I had the same question, so I asked Endura. * With your thumb and forefinger, grasp the frame firmly at the centre of the glasses (above the nose piece). * With the other hand, grasp one of the lenses close to the nose piece between thumb and forefinger. * Pull the lenses downwards firmly away from the frame. They should release with a bit of effort. To insert other lenses, reverse the process... * Align the new lenses to the slot in the frame. * Hold the lens between thumb and forefinger close to the nose piece. * Whilst holding the frame firmly at the centre with the other hand, push the lenses firmly upwards into the frame. It should click into place.
To change the color of the emitted light. Also to reduce and tint incoming light - such as sunglasses.
To change the lenses, hold the nosepiece and pull the lower-inner corner of the lens (closest to the nostril).
you punch it out with your thumb
after messing with mine i can tell you they press from the inside out, the bottom corner nearest nose first
This is the depth of a pair of sunglasses. 1d is straight, 9d is very curved. So 9d lens bases will also cover the sides of eyes...

I did the following... step by step, if you have any questions, please ask. - I placed the sunglasses perpendicular to me. One if the lenses will be close to you, while the other should be farther away. -I grabbed the farthest lens from your body with both hands. Placing your left had on the left side and your right and on the right side. One had is on the bottom of the lens, while the other is on the top of the lens. It does not matter which hand is on the bottom or top. -I grabbed the top and bottom of the frame, pulling away from the lens. At the same time I pushed with my fingers (that should be on the inside of the lenses) and pressed the lens out (on the lens closest to the nose pieces). You will hear a very faint "pop" when the lens clears the frame. -Then slide the lens out by grabbing the part that is out of the frame that is close to the nose piece -To put the new ones in, position the sunglasses the same way and put the replacement lens in the sunglasses, starting with the edge near the ear pieces. -Pull the top and bottom of the frame out and push the replacement lens into place. If you have any questions, please ask. If I can clearify anywhere, let me know. Good luck.
you were wearing photochromatic sunglasses then you would not have had to take off and then put on your sunglasses. The lenses would have reacted to the change in light conditions and would keep your eyes well protected throughout your journey. A photochromatic lens will only alter in the area subjected to change in light, therefore if only one part of peripheral vision is subjected to an increase in light intensity then only that part will change. Every area of the lens is fully independent from all other areas.
