Our Story
My name is Cord Linville, and I’m an optometrist based in Des Moines, Iowa. The Fatigue Free Specs journey began in optometry school, where I faced my own challenges with eyestrain and headaches, particularly during long hours of studying and computer work. Years later, my brother Cain, a plastic surgeon, reached out to share his own struggles. He was experiencing similar issues in the operating room—eyestrain, headaches, and neck strain—caused by the demands of his precision work.
Recognizing the shared challenges we both faced, I decided to introduce him to the anti-fatigue lenses that had previously helped me. These innovative lenses not only provide clarity for distance viewing but also offer a little extra power for tasks that require close focus, like surgery. The result? Improved reading, reduced strain, and enhanced comfort for Cain during his procedures.
At Fatigue Free Specs, our mission is to ensure that our patients experience the same relief and clarity that we have found. We understand the impact of eyestrain on everyday life, and we’re dedicated to providing personalized solutions that cater to your unique visual needs.

Not your ordinary lens
Our lenses are different from standard single vision lenses. They allow you to see around your room like the operating room(also clinic or computer), but give you an additional power for closer activities like surgery, allowing for a greater depth of focus than single vision lenses. They also are different from regular progressive lenses. Progressive lenses have peripheral distortion in them, where our lenses do not, allowing for a larger field of view. These lenses are not designed for distance viewing like driving.
Personalized for you and your work day
These innovative lenses are perfect for those who engage in continuous visual tasks. At FatigueFree Specs, we’re dedicated to providing personalized solutions to help you overcome vision and focusing challenges whether you’re in the operating room or reviewing charts on a computer.

Client Testimonials
See how our anti-fatigue lenses have helped others!

Getting the anti-fatigue lenses changed my life!!! I didn’t realize my headaches, dry eyes and general eye strain feeling was tied to my vision. As a student I spend 90% of my time looking either at a screen or textbook and I used to need to put heating patches on my eyes at the end of the day to deal with the pain. It’s been over a year having the prism and anti-fatigue on my glasses and all the issues I had have disappeared over night. Can’t put into words how much I appreciate Dr. Cord working with me to find a solution that actually worked for me!

Dr. Cord Linville prescribed me computer/ screen glasses with an anti-fatigue lens last year. I LOVE THEM! I see a neurologist for migraines and take several meds/ injections. These lenses work GREAT with my treatment plan in preventing migraines. I am a full time student with two jobs, I use screens A LOT. I highly recommend utilizing these lenses if you experience headaches and are on the screen a lot. Thank you Cord!
