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. **
