Diopter

A dioptre (British spelling) or diopter (American spelling), symbol dpt, is a unit of measurement with dimension of reciprocal length, equivalent to one reciprocal metre, 1 dpt = 1 m−1. It is normally used to express the optical power of a lens or curved mirror, which is a physical quantity equal to the reciprocal of the focal length, expressed in metres. For example, a 3-dioptre lens brings parallel rays of light to focus at 1⁄3 metre. A flat window has an optical power of zero dioptres, as it does not cause light to converge or diverge. Dioptres are also sometimes used for other reciprocals of distance, particularly radii of curvature and the vergence of optical beams. The main benefit of using optical power rather than focal length is that the thin lens fo… more »

I used to dream about white picket fences
And down that path, surely I strode
Never feeling myself move
Eyes fixed on the road
I used to be in a place where
The world was mostly on me
A singular constitution
A lonely place to be

Just give me a road to run on
Just show me a path that's clear
With the wind, I will move ahead
No looking back
Never fear

I used to dream about far away places
And deep down I knew
The wrong path was taken
Then I met you
Gave love and direction
Found a strength in me
Set us in motion
Now we're something to see

Just give us a road to run on
Just show us a path that's clear
With the wind we will move ahead
No looking back
Never fear

Just give us a road to run on
Just show us a path that's clear
With the wind we will move ahead
No looking back
Never fear

Just give us a road to run on
Show us a path that's clear
With the wind we will move ahead
No looking back
Never fear

No looking back
Never fear

No looking back
No looking back
Never fear
Never fear
