This is because daily contact lenses generate more waste due to their single-use nature, leading to more plastic waste being produced. Monthly contact lenses, on the other hand, are used for a longer period of time before being replaced, resulting in less overall waste. Additionally, monthly contact lenses typically come in less packaging compared to daily lenses, further reducing their environmental impact. **

Ultimately, the better option will depend on factors such as lifestyle, activities, and personal preferences. **
