With the first signs of Spring upon us, you might be thinking of investing in some new sunglasses. Here's 10 things you might want to consider for use at sea:
1. Polarised lenses: filter horizontally reflected light, so are ideal on the water.
2. Floating frames or at least floating retaining strap.
3. Hydrophobic and scratch-resistant outer coating to repel water.
4. Oliophobic inner surface coating to repel sweat etc.
5. Colour: Grey is best for colour recognition (CRI), whereas brown or gold are considered better for contrast.
6. Polycarbonate lenses offer good impact resistance, but clarity of optics is not as good if you have Rx lenses.
7. Close fitting wrap frames offer better protection from the wind and periphary glare/UV.
8. UV 400 lenses cut out harmful UV rays across the entire spectrum.
9. Sunglasses dont have to be marine-specific, but many of the above features will be included if they are.
10: If you are budget conscious, prioritise features over branding, as there are some good value unbranded options available, whereas cheaper branded options will be very basic.
Happy when wet!
