Eyes are windows to the sole, or any other fish for that matter. Look for clarity and brightness. You’d be wary of a date with dull and lifeless eyes, right? Expect no less of your fish. Not that it should be winking back at you but, a fish with cloudy eyes is an indication that it is well past its prime. Your fish should also have bulging eyes. Eyes that are sunken reveal a dehydrated fish, which means it spent more time on ice than in the water before you made your purchase.
