Research Subject

[da]

On Tuesday, I went for my 2nd of five visits to the optometrist as part of a research project on eyestrain. They gave me my new glasses, which initially made me a bit... alarmed... because the effect of turning my head was a bit like... that Hitchcock depth-of-field movie effect? You know the one I mean? Anyway, they did funky things to these glasses. I think it's a bit like progressive-lens bifocals, or maybe they're n-focals since it also does something odd side-to-side.

The research student tells me my eyes will figure out where to focus for close-up and distance work, which is slightly worrying, but the fact that I'm essentially adjusted to them this morning is at least promising.

I got my new ones last Friday. I like them so much I don't want to give them back - no headaches, no eyestrain at all since; the headaches were becoming a weekly occurrence and the eyestrain an every other day one.

My "regular" glasses are about 8 years old though, and are kinda scratched and yellowed (Linda used to smoke), and my prescription has changed slightly. I'm hoping that's not the only reason I've been suffering.

cool.

Did you see the same weird warping at the bottoms of the lenses?

Nope.

Three possible reasons:
1 - I just can't see it, and you might be able to.
2 - Lens shape is different and therefore so is the effect (or ditto for prescription).
3 - I'm in a control group that just gets regular lenses anyway.

interesting. yep, all of those seem possible. I'm leaning toward #2, the lenses are just different.

Glad you're hapy with them in any case. :)
