An annual eye exam is about more than just preserving your healthy vision. Your eye exam can also be an integral first step in helping you manage or even improve your overall health and well-being. For example, did you know your eye exam can identify warning signs of serious health conditions like diabetes and high blood pressure? They’ve even been used to discover brain tumors. Discovering these conditions during your eye exam means treating them sooner rather than later, when the problem may have grown more serious and the treatment more expensive.
