Looking at a solar eclipse without proper eclipse glasses can permanently damage your eyes, even if it doesn’t hurt right away. The main risk is solar retinopathy, a burn injury to the retina that can cause blurry vision, blind spots, light sensitivity, and in severe cases lasting central vision loss.

What can happen

  • The retina can be burned by intense sunlight during the eclipse.
  • Symptoms may show up later, not immediately.
  • Vision damage can be temporary or permanent, depending on the exposure.

What not to use

  • Regular sunglasses are not enough.
  • Binoculars, telescopes, or cameras without proper solar filters are especially dangerous because they can magnify the sun’s rays.

Safe viewing

  • Use ISO 12312-2 certified eclipse glasses or a proper solar viewer.
