Are Photochromic Lenses Worth It?
Photochromic lenses automatically adjust their tint depending on the available light. For many riders, this gives one pair of glasses the versatility of several fixed-tint lens options.
Variable-tint photochromic lenses
These remain tinted but become lighter or darker depending on available light.
- Road cycling
- Gravel riding
- Long mixed-weather rides
Tinted-to-clear photochromic lenses
These transition from a dark tint in bright sunshine to almost completely clear in low-light conditions.
- Mountain biking
- Woodland trails
- All-day adventures
For UK mountain biking in particular, tinted-to-clear lenses are especially useful. Many rides move repeatedly between bright open sections and darker woodland trails, allowing the lenses to adapt automatically as conditions change.
Cycling Eyewear FAQs
Here are the questions riders most often ask when choosing cycling glasses, sunglasses and MTB goggles.
What colour lens is best for UK riding?
There is no single best lens colour for every rider, but amber, orange and photochromic lenses are particularly popular because they perform well in mixed weather and changing light conditions.
Are photochromic lenses worth it?
For many riders, yes. Photochromic lenses adapt automatically as light conditions change, reducing the need to carry or swap lenses during a ride.
Are photochromic lenses suitable for mountain biking?
Yes. Tinted-to-clear photochromic lenses are especially useful for mountain biking because trails often move between bright open areas and darker woodland sections.
What is the difference between cycling glasses and sunglasses?
Cycling glasses are designed primarily for riding, with secure fit, coverage, ventilation and lens options for different conditions. Casual sunglasses are more lifestyle-focused and work well for relaxed riding and off-bike use.
Should I choose riding glasses or goggles for mountain biking?
For cross-country and trail riding, most riders prefer riding glasses because they are lightweight and well ventilated. For enduro racing, downhill riding and bike park laps, many riders prefer the extra coverage and protection offered by goggles.
Can I wear cycling glasses at night?
Yes. Clear lenses are designed for low-light and night riding, providing protection from insects, debris and wind without darkening your view.
What is VLT?
VLT stands for Visible Light Transmission. Higher VLT percentages allow more light through and are better for low-light conditions. Lower VLT percentages are darker and better for bright sunshine.
Are polarised lenses good for cycling?
Polarised lenses can reduce glare and improve comfort in bright conditions, making them useful for road riding, leisure cycling and commuting. Some riders prefer non-polarised lenses for technical off-road riding where reading subtle terrain detail is important.
Are expensive cycling glasses worth it?
Premium eyewear often offers better optical clarity, more advanced coatings, improved fit and higher-quality lens technology. The most important thing is still choosing eyewear that fits well and suits your riding conditions.
