Visual Performance of Defocus Incorporated Multiple Segments With Triple Enhanced Design Spectacle Lenses Versus DIMS and Single Vision Lenses.

Most visual functions showed no differences before and after lens wear.

Central high- and low-contrast distance visual acuity and central high-contrast near visual acuity under room and dim lighting were unaffected by defocus incorporated multiple segment and defocus incorporated multiple segment TED spectacle lenses compared to single-vision lenses (all P > 0.05).

However, these reductions are unlikely to represent a clinically meaningful impairment in visual function.

Most children adapted and accepted the defocus incorporated multiple segment TED spectacle lenses well.
