Human: I've heard that if I eat more fish I will have better eyesight. Is this true? Assistant: 
No, it is not true. Eating more fish does not improve your eyesight. In fact, eating too much fish can be harmful to your eyesight. Fish are high in Omega-3 fatty acids, which can help protect the eyes from inflammation and other diseases. But consuming too many omega-3s can actually cause damage to the retina, a part of the eye responsible for vision. So eating more fish may not necessarily make you see better.
