How the Solar Eclipse Lenses Protect Your Eyes from the Sun

Every year, Pakistan gets to witness at least one solar eclipse. Though people in Pakistan know about the potential danger, it presents to the eye, and they hardly take any precautionary measures. A solar eclipse can only be viewed using a solar telescope or special filtered glasses.

Looking at a solar eclipse without any protection or with substandard sunglasses can cause retinal burns or “eclipse blindness.” The intense light from the ring of fire damages cells in the retina. This damage can be permanent or temporary, and it occurs without any pain.

If you wish to view the solar eclipse, it is strongly suggested that you buy eclipse viewer glasses from vendors or manufacturers that have been approved by the government authorities.

Here’s how strong rays from the eclipsed sun can damage your eyes:

    1. UVB Rays

These rays can cause damage to the outer cells of the cornea as it constitutes the protective surface of the eye. It can result in blurred vision and may cause pain.

    2.UVA Rays

They can damage the eye’s lens and harm the retina and macula, resulting in macular degeneration and permanent blindness.
