Binocular Safety

Hi all

I'm not sure if this has been discussed before, if it has, then I apologise for repeating it, but I feel that it is a subject that needs to be reinforced for anyone coming into birdwatching.

As an amateur astronomer one of the first things that you are told when using binoculars or a telescope is never turn them towards the sun, instant blindness will be the result, this lesson is drummed in, there are warning labels on telescopes about the danger.

When it comes to birdwatching, no one is going to deliberately turn their binoculars towards the sun, however, when you are following a moving bird, then it is all too easy to wander into the sun's glare, remember, all it takes is a fraction of a second for blindness to occur. When I am out and the sun is shining, I am always aware as to the position of the sun, if a quarry is in the direction of the sun, if you cannot get into shade, then leave it alone. Even the rarest bird is not worth going blind for.

Always play it safe with the sun.

Paul

I think most people will inadvertently cross the sun with their binoculars at some point. I sure have. It is not pleasant but I'm not blind.

I thought the stare into the sun you will go blind was during a partial solar eclipse.

That's just because people are more tempted to stare then, than at other times.

Still wise advice, even if you won't go insta-blind it certainly can't be good for you, especially with high magnifications.

I read similar advice about digital cameras years ago: that you can burn-out pixels on the sensor if you accidentally point it at the sun too long. Not sure if that still holds true.

I don't think that many people would be stupid enough to stare at the sun to the point of blindness!

No chance here as I don't go out in sunlight as I have a pair of Zeiss Night owls!
