Hello Doctor, very Nice Video, Thank you so much, I got a doubt If we got spherical power - then eye ball size is increased ???? and if we get cylinder power then we get change in cornea shape ??? pls explain the anatomy of eye related to spherical and cylinder power problem, pls comment i need this information urgent, if u make video then its great because videos are not available, Thanks in Advance

[@lawrencewinter]

Hi all, thanks for uploading. I have an interesting question. The trial frames allow the optician to place cylindrical and spherical lenses as they wish. But, having the cylindrical and spherical lenses with some distance between them will surely have a different effect compared to having a single lens with both cylindrical and spherical power. So are the trial lenses "offset", meaning that you could not put them in the other order (i.e. spherical first, then the cylindrical)?

A lens can correct myopia and astigmatism at the same time. An example precription will be: -2,00 -1,50 x180 It means that the lens has 2 diopters of negative sphere aswell as 1,5 diopters of negative cyl. The “x180” just indicates what axis the astigmatism correction is orientated.

[@visaeryon]

Can the power change from spherical to cylindrical over time?. I have been using spherical glasses for 8yrs but recently I lost my glasses, when I checked with a new optometrist he prescribed me cylindrical glasses with 90° axis, but the glasses don't seem to work at all, everything beyond 5ft looks doubled, when I asked about it to the new optometrist he says wear them for a week it will become normal, 4days have past since but no improvement, to be honest my normal vision is worsening. I have no idea what to do now?, should i go back to spherical or cylinderical will be all right if i wore it for a week?
