Age and visual acuity information of subjects from all three groups each using different fixation monitor technique, i.e. Blindspot, Fixation point change, and Both (this technique consists of Blindspot and Fixation point change techniques).

Visual acuity is provided only for the left eye. Visual acuity was tested at the Nencki Institute of Experimental Biology of the Polish Academy of Sciences in Warsaw with the use of ETDRS charts (5 m for BCVA/UVA and 33 cm for CNVA/UNVA). Visual acuity results are expressed on Visus scale (also known as Snellen scale). Twelve subjects wore glasses for distant vision correction. One subject wore glasses for near vision correction. CNVA was measured for all subjects who wore any type of glasses.
