Monthly-wear lenses are great for those responsible enough to take good care of their lenses according to their eye doctor’s instructions. They tend to be made of sturdier material than daily-wear lenses, meaning they don’t tear as easily. The material also lets in more oxygen to the eye, preventing serious complications that can harm your long-term eye health. They are also more eco-friendly (think one lens per month vs. thirty) and are less expensive up-front.
