Cycling Glasses Materials – What Makes Them Safe?

When you are out cycling, one of the most important pieces of safety equipment that you can wear is a pair of cycling glasses.

What are cycling glasses made of that makes them safe?

Materials Used In Cycling Glasses to Maximize Safety

Good cycling glasses don’t shade the eyes like normal sun glasses. They are built to be strong and light and able to protect the eyes from UV rays and impacts.

Cycling glasses use some special materials to ensure your eye safety including:

  • Polycarbonate or acetate frames
  • Silicone nose and ear pads
  • Polycarbonate lenses (optical grade, injection-molded, polarized)
  • Anti-Reflective Coatings
  • Unobtainium or silicone temple tip covering
  • High nickel forged or machined hinges
  • Stainless steel hinge spacers and screws

All of these materials combined with good design features create enhanced safety for cycling glasses, including:

  • Photochromatic lenses (reduce glare and increase visual contrast, automatic lightening or darkening when light conditions change)
  • Hydrophobic and oleophobic lenses (repel water and oil so you can see better)
  • Anti-smear lenses
  • UV400 protection (protect up to 100% of harmful UVA and UVB ultraviolet light of wavelengths up to 400 nanometers)
  • High flex anti-fatigue frame
  • Impact-resistant lenses (to protect from rocks, dust and projectiles thrown up by other bikes or cars)
  • Light weight
  • Secure fit (eliminates need to adjust your glasses while riding)
  • Good ventilation
  • Scratch resistance (image quality does not degrade over time as quickly)
  • Enhanced peripheral vision
  • Shatterproof
  • Impact resistance
  • Anti-reflective

The frame material you choose will have a big effect on how strong your glasses are. Cheap glasses made from weak materials will not provide the eye protection needed.

Whether you go with polycarbonate or acetate frames is personal preference. Polycarbonate frames are strong, flexible and lightweight. However, polycarbonate has low scratch-resistance, so an additional hardening layer is generally added. Acetate frames are more rigid and scratch-resistant, but are often heavier.

Scratch-Proof Cycling Glasses

There is no such thing as an entirely scratch-proof pair of glasses. However, an additional clear coating can be added to lenses on the front and back that will make them more resistant to scratching. whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel. If you have kids that ride bycicels, having them wear scratch and impact resistant cycling glasses will help keep them safe along with a helmet.

Clear Cycling Glasses With UV Protection

Cycling glasses worth their salt will have complete protection from UV rays (UVA and UVB). The package will have UV400 protection listed. This means that the glasses are protected from the sun’s rays to 400 nm. These are ideal for riding bicycles in any outdoor climate during the day.

Photochromatic Cycling Glasses

Photochromic lens sunglasses offer different shading according to the intensity of the UV lights. The coloration on the lenses will change depending on the weather, such as dark and cloudy, sunny, or even in your home at night. As the colorization of the lenses changes, your perception of surrounding colors will not be interfered with.

Cycling Glasses Impact Resistance

Choosing cycling glasses with impact resistance is a good thing to do because you want to keep your eyes as protected as possible. While riding, you could be behind a car that kicks up small rocks, or near trees that drop materials onto the roadside in a stiff breeze. Impact resistance glasses also protect your eyes if you run into something or fall of the bike. Materials that offer impact resistance for cycling glasses include:

Some cycling glasses may even meet or exceed ANSI Z87.1 standards for impact resistance. Check the brand and product before purchasing if this is what you are looking for.

Anti-fog Cycling Glasses

Polycarbonate lenses offer fog reduction for riders. Anti-fog lenses can also reduce scratches and glare from the sun. However, even anti-fog cycling glasses can be prone to fogging up in certain circumstances. Having cycling glasses fog up could spell disaster for the rider while on a busy or hazardous roadway.

Cycling Glasses With Glare Reduction

Glare reduction is important for cyclists because it means the sun’s rays or excess light that bounces off surrouding objects will not be a distraction. This will enhance your safety on the road by allowing you to more easily and comfortably spot obstacles in your way. This type of protection is enhanced with AR coating (anti-glare) that is a microscopic layer that prevents front and back reflections on eyeglass lenses.

Cycling Glasses Design – Protecting the Rider

The design of cycling glasses plays a crucial role in making them safe, comfortable, and not a hindrence on the performance of the rider. Some common design features of cycling glasses include:

  • Full-rim aerodynamic frame.
  • A semi-rimless shape reduces weight and increases comfort.
  • Wraparound design protects against wind and glare.
  • Adjustable fit using spring hinges.

Some popular brands of cycling glasses include:

  • RockBros
  • Oakley
  • HUBO
  • Xiyalai

Cycling Glasses Frames

Cycling glasses frames are wrap around and aerodynamic to keep the rider’s face sleek with low drag. Frames are usually made of plastic, acetate, or acetate with plastic. Rubber ear pads may also be included on the temple tips along with a stamped or painted logo on the temples.

Acetate is a common material used to make glasses. Acetate is durable and most likely not going to irritate the skin or cause allergic reactions (hypoallergenic). Acetate plastic if formed from plant material that is made using a special technique. This means that acetate is a renewable material and is eco-friendly. Acetate is also easy to colorize so manufacturers can offer a wide array of glass frame colors to users.

You should choose cycling glasses that are very strong and that will protect your eyes from any debris or wind that might hit your eyes while you are riding. Your vision is vitally important both on and off the road to see obstacles and avert them. Good cycling glasses will keep your face and vision safe while also not interfering with your ability to ride at your chosen pace.
