Description of Alpina Twist Five Optical Adapter - clear / clear demo
With the TWIST FIVE Optical Adapter, the TWIST FIVE performance glasses can also be used as optical glasses with vision enhancement.
The lenses of the adapter must be ground in by an optician according to your own visual impairment. This is possible in a dioptre range from +4.0 to -4.0.
The adapter is clipped onto the nostril of the TWIST FIVE from the inside and can be removed just as easily if the sports glasses are used in conjunction with contact lenses.
