I have the same distortion, only it's getting dimmer too (result of radiotherapy following a malignant melanoma in the eye). I have lots of glasses stashed in startegic places!
I get cheap prescription specs (any old prescription for the bad eye right now, until it settles down and I want a match for the remaining peripheral vision).
Obviously only to be used for those 'find the crack in the PCB' moments.
All the best ..

You can always wear two pairs. I wear two 1.5s when one isn't enough. And 1.5 + 3.25 = 4.75: worth a try.
I have one of those, and although the optics and lighting are good, it's not without its drawbacks. :-(
(1) The spring balancing doesn't actually work very well. It's usually a struggle to get the head assembly to stay put where I want it, and even more of a struggle to get it to stay "parked" in the fully-folded position when I've finished with it.
(2) The rectangular base sits rather loosely on the clamp assembly, using a tapered pin located in a socket and held there by gravity alone. The pin is rather too short for the sideways forces exerted on it. Over time, especially with protracted attempts to get the springs to work as they should, the pin works its way out of the socket and eventually the whole thing just falls off. It's bloody heavy, and, because of all the springs etc, hard to catch.
(3) The clamp is designed for a narrow but thick edge. Looking at the "G", the height is 65 mm, but the width (from edge of clamp to centre of screw) is only 15 mm. With the inevitable sloppiness of that long screw in its short thread, I find it impossible to get a good purchase on my
20 mm softwood window-sill. The forces are considerable and you really do need this lamp to be solidly fixed. Consider carefully what you're going to fix it to.Suffice it to say, although I own and have used the Clarke lamp for many years, I'm going to order one of the cheap CPC models suggested upthread, to see if it's any more usable.
Or how about one of these?
