What are TR90 Glasses?
Glasses need to be comfortable. But it can be hard to find comfy frames that withstand daily wear and tear. That’s where TR90 can help. TR90 is a flexible, damage-resistant thermoplastic that’s very durable. Thanks to its pliability, TR90 absorbs impact without breaking. And because it's lightweight, TR90 frames fade into the background so you stay comfortable all day.

Pupillary distance is the measurement between the black centers of your eyes (the pupils). We use this measurement to precisely design prescription lenses. To measure your PD, place a millimeter ruler on the bridge of your nose, just below your pupils. Use a mirror or have someone align the first millimeter line with the center of one pupil, then read the measurement. You can also use this helpful tool to measure your PD with a phone camera or webcam.
The easiest way to provide your Rx info is to upload a picture of your prescription, but you can also enter your info manually. Glasses prescriptions are divided by the right and left eye. Eye doctors use the labels O.D. (right eye) and O.S. (left eye). Look for those labels on your prescription followed by a series of numbers. Enter the numbers in the corresponding boxes on the prescription screen, then click continue.
We quickly ship most orders in 2-7 business days. If your order includes a complex prescription, it could take up to 4 more days to process. 39DollarGlasses is dedicated to quality, so every order undergoes strict quality inspections before shipment.
