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.
If you need any help chat with us online, email us at firstname.lastname@example.org, or give us a call at 602.456.6896. We are available Monday - Friday, 9 am to 5 pm Phoenix, Arizona, time.
A Few Definitions
Pupillary Distance: The distance in millimeters between your pupils when looking forward. This can be a one- or two-number measurement.
Segment Height: The measurement from the bottom of your a frame’s lens to the top of the add power “window” in your bifocal/progressive prescription. This measurement is unique to the frame style chosen.
Choosing a Lens Material
CR-39 provides the best optical clarity. It is best for prescriptions with strengths up to ±2.00. For prescriptions stronger than that, it will be much thicker and heavier than other materials. CR-39 can not be used for rimless or semi-rimless frame styles.
Polycarbonate is good for shatter-resistant (see note below about safety glasses) lenses in strengths up to ±6.00. Polycarbonate is thinner than CR-39 and Trivex, but more prone to scratches. Because polycarbonate has lower optical clarity than other materials, if you have trouble with halos or blurry peripheral vision, please choose a different lens material.
Trivex is the lightest-weight lens material available (but not the thinnest), and suitable for prescriptions with strengths up to ±6.00. It is shatter-resistant like polycarbonate, making it suitable for safety glasses, but has better optical clarity and is more scratch-resistant. Choose Trivex if you have similar needs as polycarbonate but want something even lighter weight.
High-Index (1.67) is the thinnest lens material we have available, recommended for strong prescriptions up to ±10.00. This lens material cannot be ordered with anti-reflective coating at this time, and is only available for indoor lenses.
If you need safety glasses:
While all polycarbonate and Trivex lenses are shatter-resistant, if you need ANSI-certified, safety thickness lenses please contact us. If you require your glasses to be certified safety glasses, you must also send us frames that are ANSI-certified for us to put lenses into. Certification requires that both the frames and the lenses be certified.
