SOLAR ECLIPSE AND ITS EFFECT ON EYES
Partial Solar Eclipse as seen in Cairo
Special filters are necessary to see the solar eclipse without injuring our eyes
Solar eclipses can be witnessed at various levels and locations across the globe. Last subtotal solar eclipse observed in Egypt and most parts of Northern Africa, southern Europe, and extending west to parts of Northern and South America was on the afternoon of 3rd November 2013.
The question that always comes up about the solar eclipse is wether directly looking into the solar eclipse has any effects on eye’s health. Well, the sun’s rays normally contain a lot of ultraviolet (UV) rays, but as the human eye cannot look into the bright sunlight more than a few seconds, these rays usually do not cause any harm. In the case of the eclipse, we can look directly into the sun more easily, and our eyes can receive much heavier doses of direct UV rays, which can ultimately inflict serious damage to the retina in the back of our eyes. It is therefore mandatory, if we want to enjoy the sight of such a unique phenomenon like the eclipse, we must use specially designed filters to block these UV rays..
