Best sunglasses for the Northern Irish weather

when you ride a bike in Northern Ireland, you never know what the weather is going to be like. Very often you can't see much with normal or good sunglasses because it is too dark (going though a wood or cloudy day). These adapt to the light and are at an excellent price.

These are really light and grip well so they don't slip down your nose. You can pay significantly more for photochromic sun specs but I'm always worried I'm going to lose an expensive pair and being photochromic they are great no matter what the weather. Only had these a short time but bought them to replace some the same that I've had for years.

Excellent value

These glasses are light and comfortable with excellent optics and you hardly notice you are wearing them. They give clear vision in all conditions without any glare or the internal reflection you sometimes get from mirrored lenses. The nosepiece is adjustable so you can position the upper frame out of your line of vision. My only small criticism is that the arms are quite straight and bulky once they pass over the ears (rather than continuing to curve around towards the back of the head) and despite being flexible enough to bend to shape, they interfere with my helmet which pushes them forwards on my face and down my nose. If the earpieces were slimmer at the end of the arm this would be less likely to occur. Despite this, they are great value for money and a worthy alternative to many brands more than twice the price.

Lamination paper of glass came out in 1 yr 9 months. Decathlon replaced it!!! Apart from this everything perfect, may it be style, fit, darkening 9n exposure to bright light. Excellent UV protection. No eye fatigue even at high altitude bright sun long rides. Go for it.

Hi Anil,

Good Afternoon,

Thank you for taking time out to provide us your valuable feedback, this helps us improve continuously.

Could you please elaborate on the concern, when was this product purchased & the usage of the product, so that we can find a solution together to your concern.


Coating Peeled Off

The coating peeled off after very less use. The sunglasses are as good as clear glasses without the coating. Hoghly dissapointed.

Additional Product Information



  • 100% Polyamide 12


  • 70% Polyamide 12
  • 20% Rubber - Thermoplastic
  • 10% Stainless steel


Category 1 to 3 photochromic lenses: filter varying from 15% to 55% of the light at 73°F. In cold weather (below 50°F), tint change is considerably slowed down. ISO 12312-1 standard. Full UV protection filter Material: impact-resistant polycarbonate. Geometry: spherical 7-base

Photochromic technology

Photochromic lenses automatically adjust to light intensity. The lens changes tint in about 30 seconds (45 seconds to clear). The brightness feeling varies little, even if the outside brightness changes. For example, when cycling, the change in tint is hardly noticeable. The tint transition is smooth so that the eye can adjust at the same time. A cold temperature will activate (shade) the lens more rapidly.


Frame material: polyamide. Nose pads material: impact-resistant polycarbonate. Arms material: Full UV protection filter. Arm tips material: impact-resistant polycarbonate. Size: suitable for all types of face (narrow to large).


Case material: EVA, zipper fastening. Cloth material: polyester.
