I bought a set of these recently in Lidl and, as that strange yellow object was in the sky today, thought I would put the dark lenses in. I eventually wrestled the originals out but just can't get the others in. The hook at the nosepiece seems too inflexible.
If anyone has these and has worked out how to change lenses can you please put a confused old git out of his misery?
I've tried Googling, to no avail.
Thanks
