- Which is better for driving?
- The Eddie Bauer clip-on, if you already own the EB32066 frame. Its tinted lenses cut glare and block UV, and it detaches indoors. The CK23521 alone has clear demo lenses and needs separate clip-ons for sun.
- Can I put prescription lenses in both?
- Yes for the CK23521, which takes single-vision, bifocal and progressive lenses. The Eddie Bauer clip-on is a tinted attachment, not a lens holder; the prescription goes in the EB32066 base frame.
- Is the Calvin Klein worth the price?
- At $16.99 to $29.99 for the frame alone, it is cheap. Budget for lenses, which usually cost more than the frame. The Eddie Bauer clip-on had no listed price, so compare once you have one.
- Which lasts longer?
- The CK23521 is a plain plastic frame with metal temples and no moving parts. The Eddie Bauer clip-on relies on magnets and a clip, and one buyer reported a break after 14 days. Treat the clip-on gently.
- Do the sizes match?
- They are close but not the same. The CK23521 is 53-16-145 with a 43mm lens height. The Eddie Bauer clip-on is built for a 53mm lens, 17mm bridge and 141mm temples. The clip-on only fits the EB32066 frame.
- Which comes with more accessories?
- The Eddie Bauer clip-on includes a premium case and cleaning cloth. The CK23521 listing shows only the frame with demo lenses, so you would buy a case separately.
