Can anyone tell me why the right eye has a word for the sf value? Could this mean 0.00 And what does this ADD mean in the left eye data? ADD number is not asked when filling in data on the glasses store page.

One image is of the prescription and the other is of the eyeglass shop data cells.

It would be necessary to order distant vision glasses.

    Retseptis on nii kaugele (procul) kui lähedale (prope) nägemise andmed. ADD tähendab seda, et kui palju need omavahel erinevad. St. kui vasaku silma kaugele nägemise tugevus on -0,25 ja ADD on 1,75 siis lähedale nägemise tugevuseks on +1,5. Samamoodi vasakuga ehk jah, see tekst paistab tähendama nulli kuna lähedale nägemise tugevus on sama, mis ADD.
