This helps a lot. If I were able to go into a shop selling various strengths of diopter power this would be immediately apparent. That's the trouble with buying things on line.
THANK YOU very much for this! It can be SO confusing to figure out what to buy to enhance visual acuity. I have only peripheral vision. I am trying to find something to help me see/read with that limited visual area, not an easy task with so many choices and so little info. If I am understanding you correctly, the 3 di-opter actually gives you more work area and neither 3 0r 5 have a thing to do with magnification. I REALLY appreciate your information, it's very helpful indeed. Take good care of you and yours.
Thank you. One more important thing I'd like to know is about work area... In case of 5 diopters what's size of work area you can see without distortions from one view point?
I'm looking for recommendations video for clamp adjustable magnifying light for my home workbench. The lighting in the room is potato so I need a working light for soldering, upgrading my pc , modding consoles, etc.
Thank you so much for that explanation!!! Now I can use my diopter with knowledge instead of guessing where to position myself the lens and my work!!!!!!
It would also me good to mention that the word DIOPTER is not some mambo jumbo name that came out of someone's mind. Diopter, like most scientific, medical, etc words, came from the Greek word DIOPTRA (ΔΙΟΠΤΡΑ). The word OPT means eye. That why you have words like OPTICIAN, OPTOMETER, ETC. It was first used 300 year B.C. for observing the stars.
Trying to figure out if I should get a 3 or 5 dioplter to sew with. The work has to be about 12 inches from me face for me to reach the back so i'm thinking I would do better with the 5?
Thank you. I did not know that the lower the diopter, the better the working distance. I was thinking opposite. Glad I came here. Great Vid thanks so much. Off to buy a new jewelers head loupe armed w/ info.
Now I know no need to concentrate on the magnification. More important is the distance between the object and the lamp so makes you more comfortable to work with.
A dioptre (British spelling) or diopter (American spelling) is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in metres. (1 dioptre = 1 m−1.) It is thus a unit of reciprocal length.
Am I doing the math right? You said a diopter is a magnification of 25%. You then said that a 3 diopter is equal to 1.75. Well, if you multiply 3 time 25%, you come up with .75, not 1.75. What am I doing wrong here?
You have increased past ONE 25 percent times three which is .75 since 25% of one is .25. You have multiplied the .25 by three giving you .75 added to your (ONE). 1 x .25 x 3 = .75 __________________________ 1 x .25 = .25 .25 x 3 = .75 1 + .75 = 1.75

Excellent, this was exactly what I wanted to know. I feel very lucky to have found this video/explanation without too much searching. 10/22/2023
That was really useful. It's amazing how such simple explanations are hard to come across. Thank you

This explains my issue after buying an 8 diopter. Thanks.

I really appreciate you taking your time to explain this. I want to purchase one today.
Thank you! This is something all consumers should know.
Thank you.

I'm glad I found your video before purchasing a magnifying lamp. Thank you!
A very helpful and clear video. Thank you.

When you put one lens on top of another, do you add the diopter ratings of the two lenses or multiply them together?
Fresnel dioptre?
¡Gracias por la explicacion!! Thanks for your explanation!!
Thank you! Everything I wanted to know about the word Diopter but was afraid to ask.
fantastic video, perfectly explained
What does R - 2.00 -0.75 160.0 mean please? Short or distance
so owhat is a good one to remove a splinter from my finger
Thank you. I did not know that the lower the diopter, the better the working distance. I was thinking opposite. Glad I came here. Great Vid thanks so much. Off to buy a new jewelers head loupe armed w/ info.
Excellent!! Thank you so much Toby 🙏🏽🤙🏽🤙🏽
I have macular degeneration and double vision.Any info on these?
I just found a brand NIB 4 diopter 5" OC White diopter on Ebay for 100$, can't wait to have it! The cheap Amazon magnifiers are useless...
what about 14.75 diopter?
Excellent explanation really I got a very good idea about the diopter
Thank you! I learned something very interesting today👍
THANK YOU!! now I know what I will be looking for.
Concise and practical thanks much appreciated 😊

Anybody else notice his accent seems to float back and forth between British and American?

1 x .25 x 3 = .75
__________________________
1 x .25 = .25
.25 x 3 = .75
1 + .75 = 1.75
Thank you....very informative video .
Excellent explanation of Diopter.
I totally was looking for a photography diopter and the math behind them
Well explained...
very helpful
Yes very helpful. Thanks
Thanks!
Check kiya ja sakta hai nahin fight se
Nice vid but could've done with a practical demo.
im legally blind with degenerative optic nerve and have to hold stuff right in front of my face no matter how big it is practically
Can someone tell me why his accent went away when he said curvature? lol
