What is a polarised sunglass?

Polarised sunglasses are a specialized type of eyewear designed to reduce glare from surfaces such as water, snow, and glass. Glare distorts the true color of objects and makes them harder to distinguish.

Because of this, polarised eyewear can be useful for certain sports and driving, helping participants to see more clearly and avoid potential hazards.

What are the advantages and disadvantages of polarised glasses?

The advantage of this type of glasses is that its lenses are coated with a special chemical film that helps reduce glare, this way you are able to see more clearly. In addition, it helps to reduce the harmful effects of UV light.
However, these types of sunglasses do get in the way when it comes to looking at digital devices. It is very difficult to watch TV, take a selfie or even check an LED monitor with these glasses.

So if you work looking at screens frequently while out and about, regular sunglasses might be a more appropriate choice. Also, they can be dangerous for skiers, who need to distinguish between very similar surfaces.

  • Useful for driving and sports
  • Perfect for water environments and snow
  • Protects from UV rays
  • Hinders looking at digital devices
  • Can be dangerous for skiers

What are the types of polarised lenses?

Now that you know a little bit about how polarised lenses work, check out the types of lenses available on the market and choose the right one for your needs. The two main models of polarised sunglass lenses are:

  • Polarized 0.75mm lenses: If you are more of a casual person who enjoys outdoor sports, 0.75mm lenses are ideal for you. Great for everyday activities, these polarized lenses are made of thin sheets of polarized film, which are a great option to protect in a moderate way from the sun's rays.
  • 1.1 mm polarised lenses: If you are an outdoor sports enthusiast or have a little extra cash to spare, a good tip is to invest in a model with more advanced lenses. Although made with thicker sheets of film, these lenses offer a better result, although they have the same polarization layer.

Polarised or non-polarised sunglasses: which is better?

While sunglasses are great for reducing glare from sunlight, just imagine conducting a reading outside during the summer and you'll find that they don't necessarily eliminate the hassle of sunlight.

Don't let the average sunglass fool you. Just because they are dark does not mean they offer good protection against UV rays. Polarised sunglasses, on the other hand, offer far more complete protection for your eye.

Ordinary lenses basically only reduce the amount of light reaching your eyes, which is definitely helpful, but may not be the perfect solution for water sports or a round of golf, for example. In these cases, polarised sunglasses are much more suitable.

However, sunglasses with normal lenses exist in many more models and types, as well as being cheaper. Polarised sunglasses can be found in a slightly smaller, but still very good, variety of models, however, with much higher prices.

Polarized sunglasses Ordinary sunglasses
Indication Long-term outdoor activities, water sports, golf, etc. Sunny days without long exposure to the sun
Contraindication Use of electronic devices with LED and LCD screen and snow skiing Prolonged exposure to the sun and outdoor sports
Price More expensive Cheaper
Variety Few models Many models available

How to know if your lenses are polarized?

Sunglasses are often sold as if they are polarized, when in fact they do not have the correct protection. You can prevent this kind of scam by testing your lenses and checking that they are indeed polarised.

There are two easy ways to check if your lenses are really polarized. The first is by looking at a digital screen, such as a phone or dashboard in your car, you will immediately see a rainbow on it.

The second way is to look at the sun. If your vision does not show smudges or blurs when looking at the sun, your sunglasses are polarised.

How much does a polarised sunglass cost?

Polarised sunglasses come in a variety of models and prices, so how much you will pay for your glasses depends on many factors. The more elaborate and specific for your practice the polarised sunglass is, the more expensive it will cost.

The simplest versions of polarised sunglasses cost around £60 to £200. However, these models are usually suitable for lighter activities, which do not have much impact and usually have a thinner filter film.

If you are looking for a more elaborate sunglass, specific for your sports practice, you will probably have to pay a little more for it. These models can range in price from £150 to £500, depending on the make and model of sunglasses.

Finally, if you are looking for a branded polarised sunglass, you will have to pay even more. There are options of famous brands, such as Gucci and Prada, which can cost more than thousand pounds.

Buying Criteria: How to compare polarised sunglass models

Now that you know a little more about how polarised lenses work and know the indications and contraindications of this type of sunglasses, it's time to pay attention to some criteria that are essential when buying a polarised sunglass.

This will ensure the safety and health of your eyes and an improvement in the quality of your outdoor activities. Check out some of the most important criteria to pay attention to when buying a polarised sunglass that is perfect for what you want.

Below, we will detail each of these items so you can choose the best-polarized sunglass available on the market.

Lens color

Many people believe that the darker the lens of your polarised sunglass, the better the protection for your eyes. But this is not true. The colour or darkness of your lens is a personal preference and often based on the activity you are doing when wearing sunglasses or the conditions of the sun.

At the beach, for example, you are subject to more reflective light and it may be best to choose polarised sunglasses with dark amber, copper or brown lenses. If you are in the snow when the sky is cloudy, you may prefer yellow or orange lenses to increase contrast.

UV protection

While owning the darkest lenses doesn't mean better protection for your eyes, controlling exposure to UV radiation does. Research has found that extended exposure to UVA and UVB rays can result in eye damage.

That's why it's important to wear sunglasses that block these harmful rays, so that your eyes stay healthy as you age.

So always look for sunglasses with seals that indicate good UV protection, preferably those with 100% protection.

Face Shape

Polarised sunglasses are not just for protection, they are also a fashion item and part of a person's style. So while you want your sunglasses to provide the best UV coverage, you will also want to look good in them.

So choose the perfect model for your face shape. Check out a simple guide below to make your choice easier.

  • Heart-shaped face: Square, retro or cat-eye frame format;
  • Round face: Retro, cat-eye, square, angular or rectangular frame;
  • Oval face: Polarised sunglasses frame square, aviator, oversized, butterfly or heavier models;
  • Square face: round polarised sunglasses or aviator.


Not all light hits your eyes directly in front. It can enter from the top, sides, and bottom of your glasses.

The smaller the size of your glasses, the more unfiltered light will enter your eyes. Therefore, go for larger frames that cover your eyes entirely, with some slack.

Whatever frames you choose, make sure they fit properly and don't slip down your nose or fall out during physical activity.
