I looked at the sunset with binoculars for 1 or less seconds by accident. can i go blind? what can happen? what should i look for as symptoms? :(

See below: Looking at the sun directly or through binoculars or a telescope without proper filters can cause damage to the retinas. See an ophthalmologist who can thoroughly examine your retinas for any damage your may have sustained. If multiple areas are involved, you may notice blind spots in your vision.

Sun gazing: It is never a good idea to stare at the sun. Your brief exposure most likely resulted in no damage to your retinas.

No: Staring at the sun or other sources of bright light can cause solar retinopathy. This is a condition where the photo-receptors in the center of the retina become damaged, limiting the visual acuity. It cannot lead to total blindness. If you have no symptoms of decreased vision at this time, i would not be concerned.
