EYES ON THE SKY: SAFE SOLAR ECLIPSE VIEWING PRACTICES
Viewing a solar eclipse represents one of the most thrilling experiences one can have. The sight of the moon adroitly gliding over the shining sun mid-day, casting a shadow over the earth, is nothing short of breathtaking. However, dangers can lurk in-between the beauty if you do not adhere to the right precautions when viewing a solar eclipse. Below are some proven effective methods for safe solar eclipse viewing.
SOLAR ECLIPSE: BEAUTY AND DANGER
A solar eclipse happens when the moon moves between the earth and the sun, either partially or entirely covering the sun for a short while. This astronomical event is a sight to behold because of the compelling visuals it produces and the rare instances it occurs within a year.
However, as enchanting as the event may be, unsafe viewing of a solar eclipse can cause severe damage to the eyes. Looking at the sun directly without protection during a solar eclipse can lead to solar retinopathy, a condition that results in loss of vision due to the sun’s intense rays damaging the retina.
SAFE VIEWING PRACTICES
To avoid causing permanent damage to your eyes and enjoy viewing of the solar eclipse, here are few safe practices.
1. USE ECLIPSE VIEWING GLASSES
This is the most crucial safety measure you can take. Special-purpose solar filters or eclipse glasses should be used at all times when looking at the sun during a solar eclipse. These glasses are designed with an extremely dark filter that protects your eyes from harmful solar radiation. Regular sunglasses, even those with UV protection, are not enough to shield your eyes from the sun’s harmful rays.
2. ALTERNATIVES TO ECLIPSE VIEWING GLASSES
If you find it difficult to get eclipse glasses, you can observe the eclipse through other safe means like a pinhole projector. A pinhole projector is a device that allows light to pass through a small hole and projects an image on a background. This way, you can indirectly view the eclipse without direct exposure to the sun’s harmful rays.
3. OBSERVE SAFE USAGE OF ECLIPSE GLASSES
Just owning the eclipse glasses is not enough; you must know how to use them correctly. Before and after viewing the eclipse, don’t look at the sun while putting on or taking off the glasses. The safest practice is to look away from the sun while positioning your glasses, then turn your gaze towards the sun once they’re securely on.
4. DO NOT USE OPTICAL DEVICES WITHOUT A SOLAR FILTER
Do not use optical devices such as binoculars, cameras, or telescopes without a solar filter during an eclipse. These devices focus the sun’s rays directly into your eyes, increasing the likelihood of injury.
HOW TO GET YOUR EYES READY FOR THE ECLIPSE
Preparing for an eclipse involves more than grabbing the nearest pair of eclipse glasses. Acquaint yourself with the timing of the eclipse to enjoy the fullest experience. Check the local news and weather forecasts to ensure that the weather would be clear enough to experience this celestial event.
Prior to the day, ensure your glasses or solar viewers are not damaged. If they are scratched or damaged, discard them. Also, read and understand the instructions on the packaging. It is crucial that you don’t take any risks when your sight could be at stake.
