Are the RB4179 lenses polarized?

Yes. They are P3 polarized polycarbonate lenses with a dark green gradient tint and 100% UV protection.

Will the 62-13 size fit my face?

The 62 mm lens width and 13 mm bridge with a high bridge fit suit medium-to-wide faces. If you normally wear narrow frames, this one will feel large.

Is the Liteforce frame metal?

No. It is an injected semi-crystalline thermoplastic bio-material, which is why it flexes. It is not the metal frame some shoppers expect from the Liteforce line.

Can I swap the lenses?

No. The RB4179 does not take interchangeable lenses, so the green gradient P3 lens is the only option.

What comes in the box?

Ray-Ban typically ships these with a case and cleaning cloth. Confirm the included accessories with the store before ordering.

Is the RB4179 worth it?

It is worth it if you want a light, flexible frame with polarized lenses and a wide fit. If you want metal or interchangeable lenses, look elsewhere in the Ray-Ban line.

About the Ray-Ban RB4179 Liteforce Sunglasses

The RB4179 Liteforce is a full-rim men's sunglass with a flexible injected bio-material frame and P3 polarized green lenses. The lenses are dark with a gradient and carry a hydro-oleophobic coating that sheds water and fingerprints. The 62-13 size with a high bridge fits wider faces. It sits at the upper end of what this model has sold for recently, so it is not a bargain moment.

Best forMen with wider faces or a high bridgeEveryday driving and bright-light useBuyers who want polarized lenses in a light, flexible frameShoppers who prefer a classic Ray-Ban look over sport frames

Pros

P3 polarized lenses cut glare and give 100% UV protection
Lightweight injected bio-material frame flexes instead of cracking
Hydro-oleophobic coating repels water, sweat and smudges
Full-rim shape holds lenses securely
62 mm lens width suits broad faces

What reviewers say

4.7 / 5387 ratings

What people mention

WeightPraisedOwners say the Liteforce frame is light enough to forget you are wearing it.
PolarizationPraisedReviewers say the polarized lenses cut glare on roads and water.
Frame flexPraisedThe injected frame bends and springs back, which owners credit for surviving drops and bends.
TintMixedThe gradient darkens the top of the lens, and some owners find the lower part too light in bright sun.
Lens careMixedThe hydro-oleophobic coating helps, but owners say the lenses still smudge and need frequent wiping.
