Though solar eclipse may be a spectacular sight to view, it is highly harmful to your eyes. On seeing the eclipse with the naked eyes, chances are that one might go blind. Let us learn how?
The solar radiations emerging from the eclipse are extremely powerful and can easily cause a damage to the photo-receptors, which are cells present in the retina. This may cause permanent damage to one's eyesight.
Also, the UV radiations from the sun can be the reason of permanent damage to the outer structure of the eye and the intensity of the sun's brightness can easily affect the focal point.
I am sure most of you would be excited about the upcoiming solar eclipse. The eclipse will be visible in the United States and other countries, but it will not be visible in India. However, check here for few tips to protect the eyes during a solar eclipse. Have a look!
Never allow the sun rays to fall directly on your eyes, even for a short span of time. If after watching the eclipse you notice some discomfort in your eyes, like loss of central vision, not able to view colours, etc., you must immediately seek medical help.
1. Use Special Glasses
A special type of glasses, which meets the standards set by the ISO (International Standards Organization), can be a way of pinrotecting the eyes during the eclipse. Let us see how?
These pair of glasses make sure to block the UV rays, infrared and intense visible light emerging from the sun, thus doing a lot of good to the eyes. But care should be taken that the lenses of these glasses are
- Not scratched
- Not wrinkled
- Not too old (that is the glasses should not be more than 3 years old)
2. Take Care As You Remove the Glasses
After the eclipse, care should be taken to remove the specialized glasses while looking away from the sun. Never show the naked eye to the sun even for a few seconds.
3. Avoid Opitical Devices
Looking through camera, telescopes or any other optical device without proper filters should be completely avoided. The filters should be inserted properly at the front of these devices. Also, even while looking through a device with filters, the specialized glasses should be worn because there are chances that the intensity of the sun's rays can damage the device's filter, thus reaching your eyes and permanently damaging them.
4. Tips For Those Who Wear Spectacles
Supposing, if you always wear eyeglasses, then the solar glasses should be worn above it.
5. Seek Expert Advice
Seeking the advice of an expert is always essential to view the solar eclipse through any optical device. It is safe to view the eclipse under his/her guidance.
We all know that the solar eclipse occurs when the moon comes in between the sun and the earth. When there is a total eclipse that is when the sun is fully blocked by the moon, which can be viewed only in certain places from the earth, then the specialized sun glasses can be removed and the total eclipse can be viewed with the naked eyes.
This may only last for about one to two minutes. But when the sun starts peeking again that is when the partial eclipse starts occurring and in that care should be taken to put back the specialized glasses immediately to protect the eyes.
When you are viewing the eclipse outside the path of totality, then the specialized glasses should always be worn and never should be removed under any pretext.
Thus, by following the above-listed precautions, one can save our windows of the body, i.e., our eyes from getting damaged. Happy eclipse viewing!
