Research Proven: Precision-tinted lenses reduce migraine attacks by up to 74 percent¹, ease light sensitivity, relieve eye strain and reduce headaches.

Protection: TheraSpecs® FL-41 tinted lenses block 80% of blue light, which is known to trigger migraines, photophobia, and other light-sensitive conditions.

Better Relief Than Sunglasses: Wearing sunglasses indoors worsens light sensitivity over time². By blocking only problematic light, TheraSpecs indoor lenses are lighter and offer more long-term relief from fluorescents and screens.

Sunlight and Glare Protection: TheraSpecs outdoor lenses provide better protection against bright sunlight than regular sunglasses. They are dark, polarized and 100% UVA/UVB blocking.

Comfort: Ultra lightweight metal frames with adjustable nose pads minimize pressure on your face and head for all day comfort and relief.

Guarantee: 9 out of 10 customers find relief with TheraSpecs. If you don’t like our glasses or experience the benefits, return them within 60 days for a refund.

More Than Just Glasses: Every pair of TheraSpecs comes with a complimentary protective case and a microfiber cleaning cloth.

Lens Type: (learn more)

Lens Type

TheraSpecs are available with either indoor or outdoor lenses.

Indoor lenses are tinted lighter than sunglasses so they do not risk the dark adapation problems that wearing sunglasses inside can cause and people can still see your eyes. They are designed to protect you from artifical lights such as fluorescents and computer screens.

Outdoor lenses are dark, like sunglasses, and also are polarized, which greatly reduces the bright glare that comes from sunlight reflecting off flat surfaces like roads, cars, and water. They are designed to protect you from bright sunlight.

What should I choose?

You should choose the lens type for use where you have the most issues, or order one of each (an indoor + outdoor set for non-prescription lenses or as two separate prescription/reader orders).

Required

Indoor

Designed to protect from fluorescents and device screens

Outdoor

Darker, polarized to block glare and bright sunlight

Reader Type: Required None

Full lens

The whole lens includes magnification

Bifocal lens

The reader is in a lined bifocal area toward the bottom of the lens

Reader Strength: Required

Prescription Type: (learn more)

Prescription Type

This option specifies what type of prescription you have.

Choose single vision if your prescription is not a bifocal prescription. If the "add" portion of your prescription is blank then it is single-vision.

Choose lined bifocal if you have a bifocal prescription and would like the magnifcation portion to be in its own "window" at the bottom of each lens.

Choose no-line/progressive bifocal if you have a bifocal prescription and would like the magnification portion to blend with the rest of the lens so there is no distinct "window" at the bottom of the lens.

Required None

Single vision

The whole lens has the same correction

Lined bifocal

The lens has a separate window for the reader portion

Progressive/multifocal

The reader portion blends seamlessly into the rest of the lens

Pupillary Distance (PD): (learn more)

Pupillary Distance (PD)

What is pupillary distance or PD?

PD is the distance in millimeters between your pupils when looking forward. This can either be listed as one number like "64" or two numbers like "30.5/31.5". It is necessary for all prescription orders.

Where do I get this measurement

It may be written on your prescription already, but it's not a standard part of the prescription itself so it is often not written down by default. If it's not on your prescription it's likely on file at your eye doctor's office - just call their office and ask for your PD. If they do not have it on file, any optometrist or optical shop can take the measurement for you in just a few seconds.

What should I enter?

Enter the one or two numbers labeled PD on your prescription or the number or numbers your doctor's office provided you.

Required

Segment Height: (learn more)

Segment Height

What is segment height?

Segment height is the distance from the bottom of your lens to the top of the bifocal or progressive section of your lens. It determines how much of the lens is the "add" portion vs. the distance portion. NOTE: Segment height is unique to each given frame and prescription and therefore must be measured in the frames you will be using.

What should I enter?

If you are buying TheraSpecs frames then leave this option blank. We will mail you a pair of the frames you selected after you complete your order. You can take these to your eye doctor to have your segment height measured. Then you'll send us that measurement and mail your frames back for our optical lab to complete your order.

If you are sending us your own frame that does not have lenses with your prescription installed then you will need to take those frames to your eye doctor to have segment height measured.

If you are sending us frames that already have lenses with your bifocal, trifocal, or progressive prescription then you may leave this field blank. Our optical lab will measure the segment height of your existing lenses to use for your new TheraSpecs lenses.

Lens Material: (learn more)

Lens Material

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.

If you need safety glasses:

Safety lenses: 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.

Required None

CR-39

Most common choice. High optical clarity, best for prescription strengths up to ±2.00

Poly

Shatter-resistant, thinner than CR-39 and Trivex, but lower optical clarity and more prone to scratches than other materials. Good for prescription strengths up to ±6.00

Trivex

Shatter-resistant, lightest, high optical clarity. Good for prescription strengths up to ±6.00

Hi-index

Thinnest lens material we offer. Recommended for strong prescriptions up to ±10.00

Lens Coating: (learn more)

Lens Coatings

What should I choose?

Scratch-resistant coating is included and will reduce the chances of scratching, especially if you live or work in an environment that has extra grit (for example, near a beach or anywhere products are made or packaged).

If you are often annoyed by reflections from behind you, or by smudges building up on your glasses, then the anti-reflective/anti-smudge coating may be a good choice for you.

Required None

Scratch-resistant only

All TheraSpecs lenses include this protective coating to reduce the chances of scratching

Scratch-resistant + anti-reflective/smudge

Adds coating to reduce visible reflections and make cleaning the lenses easier. Scratch-resistant coating still included

Hudson TheraSpecs is a rounded frame that blends a sophisticated, versatile design with the protection of our FL-41 lenses; this makes Hudson perfect for everyday use at the office, at home, or during a night out on the town. They are crafted from lightweight and highly adjustable metal with soft, flexible silicone nose pads to ensure a snug yet comfortable fit.

Hudson TheraSpecs is available in the finish of your choice: black or silver.

Indoor TheraSpecs are great for wearing near artificial light and while using computer or device screens. Some people also like wearing them outdoors on overcast days. Outdoor TheraSpecs provide more relief than typical sunglasses for bright sunlight. Like all TheraSpecs, they:

Reduce headache and migraine frequency and intensity
Relieve painful light sensitivity and glare
Protect you from fluorescent lighting

Hudson TheraSpecs come with a case and a microfiber cleaning cloth.
