Do you know what the strongest muscle in your body is? You might guess the heart or the leg muscles, right? Well, the answer is very convoluted, as there are several muscle groups in our body. The extraocular muscles of the eye may be small. But their ability to carry out repeated motions is worth noting. I’ve heard it said these muscles are “100 times stronger than they need to be.” They are also referred to as the “busiest” muscles. For example, while reading a book, these eye muscles make over 10,000 coordinated movements.
