Which is better for cycling and running?

Both use the same Radar EV Path frame, so fit and venting are identical. The polarized 5138 is the better pick for road and water glare; the 5738's Prizm Sapphire is fine for trail and bright open sky.

Is the white version worth $49 more?

Only if you want the polished white look or Prizm Sapphire tint. The 5738 lacks polarization, so on specs the cheaper 5138 gives you more for less.

Do both protect against UV?

Yes. Both list 100% UV protection and a UV rating of 3, and both are vented and shock-resistant.

Both use Oakley's O Matter frame, so durability is comparable. Lens life depends on care; polarized coatings on the 5138 can scratch, and the white frame on the 5738 shows wear sooner.

Can I wear the polarized 5138 for driving?

Yes, and polarization helps with dash glare. It can darken some car displays and tinted windows at certain angles.

Do they fit the same?

Yes. Both are size 38 with a 128 mm arm and 138 mm bridge, so fit is the same large sport frame.
