If you move between indoor and outdoor environments throughout the day, transition lenses can simplify your routine. These lenses are clear while you’re indoors, then turn dark once you step outside. The secret lies in photochromatic dyes, which cause the lenses to darken in response to UV exposure. This eliminates the need to switch between prescription glasses and sunglasses throughout your day. Transition lenses are available in multiple colors, but brown and grey remain the most popular. Ultimately, choosing between brown vs grey transition lenses boils down to your lifestyle and personal preferences.
Regardless of color, transition lenses block 100% of UVA and UVB rays outdoors and turn clear once UV exposure ends. Indoors or at night, they look virtually the same. The main difference between grey vs brown transition lenses is how they influence color perception, contrast, and visual comfort.
Grey Transition lenses are slightly darker than brown, which can be beneficial for people with light sensitivity. They also maintain true-to-life color perception, providing enough dimness to keep your eyes comfortable without distorting the colors in the scene around you. Grey is recommended if you work outdoors, engage in outdoor sports, or are simply looking for the darkest transition lens available.
Brown transition lenses add a warm tint to your vision, but they also provide better contrast compared to grey lenses. This can enhance depth perception or sharpen details, even under a variety of lighting conditions. For these reasons, brown lenses are well-suited for golfers, hunters, or anyone who prioritizes visual clarity and detail over dimness.
Both brown and grey transition lenses provide effective protection from sunlight, so the best lens color for you depends on personal preference.
If performance differences don’t matter to you, many of our customers simply match the lens color to their frame style.
Keep in mind that transition lenses don’t get as dark as traditional sunglasses, and they also don’t get as dark when temperatures are higher. In addition, you may see little difference while wearing your transition lenses behind the windshield of a car. If your eye health requires you to wear dark sunglasses, speak to a physician to determine if transition lenses are right for you.
Along with choosing your transition lens color, you can now choose between different lens options, each with its own advanced features.
Transitions Signature Gen 9 offers superior clarity and darkening speed compared to previous generations of lenses. With a transition rate of 18%, measured at a temperature of 23°C (89.6°F), these lenses quickly shift from clear to sun-darkened, making them an excellent all-around choice for anyone who wants convenience and consistent performance.
Transitions XTRActive lenses are designed to provide the highest level of light protection. While clear, Transitions XTRActives can filter up to 45% of blue light, protecting your eyes from straining after long hours in front of the computer or tablet screen. Under sunlight, they filter up to 86% of the blue-violet light that heightens the risk of macular degeneration. This is the top choice for people who are highly light-sensitive or require blue light filtering capabilities.
Transitions XTRActive lenses are particularly useful for outdoor activities like hunting, fishing, skiing, and more. However, the best lens color depends on the nature of the activity. Brown XTRActive transition lenses enhance contrast in low-light environments, making it easier to spot detail in shaded areas. On the other hand, grey XTRActive transition lenses are usually better at reducing glare, making them the preferred choice for sunny days on the water or ski slopes.

If you require prescription vision correction, consider making the switch to transition eyeglasses. Transition eyeglasses combine adaptive lens technology with your custom prescription. You get clear vision indoors and automatic protection outdoors, all in one pair tailored to your style.

For industrial or workplace settings, you can further optimize your prescription and non-prescription transition lenses with safety glasses. Along with convenience and high-quality vision correction, transition safety glasses are durable enough for everyday use and available with CSA and ANSI certifications. They provide clear vision, UV protection, and durability for tough environments, making them a practical solution for workers who move between indoor and outdoor conditions.
