TheraSpecs in Your Prescription

Alert: The COVID-19 pandemic has caused some disruptions in our optical lab’s normal operations. As a result, some custom orders may take longer than 3 weeks to be completed. We appreciate your patience.
Let us make your single vision, lined or unlined progressive bifocal prescription in our frames or yours.
Rather than tint existing prescription eyewear, we make brand new lenses for you!
Provide your PD, segment height if necessary, and upload your prescription.
Note: We are unable to refund custom orders, they may take approximately 3 weeks to be completed (plus shipping), and there may be additional fees for a strong prescription.

Get a pair of TheraSpecs perfectly suited to your needs

Let us create prescription TheraSpecs lenses in most of our frames or any frames you provide. We can create single vision, lined bifocal, unlined progressive bifocals/trifocals in either our indoor-tinted lenses or our outdoor-tinted, polarized lenses. If you need ANSI-certified, safety thickness lenses add “safety thickness, safety monogram” in the notes section.

Important Next Steps

1) If you are using our frame for a bifocal or progressive, we'll get it sent out to you right away so that you may acquire your segment height locally.

2) If we are creating custom TheraSpecs lenses in your frames, please send them to:

Attn: Custom - [Your Name Here]
24 W. Camelback Road, #A586
Phoenix, AZ 85013

3) Once we receive your frames your custom TheraSpecs will be ready to ship back to you in approximately 3 weeks. We are unable to refund custom orders. If you are unfamiliar with the TheraSpecs lenses we recommend you try a non-prescription pair first. We want to make sure you are happy with the relief TheraSpecs lenses can bring you before you commit to purchasing a custom order.

4) Please indicate any special instructions (i.e. returns or exchanges) about your order in the Notes & Instructions section and we'll take care of you.
