Where can I find my frame’s measurements?

You can find your frame's measurements—a set of three numbers—on the inner left temple arm.

From left to right, they refer to the lens width, nose bridge width and temple arm length.

Here are the measurements for our three frame sizes:

  • 53-20-145: Original (143 mm wide)
  • 49-20-145: Tailored (136 mm wide)
  • 47-20-140: Small (132 mm wide)


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. A low nose bridge is one that sits almost level with your cheeks.

Designed for lower nose bridges, Raised Fit frames, as the name suggests, "raise" the frame away from your cheeks and prevent slipping.

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

To learn more, visit our Fit and Size Guide.


If my sunglasses are tight or too loose, can I adjust them?

Yes, all our frames come with adjustable temple arms, so you can adjust them yourself. Just follow the directions in our adjustment guide and let us know if you have any questions!

Alternatively, you can also bring your Rockets to any optician for adjustment. They will know exactly what to do. 


Are my sunglasses polarised?

Yes. All our sunglasses come with polarised CR-39 lenses that offer 100% UVA/UVB protection and glare reduction.


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 are FDA-certified and 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!

Polarised sunglasses work by filtering horizontally polarised light, which is common in reflections of the sun off the ocean or snow.

Modern phone screens also have a polarising filter to cut glare and reflections to improve visibility during usage in bright sunlight. When your phone and sunglass filters are aligned in the same direction, 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 sometimes see rainbows in car windows?

Sometimes, when you’re wearing Rocket sunglasses, which all come with polarised lenses to reduce glare, you may see “rainbows” appearing on the side or rear windows of other vehicles.

Don’t worry - there’s nothing wrong with your lenses or your eyes. The rainbows you see are actually strain patterns in the tempered glass windows.

When car side and rear windows are produced, they go through a process called tempering to prevent them from shattering into sharp pieces. During this process, the glass goes through uneven expansion and contraction because the surface of the glass heats and cools at a faster rate than the centre of the glass. This type of stress on clear materials, such as glass, produces birefringence, which refracts (redirects) light at many different angles.

When you’re wearing non-polarised lenses, you don’t see a rainbow because your eyes absorb light waves of all angles. However, sunglasses with polarised lenses filter all light waves except vertical ones, allowing you to see the strain patterns in car side and rear windows.
