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 is important to follow the recommended wearing schedule and replace your contact lenses as directed by your eye care professional. **
