My normal prescription is: OD -2.00 SPH; -2.00 CYL 180° and OS -2.75 SPH; -2.00 CYL 180°.
Lately, I have acquired a new pair of lenses because I wanted to try completely removing CYL by adding a spherical equivalent. So this morning I have begun wearing them, the prescription is: OD -3.00 SPH and OS -3.75 SPH; no CYL at all. Basically, I have subtracted a -1.00 as a SPH equivalent for -2.00 CYL.
The result so far is… interesting I’d say. Especially the Snellen test, which is the first thing I have done. I have managed to read the 30 ft line, which means a score of 20/30 (?). With the normal prescription, I have read 20/20 easily.
So since the Snellen result was not really bad at all, I decided to stick with this new pair and see what happens. The first couple hours I’ve been feeling very weird and dizzy. But I am enduring it, and now it seems to be much better after these 3/4 hours of wearing them.
Another interesting phenomenon is that I can see clearly when looking straight ahead, but peripheral vision is much blurrier. I think it is normal, but honestly I lack the technical knowledge so I quite can’t put a finger on the real cause of this phenomenon.
In broad daylight, with some active focus, I can see clearly, and if I am looking straight in the center of the glasses I feel like my vision is even more powerful than the previous normalized I was using. It looks like a real life sharpness effect. Unfortunately, as soon as my vision is not centered anymore, it becomes much blurrier.
Last thing I noticed is that everything looks more vertical than before. I mean, like more vertically stretched. And this is another weird phenomenon that I can’t technically explain.
Since after a couple hours the dizziness has eased out, I have decided to continue this experiment and see (heh) how it goes for another week. If it gives me problems, like not seeing properly when driving, I will return to the previous prescription.
So, did anybody have success in reducing high CYL values? If so, how?
