Making My Own Glasses

> Optician: “Now with this lens, do you see better or worse?”

> O: “Honestly, I have no clue. Maybe. Maybe not? The letters look similar but different.”

[edit] Reprahsing to make it clearer:

will it be possible in the future to measure objectively?

This is clearly a case where the sole act of him sharpening his own perception of what glases do resulted in him getting better glases.

I work freelance as a colorist and re-recording mixer – both are professions which are highly based on perception. And it is certainly true: if you try to really go into the details of something, be it color, sound or anything else, it already helps a lot if you sharpen your senses to these things. I always say: you don't pay me for beeing able to use some software, you pay me for having developed my senses over years in a way that others didn't.

I know, I though it might a very expensive but precise way to measure that with time or new tech could become afrodable.

Since vision happens mostly in the brain, simply selecting a lens which focusing light at a certain point in your eye is not the only thing to optimize for. You also have to optimize for the processor behind the sensor which, at least until more advanced vision models are made, is going to be purely subjective.

> 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 and accommodate and find focus if they're allowed to stare too long. This could explain the reason he got such different results from the exams. He was trying too hard. Just follow directions.

Edit:

> One more thing. Do you remember the process in which an optician makes you wear a new pair of glasses and stares at you with this optician-look, takes the pair of glasses away from you again, goes to the back office and starts bending parts of it in a seemingly random manner, comes back, hands you the pair of glasses which now suddenly fit perfectly?

> Yeah, I attempted to do that with my new pair of glasses and noticed that I suck at it. I would bend it to look similar like the glasses from the optician only to realize that the back of my ears were hurting after a few hours of wear.

Is he really a Doctor??? He doesn't know there's a Mastoid bone there that the "bending" (aka: Adjusting) the optician is doing is to AVOID putting pressure on that bone!?
