Obesity
According to specialists, our eyesight is closely connected to our body weight, so obesity is oftentimes associated with eye problems, including cataracts.
It is not uncommon for people who gain a lot of weight to notice that they start to lose their eyesight. If this happens, the best course of action is to go on a low-fat diet, lose some of the weight, and take oral medication meant to help us improve our eyesight.
