4 Essential Features to Look for in Good Prescription Sunglasses

Your eyes deserve protection from harmful UV rays, but that doesn’t mean you should compromise on clear vision. When you need corrective lenses and want to shield your eyes from bright sunlight, prescription sunglasses become essential. 

Finding the right pair requires more than just picking frames that look good on your face. Several important features determine whether your prescription sunglasses will provide the protection and clarity you need.

Effective UV Protection 

The most critical feature of any sunglasses is complete UV protection. Your prescription sunglasses should block 100% of both UVA and UVB rays. This isn’t just about comfort on bright days. UV exposure can lead to serious eye conditions including cataracts, macular degeneration, and even cancer of the eyelid.

Look for sunglasses labeled with UV400 protection or those that specifically state they block 100% of UV rays up to 400 nanometers. Some manufacturers use terms like “UV absorption up to 400nm” which means the same thing. 

Don’t assume that darker lenses automatically provide better UV protection. The UV-blocking properties come from invisible coatings applied to the lens, not from the darkness of the tint.

Protective Coatings That Extend Life

Scratch-resistant coatings significantly extend the life of your prescription sunglasses. These invisible layers protect the lens surface from everyday wear and tear. While no coating makes lenses completely scratch-proof, they do make them much more durable.

Anti-reflective coatings reduce glare from surfaces like water, snow, or pavement. This coating is especially valuable for prescription sunglasses because it eliminates reflections from both the front and back surfaces of the lens.

Some prescription sunglasses from retailers like Pearle Vision come with additional coatings that repel water and oil, making them easier to clean and maintain. These hydrophobic coatings help water roll off the lens surface rather than forming spots that obstruct vision.

Right Lens Material

The material of your prescription sunglasses affects durability, weight, and optical clarity. Each option has distinct advantages depending on your lifestyle and needs.

• Polycarbonate lenses are lightweight and nearly unbreakable, making them perfect for active lifestyles or sports. They naturally block UV rays and resist impact better than other materials. However, they can be more prone to scratches without proper coating.
• Glass lenses offer superior optical clarity and scratch resistance. They provide the clearest vision possible and maintain their appearance longer than other materials. The downside is their weight and the fact that they can break more easily than plastic alternatives.
• Trivex lenses combine many benefits of both polycarbonate and glass. They’re lightweight like polycarbonate but offer better optical clarity. They also provide excellent impact resistance and are thinner than regular plastic lenses.

Frame Style and Proper Fit

Your prescription sunglasses should fit comfortably and securely without sliding down your nose or pinching behind your ears. The frame should be wide enough to cover your eyes completely, including your peripheral vision.

Consider your face shape when selecting frames. Round faces benefit from angular frames that add structure, while square faces look good with rounded frames that soften strong jawlines. Oval faces can wear most frame styles successfully.

The bridge of the glasses should sit comfortably on your nose without leaving marks. The temples should rest gently on your ears without creating pressure points. When you smile or move your head, the glasses should stay in place.
