I use different frame sizes for different seasons. Summer outdoor activities need different sizing than winter indoor work.
For summer, I use 54-18-140 sunglasses. The larger size provides better sun coverage and works well with outdoor activities. They need to stay secure during sports and movement.
Winter means more indoor time. I use my regular 52-18-140 frames. They're comfortable for all-day indoor wear and work well with winter hats and scarves.
Optimized vision and comfort year-round by matching frame size to seasonal needs and activities.
