Sunglasses have become a fashionable accessory that we use almost all year round,  more so in some regions than others. They may seem like an insignificant accessory, but they can turn a simple outfit into one bursting with style. Apart from their power to take any look to the next level, sunglasses are essential for protecting our eyes from ultraviolet (UV) rays that can cause irreversible damage. So, how do we know if a pair of sunglasses are good quality? What should we look for to know whether they are excellent quality and whether they will provide suitable protection for our eyes? We’re going to give you the crucial factors to ensure your fashion accessory also offers practical and functional protection for your eyes.

Keys to knowing if sunglasses are good quality and will protect my eyes

You are bound to be aware of the huge importance of protecting your eyes from the sun. But do you know why it’s so vital? Firstly, you should be well informed to ensure you buy quality sunglasses. That’s why we’re going to take a look at the key factors that will help you to make a decision. 

UV protection

Ultraviolet rays are your eyes’ worst enemy. They are a form of electromagnetic radiation that comes from the sun and, although invisible, they have a significant effect on health, including the eyes. They can encourage the development of cataracts and cause inflammatory diseases. Protecting your eyes from UV rays is essential! Some sunglasses are capable of filtering these harmful rays by 100%. Look for models with the UV400 label. This is a filter that will protect your eyes from both UVA rays and UVB rays, practically 100%. Don’t risk it and always opt for sunglasses with UV protection, your eyes will thank you for it!

CE certification

Before buying your new sunglasses, check that they have the CE certification, which guarantees the product meets European health and safety standards. This means they offer appropriate protection from UV rays, that they are made from safe materials, and they have followed controlled processes during manufacturing.

Type of lenses for sunglasses

Additionally, there are different types of lenses available for sunglasses, although this is more related to preferences than quality. We will explain the differences so you can choose the ones that best suit your lifestyle and preferences.

  • Photochromic lenses: They are incredibly practical since they adapt to the light intensity, adjusting their color. This means you won’t have to take them off each time the sun disappears for a while.
  • Gradient lenses: These lenses are ideal for situations where you want to protect yourself from the sun, but you also need to see clearly in shady or indoor conditions. The top of the lenses of the sunglasses is usually darker, while the bottom is lighter. In any case, make sure the gradient lenses offer complete UV protection.
  • Polarized lenses: Polarized lenses have a special filter that blocks out reflected light and reduces glare. You will enjoy clearer vision and suffer less eye fatigue. They are recommended in particular for situations requiring full attention for safety reasons, such as when driving a vehicle.

Filter category

Good sunglasses should allow the right amount of light through, or rather, the amount of light to suit your needs. Sunglasses are separated into five categories according to their light absorption capacity, from 0 to 4. To give you an idea: Category 0 lenses are very clear and recommended for indoor use or on cloudy days. Category 4 are the complete opposite and are recommended for extreme sports, the mountains, or beach. Bear in mind that they aren’t suitable for driving in, since they can reduce visibility too much. For any sunny day when you’re going to leave the house, we recommend sunglasses with category 2 or 3 lenses, choose them according to your personal preference.

More tips for choosing your sunglasses
