If you have spent any time with high-end AR glasses like XREAL, Rokid, or Ray-Ban Meta, you know the "AR Mark" — those angry red dents on your nose bridge after just 30 minutes of use. Most people think it is just "heavy glasses," but the physics is more malicious than simple weight.
1. The Lever Effect (Gravity vs. Momentum)
Most AR glasses weigh roughly 75g-85g. For reference, a standard pair of Ray-Ban Wayfarers is about 45g. However, because AR glasses concentrate all their optics and heat-sinking metal in the front frame, the center of gravity (CoG) is shifted nearly 2cm forward. This creates a rotating downward force, prying against your skin instead of resting on it.
2. The Calculation: 15g of Constant Friction
Through our internal testing at SGG, we found that this forward CoG produces approximately 15g of localized shear force per nose pad. That constant friction is what causes skin irritation and the "clamped" feeling.
3. The Solution: Crown Suspension (Physics > Foam)
You do not need softer nose pads. You need to remove the nose from the equation entirely. We designed the SGG LIFT using a crown-suspension principle. By shifting 80% of the weight to your head crown, we reduce nose pressure to less than 5g.

"Nice daily camera especially fit for asian face... but the weight distribution is still front-heavy." — r/rokid_official (Anonymized)
"The audio on the Air 4 Pro actually surprised me, but I cannot wear them for a whole movie without them sliding down." — r/RayNeo (Anonymized)
