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.

Polarized lenses are also effective in reducing the harmful effects of UV rays, providing added protection for the eyes. **
