The Effects of Blue Light–Filtering Intraocular Lenses on the Protection and Function of the Visual System

Figures & data

Figure 1 Illustration of visual disturbances: halos and spokes.

Figure 2 Photostress recovery times in patients experiencing glare while driving (A) and contralateral comparison of photostress recovery times in patients (n=50) with AcrySof^® (Alcon Vision LLC, Fort Worth, TX) BLF IOL and non-BLF IOL. (B) Data from Panel B was derived from Hammond et al.⁴¹

Abbreviations: BLF, blue light–filtering; IOL, intraocular lens.

Figure 3 Macular pigment absorbance distribution. Macular pigment affects central but not peripheral glare.⁸

Figure 4 Effects of blue light filtration on chromatic contrast. Colored filters can create luminance edges (A) and enhance chromatic contrast (B).

Figure 5 Blue light filtration can enhance visibility under hazy conditions.
