Two NASA official eclipse viewing locations in Hampton Roads

Looking at the sun directly, even just the sliver of sun visible before the total eclipse, can cause permanent eye damage.

This time, the path of total eclipse will be about 70 miles wide and begins in OR on the west coast and travels to SC on the east coast, the National Aeronautics and Space Administration (NASA) reports on its eclipse website, eclipse2017.nasa.gov.

Made from an extremely opaque black polymer film containing fine carbon powder, true solar-safe lenses are created to screen out 250,000 times more visible light than would otherwise reach the naked eye, said B. Ralph Chou, a Canadian optometrist who led development of global standards for solar optics. Normal sunglasses don't provide enough protection. Safety glasses for viewing will be on hand for free while supplies last.

In Rhode Island, we'll only get to see a partial eclipse.

Always supervise children using solar filters.

The American Astronomical Society has listed manufacturers of eclipse glasses on their site, which are verified to be compliant with the ISO 12312-2 worldwide safety standard. Optometrists want to reinforce that the only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters or other ISO-certified filters, such as "eclipse glasses" or handheld solar viewers. The filter should always go on the front of the device.
