Solar eclipse safety glasses available at Library

Thursday, August 10 2017 8:47 AM

A total solar eclipse of the sun will take place on Aug. 21. Those interested in viewing the eclipse should do so safely.

A solar eclipse occurs when the moon lines up between the earth and the sun, and the moon blocks the sun’s light from reaching earth. The eclipse, which is the first total eclipse in the lower 48 states since 1979, will last two hours and 38 minutes. Although Texas will not see a total eclipse of the sun, we should be able to view a partial solar eclipse (depending on weather). In the DFW area the eclipse will start at 11:40 a.m., reach its maximum coverage at 1:09 p.m., and end at 2:39 p.m. The moon will cover about 75 percent of the sun at the maximum coverage time.

In order to view the eclipse NASA has issued a safety warning to be aware of knockoff viewing glasses. Glasses that are safe for directly viewing the sun must meet the International Organization for Standardization’s standard, and will indicate they are ISO 12312-2 compliant.

The Colleyville Library is out of free glasses.

Looking at the sun without adequate protection, such as using regular sunglasses can cause serious vision problems.
