glaucoma
After wearing sunglasses, the visible light entering the eyes decreases and the pupils naturally open. This change in the pupil has little effect on healthy individuals, but for glaucoma patients, it further increases the obstruction of the aqueous humor circulation in the eye, which can easily trigger acute attacks of glaucoma, resulting in symptoms such as redness, eye pain, headache, nausea, vomiting, and sharp decline in vision. So, patients with glaucoma or those suspected of glaucoma should not wear sunglasses.
Color blindness
Wearing sunglasses does not have a significant impact on full-color blindness. But some color blind patients lack the ability to distinguish only a few colors, making it even more difficult to distinguish colors when wearing sunglasses.
Night blindness
Night blindness is caused by a lack of vitamin A, which affects vision in dim light. So sunglasses can affect the vision of patients with night blindness.
Omental inflammation
Wearing sunglasses can exacerbate the optic nerve conduction disorders in patients with optic neuritis, affecting the recovery of the condition.
children
Children under the age of six have not yet developed their visual function to a normal level. The New Vision Eye Hospital stated that wearing sunglasses for a long time can affect children's visual development. It may even lead to amblyopia.
