My check pair featured the ImpactX 2 Pink lens. In low mild, it stays practically clear (76%), and when uncovered to UV mild it darkens to 16%. This lens performs notably nicely off-road, enhancing distinction in brown, inexperienced, and white tones — good for path operating the place terrain visibility is essential.
The spherical lens design supplies an exceptionally broad and pure area of view, enhancing depth notion and spatial consciousness. That is particularly noticeable on technical trails and quick descents.
Rudy Mission claims the lens is nearly unbreakable. Whereas I didn’t push it to extremes, it’s clearly very versatile and resilient.
The photochromic transition is impressively quick. In actual fact, it modifications so rapidly that it’s onerous to seize the totally clear state in pictures earlier than it darkens once more in daylight.
For runners who want prescription correction, Rudy Mission gives two optical options
Answer 1: Prescription straight built-in into the lens
Answer 2: A clip-in optical insert mounted behind the lens
Throughout my testing in varied climate circumstances, the Astral Sphere carried out persistently nicely. In sunny circumstances, it typically didn’t darken fairly sufficient in vibrant sunny circumstances — in that case, the Laser Crimson or Laser Purple lenses would doubtless be a more sensible choice.
In overcast climate, forest trails, and even evening runs, the lens carried out excellently. Fogging was by no means a difficulty, even throughout wet runs, and water droplets rapidly rolled off the lens.
With a width of 143 mm and a lens top of 58 mm, protection is superb. Wind safety is superb, and I by no means skilled watering eyes.
I have not been capable of check the glasses within the excessive mountains but, the place you are more likely to encounter vibrant daylight. Maybe the truth that they do not get very darkish may very well be a slight drawback there.

The Rudy Mission Astral Sphere is a premium pair of efficiency sun shades that delivers on practically each entrance. Whereas the value displays its high-end positioning, you actually get what you pay for.
The glasses sit comfortably, keep firmly in place whereas operating, and provide glorious air flow. The adjustable nostril pad permits for fantastic tuning, whereas the light-weight building ensures long-term consolation.

Whereas the shortage of interchangeable lenses is likely to be a draw back for some, it additionally contributes to the lens’ sturdiness and suppleness. With a number of lens variants accessible, there’s an appropriate choice for nearly each athlete and surroundings.
