Green-reading and yardages in your eyeline: front/center/back distances, hazard carries, and a suggested putt line · 5 pros & 5 cons

The BirdiLens GV1 is a golf head-up display in sunglasses form: yardages to the front, center, and back of the green, hazard carries, and a suggested putt line float in view while you address the ball, drawing on course data BirdiLens claims for more than 40,000 courses. The display is a single-color green Micro-LED shown to both eyes -- 640x480 pixels at up to 2,000 nits, which is how bright the screen can get (1,000+ holds up in daylight). BirdiLens' spec sheet lists 44 grams, Bluetooth 5.3 with 2.4GHz Wi-Fi, magnetic USB-C charging, and 2 hours of display time from the 200mAh battery, so a full round means using the display in bursts. There is no camera. At $899.99 direct from BirdiLens, the store showed sold out with a notify-me form when we checked (October 7, 2026).

Pros & cons

Pros

Green-reading and yardages in your eyeline: front/center/back distances, hazard carries, and a suggested putt line
Course coverage BirdiLens puts at 40,000+ courses worldwide through its app
Bright enough to claim daylight use: up to 2,000 nits on a monochrome green Micro-LED
No camera -- nothing on your face records the course
44 grams with a die-cast magnesium-aluminum front and beta-titanium temples, per BirdiLens

Cons

2 hours of display time per the spec sheet -- a full round means rationing the display
$899.99 is flagship-glasses money for a single-sport device
Sold out at BirdiLens' own store when we checked (October 7, 2026), with no other retail path
BirdiLens' own pages disagree with themselves on field of view (40 vs 30 degrees) and battery (2 vs 3-4 hours) -- we show the formal spec-sheet figures
Young company (founded 2025) selling direct only -- support and parts depend on them staying around
