It can be uncomfortable to walk around in sunglasses for some people, especially if the sunglasses are too tight or heavy, causing pressure on the nose or behind the ears. Additionally, if the lenses are not the right prescription or are too dark, it can make it difficult to see clearly, leading to discomfort. However, with the right fit and style of sunglasses, many people find them comfortable to wear while walking around. **

The decision between wearing prescription sunglasses or contact lenses depends on your personal preferences and lifestyle. If you prefer the convenience of not having to switch between glasses and sunglasses, contact lenses may be a better option.

It's best to consult with your eye care provider to determine which option is most suitable for your needs. **

Polarized lenses in sunglasses are designed to reduce glare from surfaces such as water, snow, and roads. They contain a special filter that blocks intense reflected light, allowing only vertical light to pass through. This helps to enhance visibility and reduce eye strain, making them particularly useful for outdoor activities such as driving, fishing, and skiing. Polarized lenses are also effective in reducing the harmful effects of UV rays, providing added protection for the eyes. **

It's important to stay focused and maintain a safe following distance from the vehicle in front of you to ensure a smooth transition through the tunnel. **

Additionally, some sunglasses frames may not be suitable for holding prescription lenses due to their shape or curvature. **
