The only time you'll catch me shooting without eye protection is if someone is trying to kill me. That is today. As a young man I didn't wear them. A pierced primer changed my tune. Thank God I didn't learn that lesson the hard way.
I use Randolph Ranger XL frames. They have an adjustable bridge so that they fit properly whether my cheek is on a stock, or I'm looking straight ahead shooting handguns. The lenses are interchangeable.
If you need prescription lens inserts I suggest you get them ground by Morgan Optical or Allan Lehman Optical. They are shooters and understand what a shooter needs.
I have a variety of lens colours, including custom dyed colours, both polarized and non to match shooting conditions and targets (note, that I first got these for competitive trap shooting and taking such things as brightness, clouds, glare, background colour, target colour, angle of sun, etc., can actually give you an edge and allow you to maximize contrast).
I also have a pair of "shootoff lenses" (trap shootoffs can happen at the end of the day, even at night under lights). These clear lenses are coated on both sides with anti-reflective coating that maximizes light transmission. I don't believe you give up much light or clarity using these. You would not feel like you're taking away much of anything from the quality of your scope's glass.
The lenses are thick (much thicker than your typical wrap-around sport shades) and should offer significant protection. And the optical quality of the lenses available is outstanding. They should appear optically perfect (I said "appear"!). They do not suffer the distortion that happens with wrap-around sport shades.
I'm pretty sure your typical shooter would consider the cost of getting set up with frames and lenses like the Rangers pretty steep. Especially for non-prescription or "plano" lenses. But taking into account the cost of your rifle, scope, and your irreplaceable eyes, I think they're well worth it. I own two frames and a host of lenses and I've never regretted the outlay for a minute. Amortize them over the rest of your life and they are dirt cheap.
EDIT: I also always wear side shields with them; keeps out the wind and dust and my neighbour's empties.
