Lenses have small microscopic pores that are not visible to use. Over time, these pores become hard and clogged(when you don’t clean them regularly or replace as direct by an eye specialist). The bacteria accumulated in the lenses can cause serious damage to the eyes. This is why doctors recommend changing lenses at regular intervals. Also, avoid wearing contact lenses for too long. Your eyes need some rest and oxygen that you should give.
