Are sunglasses actually danger goggles?

[bonesX]

I mean - they do reduce the amount of information entering your eyes after all

We'll surely get the argument of quality items do not reduce anything, but how many buy cheapo sets which do just darken everything?

A neutral density filter does not reduce the amount of information entering your eyes.

If you need a metaphor, if you take a load of numbers and halve them all with enough precision, you still have as much information as you had before.



Polarising sunglasses reduce the amount of raw information entering your eyes, but it's usually information the eye isn't capable of understanding anyway.

[Snowboy]

It depends on how sunny it is (or isn') and the design of the sunglasses.

In general though, I think they aren't a problem.

[anonymous-user]

No

[Engineer1]

Provided you can still see through them and they aren't some daft tint colour they are fine.

I never drive wearing sunglasses. It feels like I'm in the box. Doesn't feel right.

As the risk of pointing out the obvious, you are in a box.

With the roof down, driving into the sun, I'd say sunglasses are a must - at least I can see with them on as opposed to guessing where the next car is...

Wear them a lot for driving, not only in summer but low sun and spray as well, when I wear them it's because my vision is being impaired in some way so I need to darken down the amount of light coming at me. Works well for brake lights ahead of you driving into the sun

Well the DO reduce glare, especially on a wet road, but they also DO reduce amounts of visual input

Much that 'unintellible' information is 'noise' in the form of reflected glare which one can very well do without. I find polarising glasses very useful in wet/sunny conditions. Can't always read LCD displays though.

Just bought some Oakley Crosshair Titanium Polarized..they are terrific driving roof down in the sunshine, so light and comfortable too..definitely better than my Polarized Raybans. I wouldnt leave home without them now

I'd rather have the information reduced through sunglasses rather than squinting or being blinded :-)

Unless you are going to paralise your iris I think you'll find you eye already does a good job of reducing the amount of light that goes in. Plus squinting, which is what people too poor to buy even cheapo sunglasses have to do.

Sorry, I meant "danger iris".

[conkerman]

You need some peril sensitive sunglasses.

[CrutyRammers]

Try heading down the M6 on a january morning with the sun just skiming the top of the wet road, and a windscreen covered in spray. It's sunglasses or arc-eye.

[cianha]

Which reminds me, it's time to call the opticians for my eye test.

[10 Pence Short]

I have big pupils and my eyes are very sensitive to light. My work requires me to drive regularly and over long distances. Without sunglasses I would generally struggle.

I would imagine they only become 'dangerous' if you wear them at inappropriate times.

That's why they ouoght to be used in situations of information overload.

What a beautiful morning! Think I'll be wearing mine today :-)
