I recently got a new pair of glasses. The shop prescribed me with an addition of 0.25 degrees as compared to my previous pair. However, I felt giddy whenever I put them on. Is this due to the curvature of the lenses or non-matching degree?

Whenever I change my glesses, it takes me several days to get adjusted. Some take longer. As you so rightly pointed out, it could be due to the curvature of the lenses. The difference of 0.25 is really not significant. However, if after a reasonable duration, you still have difficulty with the new glasses, you should bring them back to the shop and explain the problem to your optician. If there is a big "jump" from your old glasses, then the degree can be reduced a bit to make it more comfortable for you, but then the vision may be blurred.
