Not suitable for people who wear sunglasses1

Summer is coming, and sunglasses will become people's darling, but some people are not suitable for wearing sunglasses, do you know? 1. It is not suitable to wear sunglasses for glaucoma. After wearing sunglasses, the visible light entering the eyes will decrease, and the pupils will naturally expand, resulting in a narrow anterior chamber angle and poor drainage of aqueous humor. Over time, it is easy to induce acute onset of angle-closure glaucoma, redness, eye pain, headache, sharp decline in vision, and even systemic symptoms such as nausea and vomiting. Therefore, people with glaucoma or suspected of having glaucoma should not wear sunglasses.　　2. Sunglasses are not suitable for places with low light. Some people wear sunglasses regardless of time and occasion, whether outdoors or indoors, regardless of the intensity of the sun, and even at dusk, evening, and when watching movies or TV. Doing so will increase the burden on the eyes, cause tension in the eye muscles, blurred vision, and in severe cases, symptoms such as dizziness and inability to see for a long time, visual fatigue.　　 Children under 3 or 6 years old should not wear sunglasses.

Sunglasses with thick frames, wide edges and heavy weight tend to compress the trigeminal nerve Under the branch, which leads to sunglasses syndrome.
