I'm 30 yrs old; I had a recent eye exam and dilation ---> no problems
were found. I went to the optometrist because I'm having a slight
"contrast problem" with my right eye - very slight (but enough to cause
headaches). Basically it's a small sense of 'brightness' in my right
eye while using the computer, and the same 'slight' brightness looking
around (at any distance) while outside in the daytime. My sphere is
-4.00, cylinder -1.00.

Interestingly, I just now found a pair of old reading glasses (+1.50)
and while wearing BOTH pairs of glasses at the same time, the
brightness (while staring at the computer screen) is completely GONE.
As soon as I remove the reading glasses, it returns instantly. I
believe this might be an important discovery but I don't know enough to
suggest a course of action to my optometrist. This is why I'm asking
for opinions here :)

I'm assuming that the reading glasses are decreasing the overall
sphere, and that this is making my eye feel better. But if he decreases
the sphere to make it easier for me to stare at the computer it would
make it more difficult to see far away (-4.00 is already a little weak
I think).

My question is, if he decreases the sphere to correct my computer
problem, will an equal increase in cylinder (from -1.00 to -1.50) allow
me to continue seeing well enough at far distances?
