Here is Private Life’s Guide to choosing the perfect sunnies…

Protect your eyes.

Excessive exposure to UV radiation can cause a variety of problems for your eyes such as cataracts, burns, and cancer. If you want your sunglasses to protect you from these risks, look for pairs that block at least 99% of UVB rays and at least 95% of UVA rays. If they don’t provide any information on UV protection, don’t buy them.

Choose the colour wisely.

The colour of the lenses doesn’t just affect your fashion statement; it affects how well you detect contrast and differentiate colours. Some colours enhance contrast, which can be useful; however, this is often at the expense of colour distinction, which can cause problems (when you’re driving, for example, and need to be able to clearly differentiate the colours at traffic lights).

  • Gray lenses reduce light intensity without affecting contrast or distorting colours.
  • Brown lenses partially enhance contrast by blocking some blue light, which is good for snow sports.
  • Amber/yellow lenses significantly enhance contrast because they block most or all blue light, which makes them good for skiing but makes them bad for any activity that requires colour recognition (like driving).

Consider the lens material.

Scratched up sunglasses are useless sunglasses. Lenses made from NXT polyurethane are impact-resistant, flexible, lightweight, and have great optical clarity, but they’re expensive.

  • Glass is heavier, expensive, and will “spider” if broken.
  • Polycarbonate is not as scratch-resistant and provides less optical clarity than NXT polyurethane or glass, but it’s more affordable.
  • Acrylic is also affordable, but it’s the least durable and optically clear.

Decide on a style.

Sunglasses come in all shapes and sizes! Here are a few popular styles:

  • Mirrorshades usually come in an aviator or wraparound shape.
  • Aviators work well with any face shape, in particular an oval shape.
  • Wayfarers/Spicolis were made popular in the 1950s and 1960s and worn by Audrey Hepburn in the 1961 movie Breakfast at Tiffany’s.
  • Teashades were popularized by John Lennon and Ozzy Osbourne and despite looking great, they’re not very effective at keeping light out of your eyes.
  • Wraparounds are great for athletes and extreme sports.
  • Oversized have long been associated with models and movie stars – they scream glamour and style
