Effects of blue light–filtering intraocular lenses on the macula, contrast sensitivity, and color vision after a long-term follow-up

After 5 years, there were no significant differences in color perception, scotopic contrast sensitivity, or photopic contrast sensitivity between the blue light-filtering (yellow-tinted) IOL and the IOL with a UV-light filter only (untinted). The potential advantage of the tinted IOL in providing protection to macular cells remains unclear.
