In this review, I compare the online glasses retailers Zenni Optical, Trioo, and Warby Parker.
Trioo coupon codes:
Enter STAR TREK at checkout for 15% off.
Buy 2 get 1 free: email [email protected] with the subject "Trio of Trioo" and you will be contacted within 24 hours for manual processing of your order.

Disclaimer: Trioo sent me three pairs of glasses to review, and though the glasses were free, the opinions are my own; I would and will never compromise my integrity for the sake of free product.
