You can wear sunglasses to protect the eyes. In fact, most of people are aware that exposure eyes to sunlight can damage the retina. However, there are really small group of people aware that solar eclipse is still dangerous enough to eyes such as retina damages. In fact, even in solar eclipse, there are invisible sunlight around us. So, you still need sunglasses to filter the sunlight during solar eclipse. -

Yea, it is bad for the eyes to look at a solar eclipse without taking any measure to protect the eyes. Viewing an eclipse or even the sun can lead to a condition called solar retinopathy. In other words, the retina is damaged by the sun. As the ultraviolet light is high energy, when it strikes the retina, dangerous particles named free radicals which damage the photoreceptors in the back of the eye produce. But the photoreceptors are the structures that allow the eye to detect light, hence the decrease of vision occurs, sometimes it causes blindness in some serious case. Therefore, to view a solar eclipse, you should take necessary precautions. The safest and most inexpensive method is by projection. Or you can wear specialized sunglasses to view a solar eclipse. You cannot be too careful to observe a solar eclipse. -

When there is solar edipse, the sun is covered all or partiality the moon, some people may think it's safe to look at the sun directly which can be a big mistake. In fact, even the light from a part of sun can be harmful to eyes which can cause permanent damage and even blindness, because our retina doesn't have nerves to adjust itself.   The ways or tools to observe solar eclipse recommended: 1. specialized detectoscope; 2. Small hole imaging method( observe the projection image through: 1). the holes on paper. 2). the Intermittent formed by crossing your hands. ) 3. Telescope projection method 4. sunglasses The ways or tools to observe not recommended: 1. floppy magnetic core 2. exposures film 3.X-ray film Besides, you need to have a break after observing it for 2 to3 minutes. Hope that can help you. -
