Optimizing eye protection: Choosing right sunglasses amid rising temperatures

With the heat wave and rising temperatures, protecting your eyes is essential, especially when you need to go outside. While affordable sunglasses from supermarkets and online retailers often meet basic UV protection standards, their overall quality, including visual clarity, can be subpar.

Opticians, regulated by national health standards, provide a more reliable option. Sunglasses sold by professional opticians typically bear CE and UKCA marks, indicating they meet higher safety and quality standards. Opticians can also help you choose sunglasses that offer the right combination of protection, comfort, and style. European law classifies sunglass lenses as “personal protective equipment,” with five levels of protection. Category 3 lenses, the most common, are suitable for various conditions, including driving. Darker lenses do not necessarily offer better protection, as the appropriate category depends on the intended use.

Understanding visual acuity, contrast sensitivity, and lens material can help in choosing the right pair. Visual acuity measures how sharply we see, while contrast sensitivity is the ability to distinguish objects from their background. Plastic (organic) lenses are lightweight and durable, suitable for everyday use. Glass (mineral) lenses offer better scratch resistance, color fidelity, and visual clarity.

When choosing sunglasses, consider more than just UV protection. Opt for sunglasses that meet safety standards and provide good visual clarity and comfort.

Consulting with a professional optician can ensure that you get the best protection and quality for your eyes.
