It is possible to wear sunglasses for cataracts because wearing sunglasses does not aggravate cataracts and does not affect serious eye problems. Cataracts are mainly caused by cloudy crystals and can be caused by trauma, systemic metabolic diseases, such as diabetes, or age-related cataracts.
In general, cataracts can be observed when they are mild because they do not affect vision or have a relatively small impact on vision. If it develops into a moderate or severe cataract, which affects vision more, or if it is obvious that you feel a significant blurring of vision, then surgery should be considered. However, regardless of the type of cataract, sunglasses can be worn before or after surgery. It will not cause the cataract to worsen or affect the severity of visual function.
