what is the diameter of the lenses?

The head piece is approximately 5/16 of an inch in diameter. If you have a 1/2 inch to work in it works well but the barrel at the head is approximately 2 inches long so not ideal for tight curves. Works well though.

The inside clear lens is 3" in diameter and the outer ring outside diameter is 3 1/2"

About six inches. Probably a little less. One of the huge benefits of this wonderful little lens!

About 6 1/2" wide (across the front) and also 6 1/2" from the front to the end of the ear rest. The front lens is about 1 1/2" high. (Easily large enough to wear over my glasses.)

1 + 15/16" (inches) at tallest measurement. As photo shows, the 2 lenses gradually slope inward, diminishing shorter as they approach nose area. I agree re 2 1/2 inches at widest part, + a bit less than 1/16" at widest point measured at a left toward right sloping down angle. They're light, firmly fit; easy to wash clean with cool tap water; lightly towel-blot to dry. Cheers!

They are (from head on) 2.4mm X 3.3mm, including the larger part. The lens part that pops out is still 1.8 mm in diameter. This site has the dimensions. http://ledz.com/?p=leds.1.8mmFWIW, they are very bright regardless of package.

I believe they are the 29-32mm. I've used some others that have been identified as 32mm, and these were just about the same size.

so sorry, wish i could tell, i gave them to a friend as a gift and am not sure of the diameter.

From eyepiece to end of lens is 7 and 1/4 inches. Width at widest spot ( by end of lens) is 7 and 3/4 inchesBarrel of lens diameter is 2 and 5/8 inches. Great binoculars, very clear view.

The outer diameter of the eyepiece is 1.25" or 1.25 x 25mm = 31 mm approximately. Another issue to keep in mind is that this eyepiece is not a lightweight, and therefore not suited best for really light scopes.

the two lenses are fairly tight. I'd have to estimate at 15 feet the wide might be around 3 or four feet in diameter- but it is just that- a circle, with crisp edges. think of a stage spot light. These are the best with a mirror ball, actually they're spectacular!

The largest part of the lens is just under 2". If you had a two inch hole they would have clearance.

Bernard, these are approx 13mm. They are very slightly smaller than the originals on my eye glasses but I haven't noticed that difference since first installing them. I'm very happy with the product. I hope this helps you.

The diameter is 1.25". The focal lengths are 20mm and 10mm, but those are used to determine the magnification, while the diameter is the width of the eyepiece barrel. The 1.25" is considered standard size, although you can buy 2" eyepieces for much more money. Most telescopes accept 1.25, but the pricier ones accept both 1.25 and 2 inch diameter eyepieces.

I physically measured mine using a digital caliper, it can only hold lenses with diameter 65mm safely.

52mm diameter. And yes, it fits in with the standard front thread of lenses with 52mm.

They are the same size as the original half jacket lenses. My lenses fit exactly the same as the factory Oakleys. Hope that helps.
