the optics are planar type?

Refractive wise is the same for planar vs distagon. However the way the lenses is cut will change the dispersion between the two. I would say it's planar. To be sure call tech Dept. At AmScope. Most good lenses from Japan & Germany are planar..obviously dispersion is the way the light is bent through lenses.

After you response or concern I got out my flashlight and yes you are correct there is 2 optics one pointed forward and one point back. The one point back is much more counter sunk inside and I didn't notice. Sorry

Hi Patti,They are crystal clear for long range viewing. The optics seem to be of exceptional quality for the price. They are, however, somewhat heavy but still easily handled. I'm on my second pair (the first broke while close focusing to the minimum) and this unit works very, very well. For the price it is an excellent buy if you can accept that they are mage in China.

The lens is clear glass and it is convex with just about a 1" rise at center. Gorgeous, show quality light that I have had on my fatboy for there years now. It is still perfect.

No is the short answer. Look for "macro" lenses or "magnifier" lenses or "microscope" apps or lenses

The picture I see is of the PermaFocus and these are what I received. I love them and can see great using my glasses.

I am not sure, but I will say they are fixed focus...there is no adjustment device. I have not been satisfied with these because of this.

No, but I believe there is a wide angle "mode" in the options. That said, it's really not the same thing as a wide angle lens.

8x fixed. Has eyepiece adjustment ( helpful if one user has glasses and the other doesn't). Also has a fine tune focus in addition to the main focus. We love these. We use these bird watching, kayaking and geocashing in a local state park.

They're plastic lenses. My husband absolutely loves them. They're perfect for fishing with the polarized lenses.

The lens I have are glass, and metal rings. They can turn for different effects.

Yes, they are. They are a combination of fiber optic (enhanced daylight visibility) and tritium (enhanced low light visibility). They are also brighter than my straight up tritium Meprolight sights that I have on several other of my guns.

The lenses are pretty good quality much like ones your find in regular sunglasses. They are not glass but a quality plastic.

The angle of view is equivalent to 30 mm in full frame 35mm camera terms. This would be considered moderately wide without offering much distortion.

Yes. They are lightweight, sharp of focus and easy to focus. The field of view is great for Alaskan wildlife.

The thing to keep in mind about these is that they are compact. So the eye pieces are set wider than the view lenses. Turn them around.
