7.1.6 Changing the lenses on the Head Unit
Glasses 2 comes with two different protective lenses, one clear and one tinted. The tinted lens is intended to be used in bright

to the Head Unit.
1. Locate the small hook that keeps the lens in place, located between the scene camera and the nose pad at the front of
the Tobii Glasses Head Unit.
2. To remove the existing lens: Gently push the hook downwards while gently turning the lens past the retaining clip.
3. To mount a lens: Fit the position guides into the indentations, and then gently press the lens past the retaining clip so
that it locks in place.
