They can protect your eyes from glare differently, and they also can help you see some items more clearly. Which one proper for you depend on where you will be using your sunglasses, and your own eyes. Blue tints are best for partly cloudy or even sunny situations. They allow the maximum amount of available blue light, and are often used in sunglasses for tennis, shooting in certain situations, winter sports, and even golf. While rose and pink tints give the highest contrast of all the tints, and give great low-light resolution. They are excellent for high-contrast sports like skiing. You can prepare different sunglasses for different occasion.
