Very impressed my good man. Would it be possible to automate this process a bit and get some statistically sound measurements from doing it 100 times? Can we turn this into an online business? :D

Re: Making My Own Glasses
#82Misleading title. He tested his own eyesight and ordered glasses online. He didn't make his own glasses. Still an interesting read, just not what I expected from the title and lead.
Eh... he provided custom specifications to a manufacturer. Apple makes it's own SoCs for the iPhone, only Apple can't make semiconductors. They provide specifications to a manufacturer. Apple makes the iPhone, except it's Foxconn that manufacturers it. The APU in the Xbox One is made by Microsoft, but it's composed primarily of off the shelf designed CPU and GPU cores from AMD and manufactured by TSMC/GF/ .
The whole blog post was about measuring eyesight, not about what it takes to actually make glasses.
My natural expectation was that the author made his/her own lenses and fitted them into a frame. Or designed their own frame, ordered the parts and then assembled them into a frame. I was expecting a technical rundown about all the steps it took to do something like that.
The blog post is still a fun read, but the title is definitely misleading.
Re: Making My Own Glasses
#83Good story but I'm a touch disappointed as I came in expecting a story about making the lenses.

It's important to only do eye tests when you are tired, so you get lenses that help you when you need them.
Sorry, that's bollocks if not outright dangerous advice. You always need glasses... and having wrongly spec'd glasses will induce massive stress on your eyes and brain. Please consult with a medical professional.
But you do have to choose specifically _when_ you consult with that medical professional. Late in the afternoon after a day in front of the computer, when your eyes are tired? Or first thing in the morning when they're fresh?
Re: Making My Own Glasses
#85Title is a bit misleading and got my hopes of that this was about grinding down glass into perscription lenes. Interesting none the less.
Re: Making My Own Glasses
#86A similar incident happened with me too. Visited an optician, immediately followed by a doctor the same day. The measurements varied by 1 whole digit!
Re: Making My Own Glasses
#87> As a doctor I know some things about the human eye so I understand how to use those lenses. However, I have no clue about the magic ritual of the optician (“Do you see better with this lens?” - selects random lens and holds it in front of my eye). >Luckily, I didn’t have to. There's a specific reason why they do this and ask you to make a decision in an instant. It's called accommodation. Your eyes will quickly try…
Yes, I am a doctor. As far as I remember, I studied medicine and graduated. As other comments point out, medicine is a very specialized field nowadays and I didn't specialize in any field (I got into coding healthcare software instead) - in Germany you study all disciplines at University (min. 6 years) and then specialize during something comparable to US residency in a hospital. I understand the process of accommoda…
If I may, particularly as a doctor yourself, you should call the eye doctor "ophthalmologist", as you surely know if you use "part of the body + doctor" there might be issues should you report a visit by a "proctologist" ...
Re: Making My Own Glasses
#88Fascinating hacker story in an unexpected domain. Thank you! A side note about "getting your numbers"... The author remarks, "she’s not happy to share the measurements with me as she fears I’ll run off and get my glasses made online". This will obviously vary by jurisdiction but what the author describes may be illegal in some places. e.g. where I live, there is a law since 2010 requiring opticians and optometrists "…
Not sure about legality but here in the UK you will find opticians will give you your prescription, but often exclude the pupil distance measurement (I think) which a lot of the online stores require. I think you can ask for it, but they will only give it begrudgingly.
I recently (in US) asked for it, and was given a hand written sticky, begrudgingly after asking why you need it. But once asked again, no further objection.

There is a big difference between farsightedness and shortsightedness. Optometrists can use eye drops that prevent accommodation for farsighted patients, or they can detect the "plateau" in good vision and take that into consideration for the prescription. No need to wait until your eyes are no longer "fresh" unless you have a really bad optometrist.

Haha! Good point. I guess I thought "eye doctor" made for easier reading, assuming not everyone knows that ophthalmologist == eye doctor.
