There’s definitely no harm to them The issue is definitely a real one But I’m skeptical about how well they work and they also come with a lot of preconditions Furthermore they’re expensive, so I don’t push it too hard on my patients Hopefully something takes off for atropine…interesting topic though

Great post by on #Ireland’s electrical grid system and how bitcoin can play a role Great breakdown of a national electrical grid in general if anyone is interested #Ireland #Mining https://bitcoinnetwork.ie/energy-and-the-irish-electricity-grid-a-critical-look-towards-2030/

I only really understand your first question If you have eye strain your optometrist should consider doing cyclopentolate refraction or using prism. Your case history, cause of strain and has a recent change in your prescription prompted it all matter. Poor sleep and stress can cause it too. Prism corrects binocular vision. Remember you have 2 eyes but only see 1 image. There’s an entire network of muscles and nerves that work together to ensure you see one image. I have prism in my own lenses as I get some eyestrain sitting in my office all day. It’s not a big deal to get either and can make a major difference to your eyes Prism has other uses too btw

So regarding your last sentence, yes we are incentivised ofc but this is where I defend optometry Your eye development is mostly complete when you’re 8 years old and there is still some change until you’re 18 or so. So no matter what you do really, the trajectory of your vision is essentially set in stone Furthermore glasses aren’t like a drug or a crutch. They aren’t like a drug because the prescription itself does not reflect the quality of your vision. It reflects the quality of your vision vs what’s considered the standard but…—> fundamentally your quality of vision is what you can see with the sharpest prescription given to you —> some people could have a small prescription and terrible vision with or without glasses. For example a blind person’s best vision may be achieved with simply +1.00 but the issue is the health at the back of his eye to where the light is being bent —> Glasses are like a telescope, they bend light onto the part of your eye that is most sensitive to seeing, this is called your macula and it’s the quality of this that’s important. This is basically all determined genetically They aren’t like a crutch because there’s not a large amount of muscle needed to see. It’s mostly due to the shape and liquids of the eye and once you’re older than 40, the few muscles involved start to wane more and more anyways. You wouldn’t miscorrect a telescope to protect the magnification inside and likewise you should wear a fully corrected prescription. The potential protecting of muscle is negligible. Also some people think glasses make their vision worse but they may not have realised how bad it was before they got them. Even though this sounds salesy I fully stand by it and everything else The degradation of your near vision in your 40s is called presbyopia. Some people in their 40s don’t need any glasses because their eyes are NATURALLY a bit short sighted but only a bit so that they don’t need glasses for far away. There are a few other minor exceptions. But once everyone turns 60 and the presbyopia gets worse, basically everyone needs them

Anti reflective coating can help but it’s not necessary unless it’s +-3.00DS imo or if you struggle night driving. It’s important to know anti reflective coatings only reduce glare that originally comes from the lens, not glare fundamentally UV filters definitely reduce the onset of cataracts. People who use sunbeds have a much higher chance of developing pre mature cataracts due to UV exposure. However cataracts are an unserious condition and there may be negative consequences to not being exposed to UV…that I don’t know Other filters put on lenses are usually chosen by the patient - tints, polarising, transitions etc and nothing to worry about. I think blue light filters are a scam btw, too many leaps of thought and so so little real evidence. The best thing you can do for your mind and eyes is to just turn your phone off when it’s dark lol Honestly the simplest advice I can give you is wear glasses when you need them and don’t worry too much about anything else. I’d be very healthy conscious about my diet but don’t sweat the small stuff when it comes to your eyes. :)

Optometrist here 👋 🇮🇪 Frames are made of terrible quality nowadays and essentially have built in obsolescence to last 4 year years max, and most shops recommending changing frames every 2 years You use to be able to have frames made that would last your whole life and be constantly tailored but they no longer exist. You’d update the lenses when there was a significant change in the prescription The quality of lenses themselves have probably improved though. Varifocals are much better than bifocals for example
