About this product

Model:  tv_dioptrx_2.5
Part Number:  DRX-0250

Astigmatism correcting lenses from Tele Vue. 

Your telescope's focuser compensates for your near or far-sightedness; the Tele Vue DIOPTRX™ compensates for your astigmatism.

Attaches and lock onto the top of over 20 long eye-relief Tele Vue eyepieces to achieve the sharpest possible full-field view.

Rotatable tuning to the best orientation. Engraved letters on the barrel helps to monitor orientation.

Premium quality fully multi-coated glass in an anodized aluminium cell with rubber eyeguard. 

Available in ¼ to 3½ diopter (¼ steps from ¼ to 2½ diopters, then ½ diopter steps to 3½-diopters). 

To choose the correct Dioptrx lens simply choose the lens that corresponds with the Cylinder reading on your eye prescription, ignoring the +/-. 


  • Sharp, high contrast views. 
  • Dioptrx can be rotated to precisely compensate for the astigmatic axis angle in real time (head angle and age can vary your eyesight astigmatic angle). 
  • Tele Vue Dioptrx likely has better optical coatings than eyeglasses, and certainly has better light transmission and anti-reflection reflection properties than uncoated eyeglasses. 
  • More likely to be cleaner than eyeglasses, which probably have scratches and smudges from constant use.

Dioptrx has made dramatic change
22 October 2019  | 

I have been struggling at wider views longer FL eyepieces in all my scopes,
I even started to think suddenly I had a faulty mirror on my 10" Dob, which I very much don't!
But no, it was faulty eyes, conversation with optician at my club confirmed I was seeing my own Astigmatism.
Simple solution was a Dioptrx, so duly bought one.

Well it has transformed things, fainter stars more obvious, very unequal doubles suddenly I can see.
This has literally transformed my observing and I will start to see more again.

So much more comfortable than eyeglasses at the eyepiece for me, which i kept not wearing, so saw Astigmatism.
10/10 item, Thanks TeleVue for such a great product and FLO for being that reliable supplier, as always they are.
