In general, decorative contact lenses can cause certain harm to the eyes.

Long-term wear of decorative contact lenses can block oxygen from entering the eyes, leading to corneal hypoxia and possibly causing corneal inflammation. If decorative contact lenses are not properly cleaned and disinfected, the risk of eye infections may increase. Additionally, the curvature and material of decorative contact lenses may not suit everyone's eyes, and prolonged wear may cause corneal abrasion and even lead to vision loss. Moreover, decorative contact lenses may interfere with the eye's natural tear circulation, resulting in dry eye syndrome.

It is recommended that decorative contact lens users purchase high-quality products from reputable sources to ensure their oxygen permeability and comfort. Strictly adhere to the recommended wearing time and avoid wearing them continuously for extended periods. Properly clean and store the lenses, and replace them regularly. If any eye discomfort occurs, discontinue use immediately and seek medical examination. Regular eye examinations should also be conducted to monitor ocular health.

In daily life, it is advisable to choose reliable, suitable products and follow the instructions carefully for proper wearing and cleaning.
