1. Lens color: Wearing sunglasses with dark lenses (too low visible light transmittance) in daily environments (such as indoors) for a long time can cause visual fatigue and severe symptoms such as dizziness and nausea.
2. Sunglass frames: For example, the temples are worn too tightly, pressing the temples, causing dizziness, or it is caused by the discomfort of wearing the stipules of the glasses.
3. Lens processing problem: Sunglass lenses have no luminosity (except for myopic sunglasses), but if the size of the lens is too large during processing, it will be forced into the frame. Under the stress of such long-term distortion, the optics of the lens The indicator will therefore exceed the standard. Wearing such lenses can cause dizziness to be dizzy, and vision can be affected in severe cases.
In addition to the above, it is not ruled out that some people feel uncomfortable with progressively dyed sunglasses lenses.
The End
Thanks for your attention
