Global Vision, MAXX, Solar, Bobster, and Eyeride.

Those brands are decent and inexpensive. You can find decent gasketed glasses and goggles with all the necessary features you may want without breaking the bank. I have a pair of Bobster's that have served me well. I might recommend looking into the photochromic - they work well enough and are very convenient.

 

WileyX Air Rage with Facial Cavity Seal.

 

Wireframes are horrible for riding with the raised nosepieces and all. Any plastic framed glasses will do the job.
I have prescription Wiley x with the foam gasket they are great with or without the gasket. I have N-I-K-E and Rayban regular prescription plastic frames with transition lenses and they are fine as well even though they are much smaller lenses. They fit tight around the nose and that is the key.

 

 

I used to buy these and were great http://www.amazon.com/Pairs-Kickback...=global+vision. Also have owned Maxx glasses. Cheap but work great for what you are looking for

 

I have always been a Ray Ban fan but as an ex FL resident I agree the Costa Del Mar are among the best but have also had several pairs of under $20. riding glasses from Amazon that worked well but weren't very durable. I need bifocals now so I need to find riding glasses with bifocal magnification but not RX.
While I was at Daytona bike week this yr. I got tired of trying to find shades, clear and night glasses all with bifocals and came across a vendor selling Icicles.
https://www.icicles.com/
They are made from aircraft alum. with removable cushion and high tech Polarized,Transitions lens with anti glare and bifocal. I can wear them in any light from bright sun to night, comfortably and thy come with a lifetime warranty for lenses and frame- will replace frame if damaged and lenses if they get scratched, at any time.
I went crazy and spent $220. for these but I don't regret it. They are the best glasses, built specifically for riding, that I have found so far.

 

Where do you get liberty glasses? I also have a prescription and am looking for riding glasses.
Tks

 

 

 

I have these, if you don't like them Amazon has the best return policy.
