Exchange the Lenses
You can easily change the lenses of your Pupil Invisible glasses. A pair of shaded lenses is included with every device.
You can get custom lenses with specific prescription values at any optician. Alternatively, you can purchase a lens kit from the Pupil Invisible accessories page.
Hold the glasses with the arms of the frame facing towards you. Push out from the inside of the frame on the lens surface with your thumb placed close to the nose pad.
You will hear a pop sound when the lens is removed or inserted. Don't worry - the frame and lenses are durable!
Hold the glasses with the arms of the frame facing away from you.
- Slot the lens in the groove on the side furthest from the nose pad.
- Press on the lens with your thumb or fingers on the top corner closest to the nose pad.
