Sunglasses are the most effective defence against UV rays .. but not all glasses offer the same protection. 90% of people don’t care about this aspect and very often don’t know if their sunglasses protect them from these rays so harmful to the eye.
With this article you will receive the essential information to be able to choose your new sunglasses in the best possible way, ensuring total protection from UV rays, but let’s go step by step.
What are UV rays?
Ultraviolet (UV) rays is a powerful electromagnetic radiation. They are not visible to the human eye, represent only 5% of all light emitted by the sun, but despite this .. you can’t really underestimate them!
They are divided into 3 types:
- UVA rays: represent 95% of the UV radiation that reaches us. They are present all year round, even on cloudy days. They have a powerful action going deep and are the main cause of the production of free radicals, that caused cellular aging.
- UVB rays: represent 5% of the UV rays reaching the earth. They are responsible for the tanning and the related problems to a lack of protection (sunburn). As UVA rays are a danger to our eyes, if not properly blocked. It’s so important to be aware of this information and make sure a total protection from UVA and UVB rays.

Lens colour is a protection factor against UV rays?
Absolutely not … this is a fake information that many people unfortunately believe. There is no relationship between lens colour and UV protection, and darker lenses don’t necessarily give you more protection. The colour of the lenses can improve your comfort and have a screen effect on the sunlight we perceive, but nothing to do with UV rays that are invisible to the human eye. However, it is very important to choose the type of lens that best suits your needs in order to have the ideal comfort, visibility, style and safety.

Why is it so important to protect yourself from UV rays?
As you may have guessed, we often don’t know the damage that exposure to the sun can cause to our eyes.
Prolonged exposure without protection could compromise the health of your eyes causing redness, tearing, hypersensitivity up to more important problems such as cataracts or macular degeneration. The dangers are different and also affect the skin and are the main cause of premature aging in the eyes area, sensitive and very vulnerable zone.

The 5 basic UV protection rules before choosing your new sunglasses
If you are thinking of buying a new model of original and fashion sunglasses, I recommend you to follow these simple rules to avoid running into a low quality product and not able to provide you the right protection you need:
- Always buy your sunglasses from an authorized optician or shop. Be wary of unreliable retailers, markets, stalls or unauthorized persons.
- Make sure your sunglasses model has 100% UVA and UVB certified protection.
- Improve protection by choosing a suitable frame. Sunlight can reach our eyes from above or to the side. For optimal protection you can choose frames with wide temples and large lenses.
- If you are buying online, always be wary of branded sunglasses sold at bargain prices. Surely you can find good quality low cost models, but a branded product at too low price is difficult. Even if you are looking for an opportunity, be aware!! It is important to check the brand’s website, check the product features and buy at a reasonable price.
- Check the protection with a simple home test using a small torch or UV light (you can also easily find them online). Simply project the light on the front lens (from where it receives the sun’s rays) and check that the UV light beam does not exceed it. This will be the ultimate proof of total protection.
