Hi Chirag ,After going through your case I would like to tell you that your glass power is showing myopia with ,with the rule astigmatism
i.e your minus cylinder is in horizontal axis(180 degree).First of all let me tell you 0.25 DS or Cylinder is just an instrumental error or inter observer variability error i.e two optometrist can have such small amount of error.It doesn't cause much of change in your visual outcome.I believe you may be suffering from oblique astigmatism or irregular astigmatism as the images are not in shape with the present glass prescription.Your axis may not be correct hence there is skewing of images at certain distance and field.Optical glass or fiber glass doesn't cause much of difference unless it is very thick.So I would advise you to go to a good optometrist who can do a auto refraction
along with good retinoscopy
to find the correct axis.If required do a topography too to rule out early keratoconus
and irregular astigmatism. Check the size of frame and vault if you have changed.If you are working more on systems or computers check for dry eye
or computer vision syndrome
.If you are more than18 years then you can undergo LASIK.. So as for now don worry mush go to your optometrist or your ophthalmologist and discuss about it....TC .Keep a good health and safe eyes....DR Ajay Shankar Kar,Cornea
