Question: sir, I am a male of 35 years. I checked my eyes in 25 May 2013 and brought the glass accordingly(Glass prescription is attached here with this query). After one month I again checked my eyes and the power was the same so the doctor advised me to use the same glass and check it again after 6months. After 6 months the power was still same and the doctor told me to use the same glass. I was wearing the glass only when it was required not all the time. Even if I was not using glass since 1 year(Only distant letters were not readable otherwise I was able to read the nearby letters.). Today I again checked my eyes with the same glass and the doctor told me that there is not any change in my eyes so i may use the same glass. But when I saw today's eye prescription then I discovered a change in axis(previously axis was 85 in right and 100 in left eye but in today's prescription it is 80 in right and 90 in left eye). I afraid that my glass is made as the previous prescription (axis 85 in right eye and 100 in left eye) but if I use the same will it hamper my eye sight ??? Is my eye sight is going to be worsen if I use the same glass ??? Does the axis factor of glass matter for eye sight worsening ???(both of the eye prescriptions are attached with this query)
