Frequently Asked Questions

Do you offer free shipping?

Do you offer free returns and exchanges?
Yes. With our 30-day free return and exchange policy, you can try on your sunglasses at home and make sure they’re the right fit for you.

Can I put prescription lenses in my sunglasses?
Yes. Any optician will be able to help you install prescription lenses into our frames.

What if my sunglasses need adjustment?
Most optical shops will make minor adjustments for free or a small fee. We’ll reimburse you up to $50 for a single adjustment within 30 days of purchase. Just email the bill to, and we’ll take care of it!

Where can I find my frame’s measurements?
All our frames have the numbers - 53, 20 and 145 - printed on the inner side of the left temple arm. They refer to the lens width (53 mm), nose bridge width (20 mm) and temple arm length (145 mm).

Every one of our frames has identical measurements, so if one of our frames fits you, all of them will fit you!

What’s a nose bridge? How do I know whether I should wear Standard Fit or Raised Fit frames?
A nose bridge refers to the slope of your nose between your eyes. A low nose bridge is where the bridge of your nose sits level with or below the pupils. Raised Fit frames minimize any pinching and prevent frames from sliding down your nose or resting on your cheeks.

Standard Fit frames will be more comfortable for people with medium to high nose bridges.

Are my sunglasses polarized?
Yes. All our sunglasses come with polarized CR-39 lenses that offer 100% UVA/UVB protection.

How good are your lenses?
Our lenses are made of CR-39, a lightweight plastic polymer that offers excellent optical clarity.

In addition, all our lenses comply with sunglasses safety standards established by the US (ANSI Z80.3:2015); Europe (EN ISO 12312-1:2013(A1:2015)) and Australia/New Zealand (AS/NZS 1067:2003(A1:2009)).

Why does my mobile phone screen look like a psychedelic rainbow of colours when I’m wearing my sunglasses?
Good question!

Polarized sunglasses work by filtering horizontally polarized light, which is common in reflections of the sun off the ocean or snow. Phone screens also have a polarizing filter to cut glare and reflections to improve visibility in bright sunlight. When your phone and sunglass filters are aligned in opposite directions, all the light from your screen is cut out so you can’t see anything. Fortunately, there is a simple solution, rotate your tablet or phone 90 degrees.

Why do I see rainbows in car windows?
The short answer is that back and side car windows polarize light, and when you wear Rocket sunglasses with polarized lenses, the double polarization from your lenses and the car window causes the rainbow effect.

The slightly longer answer is that car windows are tempered for your safety - so they shatter on impact instead of breaking into sharp, dangerous shards. During the window tempering process, the heating and cooling of hot glass causes surface stresses, which makes the glass birefringent - meaning that the windows polarize light rays in different directions. When light reflected from birefringent car windows reaches your polarized sunglasses lenses, the rainbow effect occurs.
