The sun’s rays are immensely powerful and looking directly at it, even during an eclipse, can cause permanent damage to the retina, leading to a condition known as solar retinopathy. The danger is heightened because there’s no immediate pain when the damage is being done, and the loss of vision can be either temporary or permanent.
Direct viewing of the uneclipsed or partially eclipsed sun is only safe through special-purpose solar filters, such as “eclipse glasses” or hand-held solar viewers. Regular sunglasses, even very dark ones, or homemade filters are inadequate as they allow thousands of times too much sunlight to pass through, posing a significant risk to one’s eyesight (NASA Eclipse Safety).
Certified Protection Standards
For the utmost protection during an eclipse, individuals should use products that comply with the ISO 12312-2 safety standard. This includes ISO-certified eclipse glasses and viewers, which are designed to filter out harmful solar radiation effectively. If these filters are not scratched, punctured, or torn, they can be used to observe the uneclipsed or partially eclipsed sun for as long as desired. Moreover, contrary to outdated warnings, these compliant products can be used indefinitely and do not have a viewing time limit or expiration date, as long as they maintain their integrity and are stored properly (NASA Eclipse Safety).
The American Astronomical Society provides a list of reputable vendors that supply solar filters and viewers meeting the ISO 12312-2 international safety standard. Ensuring that any product used for eclipse viewing is sourced from these vendors can greatly reduce the risk of eye injury (NASA Eclipse Safety).
Safety when observing a solar eclipse cannot be overstated. Using the appropriate filters, such as shade 14 glasses or welders glass for eclipse viewing, is essential. Adhering to the guidelines set by safety standards will ensure that the experience of watching a solar eclipse is not only memorable but also safe.

Other Safe Viewing Methods
While welders glass for eclipse viewing is a popular method, there are other safe ways to observe a solar eclipse. Understanding these alternatives is crucial for anyone interested in astronomy and eclipse events.
Pinhole Projection Technique
The pinhole projection technique is a simple and safe way to view solar eclipses without looking directly at the sun. It involves projecting the image of the sun through a small opening onto a flat surface, effectively creating a miniature version of the eclipse. This method can be improvised with common items, such as a piece of card with a small hole or even the gaps between your fingers.
During the partial phases of an eclipse, even the shadows cast by leaves on trees can act as natural pinhole projectors, displaying the crescent shape of the sun on the ground. This phenomenon occurs because the small spaces between the leaves allow light to pass through and project an image of the eclipsed sun below.
For those who want to create their own pinhole projector, follow these steps:
- Make a small hole in a piece of card.
- Stand with your back towards the sun.
- Hold the card above a smooth, light-colored surface.
- Adjust the distance between the card and the surface until you see a clear projection of the sun.
This method is recommended by NASA Eclipse Safety as it completely avoids the risk of looking at the sun directly.
