Glaucoma

When wearing sunglasses, the amount of visible light entering the eyes decreases and the pupils open naturally. This change in the pupil has no effect on healthy people, but for glaucoma patients, it also increases the obstacles to the aqueous humor in the eye, which can easily induce acute attacks of glaucoma, red eyes, eye pain, headache, nausea, vomiting, and sharp vision loss And other symptoms. Therefore, patients with glaucoma or suspected glaucoma should not wear sunglasses.

Color blindness

Full color blind people wear sunglasses without much effect. However, some patients with color blindness lack the ability to distinguish only a few colors, which makes it even more difficult to distinguish colors when wearing sunglasses.

Night blindness

Night blindness is caused by a lack of vitamin A, which causes vision to be affected in dim light. So sunglasses will affect the vision of patients with night blindness.

Omentitis

Wearing sunglasses will aggravate the optic nerve conduction disorder in patients with optic neuritis, and affect the recovery of the disease.

Child

Visual function in children under the age of six has not yet developed to normal levels. New Vision Ophthalmology Hospital said that wearing sunglasses for a long time will affect children's visual development. It may even cause amblyopia.
