2. Ocular defects obstructed
3. Can reduce the regulatory burden on the ciliary muscles of the eyes under strong light
4. Block harmful light
4. Protect your eyes from harm
5. Wearing sunglasses will make your face look thin. This theory was proposed by the Olsen sisters, and her theory is very simple. Women who love beauty and thinness always "deliberately" make themselves look smaller and slimmer. The larger the sunglasses worn on the bridge of the nose, the smaller their face will look, creating a visual effect of "slimming face".
