Why do my eyes hurt after the eclipse?

There are two main reasons why your eyes might hurt after viewing a solar eclipse without proper protection:

1. Solar Retinopathy: This is damage to the light-sensitive retina at the back of your eye caused by looking directly at the sun. The sun emits intense ultraviolet (UV) light, which we can't see but can damage our eyes. Unlike our skin, which can tan to protect itself from UV rays, our eyes don't have this defense mechanism.

• While we have natural reflexes like blinking and pupil constriction to shield our eyes from bright light, these aren't enough to protect against the sun's intense light during an eclipse.
• Symptoms of solar retinopathy can appear within hours or even days after sun exposure and may include:
  • Blurry vision
  • Pain or discomfort in the eyes
  • Seeing dark spots or floaters
  • Light sensitivity
  • In severe cases, permanent vision loss

2. Corneal sunburn: This is similar to a sunburn on your skin, but it affects the cornea, the clear dome at the front of your eye. While less common than solar retinopathy, it can still cause discomfort.

• Symptoms of corneal sunburn, also known as photokeratitis, can appear quickly after sun exposure and may include:
  • Pain or scratchy feeling in the eyes
  • Sensitivity to light
  • Watery eyes
  • Blurred vision

If you're experiencing any of these symptoms after viewing a solar eclipse, it's important to see an eye doctor as soon as possible. Early diagnosis and treatment can help prevent permanent vision damage.

Here are some additional things to keep in mind:

• Looking at a partially eclipsed sun is just as dangerous as looking at a full eclipse. Even a small amount of sunlight can damage your eyes.
• Never look directly at the sun, even for a brief moment, without proper eye protection. Solar eclipse glasses with specific certifications are essential for safe viewing.
• Using sunglasses, regular eyeglasses, or homemade filters is not safe for viewing a solar eclipse. These don't provide adequate UV protection for your eyes.

By understanding the risks and taking proper precautions, you can enjoy the wonder of a solar eclipse without putting your eyes at risk.
