[NSC] How much do you spend on SUNGLASSES ?

[dsr-burnley]

Won't be long and you'll no doubt be able to see people naked/deep faked real time with smart glasses, I saw Harvard students already made something with face recognition in them which can tell you strangers names, address, full bio just by looking at them. Rather scary really

Would be very useful for blind people. It doesn't even need to recognise strangers, just your own acquaintances. (Perhaps it's already being done?)

Question for opticians. Some of them say that we should wear sunglasses all day and every day to cut out ultraviolet light, because it will reduce the risk of having cataracts. But by how much does it reduce the chances, and is it worth it?

For one thing, cataracts seems to be pretty easy to put right. For another, it seems illogical to cut down the light reaching the retina now in hopes of avoiding a condition that will cut down the light reaching the retina.

But primarily, what are the numbers? I presume it's correct that a 75 year old who has worn sunglasses all his life has less chance of cataracts than one who never does. But what's the difference? What are the odds of each chap having cataracts? Sometimes these medical stats are made useless by lack of context, eg. the ones where they say eating such-and-such will double your risk of getting such-and-such disease; but when you look at the context, it means the chance goes from 1 in 2 million to 1 in 1 million and so can be ignored. What are the actual probabilities of getting cataracts in either case?

And if I do get cataracts, what are the chances of going blind?

I have just shelled out for a pair of prescription Oakley Frogskin Prizm polarised reflective sunglasses. First prescription sunglasses I have bought, normally go for transitions. Having had a couple of cataract operations I now find driving on low sun winter days too bright (not that we have had that many recently ) and possibly dangerous as coming off a roundabout I am almost blinded if the sun is low where I am looking. They are F’ing brilliant but at £420 they should be!

I went for genuine Oakley prescription lenses as the guy in Vision Express told me they were better quality than the Vision Express ones but more expensive of course. I may have been duped….

I only have one pair of eyes. I intend to look after them (also, my grandpa was an optician so I always used to get stern advice about things like watching TV in the dark and wearing sun protection etc). I swear by Oakleys and am quite happy to spend the money on them.

I do, however, also get that some people wear expensive sunglasses in the mistaken apprehension that it makes them look good.

Bought a transition prescription pair of these for over £300 a couple of years ago and then broke a lens on a run, they wanted £250 to provide a replacement lens so I got the super glue out instead!

I always do a two for 1 at Specsavers with the second pair being tinted, so zero cost for me.

But how do you know its not the second tinted pair they charged you for ?

Because I’m naive.

I forgot to take my clip-on sunglasses attachment to see the game at Fulham yesterday, so popped into TKMaxx in Putney to buy the cheapest ones they had - a natty almost punky pair of grey plastic framed UV400 shades that I placed over my specs. I only wish they'd been total blackout glasses.

I THINK that the UV protection is there largely irrespective of the darkness/shading, so yes, could be worn every day. The cost of modest/medium priced sunglasses is very small. But they should be properly certified/stamped etc. But there is no need to spend £250 purely for UV protection.

As you say, a question for any opticians on here...
