There is a lot of terminology we use in the optical industry that is confusing; UVB? UV400? Mirrored? PD measurement? RX? What are polarized sunglasses?
The latter being one of the most popular questions; Are polarized sunglasses better than standard sunglasses?
So to begin with, I'll start with the simple explanation as to what they are, why they are better, what are the implications/downsides and lastly how are they made.
What are Polarized Sunglasses for; are they Better?
Polarized Sunglasses have one key purpose; to reduce glare from reflective light.
Whilst standard sunglasses will reduce direct sunlight and (should, if they're any good,) provide UVA/UVB protection - Polarised Sunglasses go that one step further by reducing glare from reflective surfaces such as water, snow, ice, glass, roads etc.
The end result is an overall increase in clarity of vision. A user will notice crisper edges and higher definition vision by blocking glare there didn't even know was there
Where should you use them?
Polarized Sunglasses are perfect for driving, in the snow or sailing or any activity where there is a high chance of reflective surfaces.
Drivers will see benefit, where often bright glare from mirrors and passing windows can cause distraction and limit visibility.
In winter months, Snow is just one big reflective surface! Polarized Sunglasses are perfect for life on the piste.
Sailors will also see benefit - water is a highly reflective surface, so polarized sunglasses are a must for those sunny sailing days.
Where not to use Polarized Sunglasses - FreshforPandas Sunglasses are fine to use in water, however should be dried and not soaked for prolonged periods. This goes for any brand of sunglasses with polarized lenses. Saltwater is a known corrosive that can damage the film polarisation layers, so be sure to give them a quick wipe after a dip in the ocean.
Also, be weary around Gas (Petrol) Stations; petrol, and other hot based gases are also known to impact lenses. Don't leave them on top of a speed boat engine, for instance.
Another area Polarized lenses may not be suitable is for pilots. The lenses work by filtering out light at certain angles. Airplane dials are often polarized as standard, so there is a risk dials and displays will appear blacked out if both the dials and the sunglasses provided polarization (double polarized)
Can Prescription Sunglasses be Polarized? - Yes they can be, but this is dependent on the prescription you have.
Polarized Sunglasses work by blocking out light in certain angles. When prescription lenses are glazed, the lenses are basically bent and cut so that light is re-focused. Therefore, certain strong prescriptions cannot benefit from Polarization as this conflicts with the angles of light being blocked.

How to care for Polarized Sunglasses
Polarized Sunglasses, especially when coupled with other layers such as mirror or anti-reflective coating, need certain care. They incorporate multiple layers of delicate film that can react to certain conditions.
How to Clean Polarized Sunglasses - Do not use alcohol based cleaning substances, such as standard eyeglass cleaners. These contain harsh chemicals that will react to the polarized filter layers. The lenses should be cleaned with the FreshforPandas microfibre cleaning cloth provided, using warm water with a touch of washing up liquid.
