I only have transition lens on my prescription safety glasses because construction sites are hazardous to glasses and eyes at all times. I don't always have clean hands for switching. And switching itself leaves your eyes vulnerable to shit while switching. It's also the only time I don't want polarized lens because they often make screens difficult to read.

For everyday, I carry a polarized set and a regular set and get swapped between the same case. They are basically the same frames too so they both fit because my head is to large for most frames that aren't sunglasses frames anyway. If I'm planning on being mostly outside, I may only bring the polarized lens because they don't actually block that much light inside even though they block about %50 of the light outside. Tinted lens that aren't polarized usually just cause additional eye strain for me anyway. Also only polycarbonate lens for outside also because even if they have no tinting they are blocking UV light.

Clip on lens are prone to trouble. They will either scratch your prescription lens or just get gunked up themselves since you're doubling the surface area that needs to be kept clean.

In general I spend WAY more thought and money on things for or touching my eyes, feet, hands, and private sweaty bits. Try out things and see what works for you. For example, I was surprised how great wool socks are for hot sweaty climates.
