Single VS. Multiple Pinhole – Does It Make A Difference?

Linda McKenzie, DipAppSc(Linc), DOBA

The visual acuity of 29 subjects was tested using a single pinhole, a multiple pinhole and the best corrected visual acuity. Statistical analysis showed no significant difference in the visual acuity achieved using a single or multiple pinhole. It was also shown that a significant difference exists between the visual acuity obtained by pinhole and the best corrected visual acuity.
