hye..i'm 3rd year student of optometry..i've found this web accidentally when im searching something regarding on my assignments.I've already wrote bout dis issue in my blog: http://adnexahani.blog.friendster.com/
I would like to emphasize here, there may be two conclusion if u feel better after wearing this spectacle. 1st, your accommodation is relax, so for short-sighted(myopic eye), the image is bring closer to your retina, so, thats why u have feeling clearer. 2ndly, with the pinhole spectacle yes, you may have the feeling of relaxation, because your eye is relax from accommodation and this feeling make you relief from eyestrain. But these feeling is only temporarily and only apply in certain condition (e.g you are overcorrect with current spectacle, you may not realize it because our eye easily adapt to it and yet causes big problem in the end.
Please check out my blog and for further detail explanation can email me..
People always claim their product good like all the slimming product...please dont be cheated, there is no establish way as far as optometrist concern method that can reduce spectacle power for short-sighted..but can to decrease the progression from become worsen.tq
