Solar eclipses are universal in appeal. There is something about the rarity of a total eclipse of the sun which captures the imagination of people of all ages and from all walks of life. However, it’s important to use an approved solar eclipse viewer when you stare at the darkened sun. Here are some important features to look for when you shop for viewers.
Protection
A good viewer offers maximum protection for your eyes. Make sure any viewer you purchase blocks out or filters 100 percent of harmful ultraviolet light. UV light is known to damage the eyes, especially with long term exposure. However, the sun is also the source of another invisible threat, infrared light. A good viewer should also filter out 100 percent of infrared light from the sun. Because these hazardous are not visible to us, you may not even know your eyes are being damaged.
Comfort
Comfort is very important besides eye protection. Look for a solar eclipse viewer which blocks at least 99 percent of intense light from the sun. This makes it comfortable to watch and increases the fun and enjoyment. Look for viewers with an optical density of at least 5.
Glasses
Solar eclipse viewer glasses are very simple and easy to use. You only need to put them on your head and your hands are free to do other things while viewing the eclipse. Many eclipse glasses are made just like the famous 3D glasses people use for viewing 3D movies and events. They are very inexpensive and offer excellent protection from harmful sun rays.
Hand Held Viewers
Not everyone wishes to view eclipses with glasses and you can also order inexpensive hand held viewers. The hand held solar eclipse viewer is very practical and only three inches by five inches in size. You can stack them easily and they fit into most pockets.
Cost
How much should a good viewer cost? This depends on what kind of materials you choose. You can find some excellent viewers made from heavy duty materials and costs can vary from about $3.00 to less than $1.00 per pair. Of course, businesses and organizations can save a great deal of money by placing large orders. In addition, the best solar eclipse viewer suppliers offer customized printing services with their glasses and hand held viewers. In addition, when you place a large order of 1000 viewers or more, you can lower your costs to below fifty cents per unit.
