Your eye doctor should regularly examine any changes to your vision or eyes because certain eye symptoms can indicate the need for emergency care.
In addition, some eye conditions may not have noticeable symptoms, or they may come on very gradually. This makes it important to have regular eye exams, as many eye conditions can be effectively treated when identified early.
The following symptoms may indicate an emergency requiring immediate medical attention:
Black spots or flashes of lightCurtain-like disappearance of visionEye injury or painSeeing halos or rainbows around lightLoss of peripheral (side) visionSudden hazy or blurred visionSudden vision loss in one eyeRed, crusty or swollen eyelids
