Bicycle Sunglasses


Bicycle Sunglasses provide reliable eye protection from the harmful effects of ultraviolet rays, help to reduce eye strain in bright light and protect against flying debris and other hazards while cycling. Correct points will create a comfortable environment when driving or when doing any work, climbing a mountain or riding a bicycle.

Information about the degree of protection from the harmful effects of the external environment should be indicated on the label or price tag when buying bicycle sunglasses.

Everyday goggles: are great for everyday use and for entertainment. This type of glasses perfectly protects the eyes from the sun when you go to work and walk in the city. Such glasses, most often, are not acceptable for intense sports.

Sunglasses for sports: are used during jogging, hiking and cycling, as well as during other sports. These glasses are pretty light and are well suited for quick movements. Professional frames and lenses are made of a material that is shock resistant and flexible.

Ice glasses: are designed specifically to protect the eyes from strong light at high altitude and the sun, which is reflected from the snow. They often provide additional inserts around the rim to block the passage of light on the sides.

Characteristics of Sunglass Lenses

Polarized lenses: significantly reduce glare. Well suited when practicing water sports. Sometimes polarized lenses react with shades of windshields, creating blind spots and reducing visibility on the LCD display. To avoid this, you should use mirror lenses that reduce glare.

Photochromic lenses: automatically adapt to any changes in the conditions and intensity of light. Darken in the sun and brighten when it becomes dark. 
Warning : the photochromic process lasts longer while working in a cold environment, and it does not work at all when driving a car. This is due to the fact that UVB rays are not able to penetrate the windshield.

Interchangeable lenses: some types of sunglasses are sold with a set of interchangeable (removable) lenses of different colors. This allows you to tailor eye protection to activities and conditions. Use this type of lens for reliable protection in a variety of situations.

Passing Visible Light

he amount of light reaching the eyes through the lenses is called visible light transmission (VLT). The magnitude of the measurement is percentages, the VLT depends on the color and thickness of the lenses, the material from which they are made, and the coating.

Some general guidelines for choosing VLT based sunglasses as a percentage:

  • 0 – 19% VLT: perfect for bright light.
  • 20 – 40% VLT: can you use everywhere.
  • 40 +% VLT: suitable in cloudy weather and in low light conditions.
  • 80 – 90 +% VLT: almost transparent lenses with very dim and night lighting.

Sunglasses Colors (shades)

The choice of lens color depends on the extent to which visible light reaches the eye, how well you see other colors and contrasts.

Dark colors: (brown / gray / green) are ideal to use every day while staying outdoor.

Light colors: (yellow / gold / amber / pink / bright red) are good to use undermoderate conditions and at low light levels. They must be chosen for skiing, snowboarding and other winter sports.

Material for Bicycle Lenses

The material used for sunglasses lenses affects transparency, weight, durability and cost:

Glass: creates excellent clarity optics and scratch resistance. But it is more expensive and heavier than other materials. Glass will leave cracks that look like spiderwebs upon impact (but will not fall apart into fragments or collapse).

Polyurethane: provides high strength and good transparency of optics. Flexible and lightweight, but expensive material.

Polycarbonate: has excellent shock resistance and very good optics transparency. Affordable, lightweight and non-voluminous, less scratch-resistant material.

Acryl: is an inexpensive alternative to polycarbonate, best suited for everyday use. Less durable and optically more transparent material than polycarbonate or glass, with some image distortion.

Material for the Frames

The choice of frame, like the lens, is very important, as it contributes to ensuring the comfort, durability and safety of your glasses:

Metal: easily adaptable to the face, and less catchy material. Frames of such material are more expensive and less durable than other types. Keep in mind that the metal can heat up. Some metals include stainless steel, aluminum and titanium.

Nylon: is an inexpensive, lightweight and more durable material, unlike metal. Some nylon rims are well resistant to shock during sports. They are not regulated unless they have internal, adjustable wiring.

Acetate: this type of plastic is popular in the world of fashion glasses. Glasses with a rim of such material are not optimal for sports with high activity.

Castor-based polymer: is a lightweight, durable, non-petroleum-based material derived from a castor plant.

Simple Tips for choosing the best Bicycle Sunglasses

Here are some tips for choosing sunglasses:

  • The rim of the glasses should fit snugly to the nose and ears, but not injure them.
  • The weight of the sunglasses should be evenly distributed between the ears and the nose. Choose a lightweight frame for glasses to avoid excessive pressure on the contact points.
  • Eyelashes should not touch the rim.
  • You can independently adjust the fit of glasses or frames, bending the frame of the glasses on the bridge of the nose.
  • You can adjust the parts of the glasses that are snug to the nose, clamping them closer or farther apart.
