'''Focals by North''' (also known as '''North Focals''') was a smart glasses product developed by [[North Inc.]] (originally Thalmic Labs), announced in October 2018 and released in January 2019. Representing one of the most ambitious attempts to create consumer smart glasses that looked like regular eyewear, Focals used a holographic projector built into the right temple that projected images onto a tiny photopolymer film square embedded in the right lens, creating a retinal display visible only to the wearer. The glasses featured Alexa integration, turn-by-turn navigation, notifications, calendar events, weather, and messaging—all controlled via the included Loop ring controller worn on the finger. Weighing 65-80 grams depending on style and prescription lenses, Focals claimed 18 hours of battery life and IP55 water/dust resistance. The glasses required custom fitting at North's showrooms (initially Brooklyn and Toronto), with pricing starting at $1,000 before being reduced to $599 ($799 with prescription lenses). Despite positive reviews for design and concept, Focals faced challenges with limited availability, required in-person fitting, and small display. North was acquired by Google in June 2020 for approximately $180 million, after which Focals 1.0 was discontinued and the planned Focals 2.0 was cancelled, with the team reportedly working on future Google AR glasses projects.
