Polymer-based nanocomposites exhibit different optical virtues such as high refractive
index (RI), Abbe number (νd) and visible light transmittance (T %) above 90%. These
hybrid materials attract more interest in optoelectronic applications such in the
ophthalmic optics. The aim of this work is to study the impact of contact lenses doped with
aluminum nanoparticles on aberrated human eye. ZEMAX mainstream optical design
software was used for eye modeling based on Liou & Brennan eye model and then the
BHESP/PA/AL contact lens was applied. Ocular performance was evaluated by modulation
transfer function (MTF), spot diagram root mean square (RMS) and the geometric
encircled energy (EE) metrics. The used criteria show that the best visual performance is
obtained when BHESP/PA/AL-CL is used (P < 0.0001) because it reduced the generated
monochromatic and polychromatic aberrations inside the eye. The required balance
between the refractive index and abbe number of the chosen polymer affect the
transparency, transmittance and refractive errors correction.
