AuraLens adapts to your environment, not the other way around:
★ First Gear (48%) — nearly clear. Office, café, indoor use. Looks like regular fashion glasses.
★ Second Gear (35%) — light tint. Overcast days, shade, morning commute.
★ Third Gear (21%) — medium dark. Bright sun, outdoor activity, driving.
★ Fourth Gear (10%) — maximum protection. Beach, desert, direct overhead sun.
