Note: the actual pupil distance corresponding to the limit of moving P2 product lens inside is 62 mm, in order to keep the users from feeling that the lower IPD limit of adjustment is too large so that the display data is reduced by 2 mm. For example, the display distance of pupil is 62 mm, buy the actual pupil distance is 64 mm. 

Principle of IPD regulation: three points (eyeball center, lens center and LCD display distortion center) need to be in a straight line.

Note: a wide axis and a lens always remain perpendicular. Besides, the LCD display area and distortion center follow the adjustment when the lens is adjusted.

If the default pupil distance is 62 mm, the practical wearer's pupil distance will be 65 mm so that the lens needs to be adjusted to the outside direction.
