Don't look directly at eclipse

​Optometrists in Devon are advising the public not to look directly at the sun during this Friday’s solar eclipse.
 
The partial eclipse will take place on 20 March 2015, from about 9.25am across South Devon and Torbay.
 
Devon Local Optical Committee and the Optometry group at the School of Health Professions at Plymouth University say the public should not look directly at the sun with the naked eye, even if dark filters such as sunglasses or photographic negatives are used, nor through optical equipment such as cameras, binoculars or telescopes.
 
There is no safe system to directly view an eclipse. Viewing the sun in such ways could lead to retinal burns, which can cause significant and sometimes permanent loss of sight. Particular care should be taken with children.
 
However, people can use a pinhole projection method. This involves putting a hole in a piece of cardboard, and holding the cardboard up – with your back to the sun – so that an image of the sun is projected onto another piece of paper or card. This works well using a cardboard box, and will allow you to see the progress of the eclipse without damaging your eyes
 
Alternatively, use glasses with specially designed solar filters (bearing the appropriate CE mark) if you have to view the eclipse directly.
