Due to my extremely sensitive eyes, I can only wear lenses for one day. These lenses are pleasant to use and do not contribute to dry eye syndrome. For the purpose of the experiment, I wore the same set of glasses on the second day. The feelings were more intense, and I had some blurriness; however, the lens did not shatter, and it disappeared after a half day. It is better not to do this, and you cannot save money on your health by doing so; you must replace your daily disposable lenses every day. I recommend lenses.
