Abstract Smart wearable ophthalmic devices such as contact lenses have gained widespread interest owing to their compactness, portability, and versatility emerged the most promising, non‐invasive, for treatment diagnosis of a variety ocular diseases. While congenital eye diseases color vision deficiency (CVD) are reported, they show limited spectral adjustment range unavailability blocking harmful light high‐energy blue (HEBL). In this study, silver nanoparticle (AgNP) based multifunctional that can correct various types CVDs filter out developed. AgNPs controllably assembled via short‐peptide‐induced diffusion‐limited aggregation then integrated into lenses. By varying sequence concentration peptides, extinction value nanoparticles be broadly tuned in 400–600 nm range. The thus wide tunability capable efficiently correcting multiple HEBL. found excellent biocompatibility with cell animal tests. conclusion, provide candidate correction CVD protection against HEBL, pave way personalized devices.
