Does anyone here frequently swap out Flak Jacket lenses? I picked up a set recently and have been wanting to do something in HI Yellow to help with night driving issues I've been having. Was hoping to avoid devoting a pair of glasses, especially as cool as Flak's, for just that, so considered doing a regular lens normally but on occasion using the HI Yellow at night. Is there risk of hurting the frames or lens tabs with frequent swaps, or doing damage from wear associated with switching? Thanks.
