand out from other opticians with exquisitely crafted custom eyewear and service that always prioritizes our customers. Our lens lab is a continuation of that goal: to provide the industry’s best lenses, personalized to your needs, as quickly as possible.

Why We Started and Still Craft

Top-Quality Custom Eyewear

Simply put: establishing our custom lens lab came down to control and service. We found that it was too easy for details or even lenses to disappear in a larger manufacturing process, and plenty of reasonable requests could get caught up in red tape. So, we took control of our own destiny. In our custom lens lab, we know exactly who is working on which lenses, what accommodations are possible, and we can take full ownership of our output. Even when there’s an occasional delay, we’re still faster than the rest!

Our Roots in Custom Eyewear

DM Optical owners Drake and Cliff McLean have generations of optical experience and knowledge that’s been handed down to them since their grandfather, “Mac”, founded their shop over 80 years ago. Throughout our extended history, we’ve been interested in the science and design of custom lens making, and today, taking on that work ourselves is a pivotal part of how we provide our customers with ever-more incredible eyewear.

The staff is excellent. Kayla was super helpful. I needed assistance with the temple ends on a vintage pair of Rayban glasses. She replaced them perfectly. She also adjusted them to fit my face better than they were prior. I will return to Dietz-McLean for all of my optical requirements. Thanks Kayla for the top notch service.

I have been a client for many years and have always had great service. I just picked up 5 pair of eye glasses and they fit them well and got the prescription perfectly.
