“…Contact lenses are generally manufactured via spin-casting, molding, and lathe machining process. − Spin-casting and molding are simple processes, where molds are required, and the anterior and posterior surfaces of the contact lens are formed in one step. In the molding process, the molds exhibit two surfaces that define the anterior and posterior surfaces; whereas in the spin-casting method, the anterior surface comes from the mold surface, and the posterior surface is generated by spinning the liquid monomer resin.…”

Although the manufacturing processes of contact lenses are well established, the use of additive manufacturing for their fabrication opens many new possibilities to explore. The current study demonstrates the fabrication of personalized smart contract lenses utilizing additive manufacturing. The study includes 3-dimensional (3D) modeling of contact lenses with the assistance of a computer aided designing tool based on standard commercial contact lens dimension, followed by the selection of the suitable materials and 3D printing of contact lenses. The 3D printing parameters were optimized to achieve the desired lens geometries, and a post processing treatment was performed to achieve a smooth surface finish. The study also presents functionalized contact lenses with built-in sensing abilities by utilizing microchannels at the contact lens edges. Tinted contact lenses were printed and nanopatterns were textured onto the contact lens surfaces through holographic laser ablation. 3D printed contact lenses have advantages over conventional contact lenses, offering customized ophthalmic devices and the capability to integrate with optical sensors for diagnostics.

“…[8] When it comes to fabricating contact lenses, traditional manufacturing processes have always been used. [22][23][24][25] These processes include spin casting and molding, as they provide simplicity and cost efficiency, but they require post-processing because of an issue related to adherence. [24,26] Additive manufacturing is known to be used in the biomedical field, owing to its relatively high accuracy, low machine cost, and suitability for rapid prototyping/manufacturing.…”

Gold nanoparticles (GNPs) are useful materials that may be used in a variety of applications such as color blindness management, drug delivery, and bacteria reduction. When incorporated with optical lenses, GNPs cause an absorption dip in the transmission spectra of the lenses. Out of the aforementioned medical applications, color blindness management is the most benefited from such spectra absorption as it could potentially block problematic wavelengths that patients suffer from and hence manage their color blindness. Where color vision deficiency (CVD), also known as color blindness, is a congenital ocular disorder that has no current cure, and patients suffering from it rely on wearable aids that enhance their color perception by filtering out the certain wavelengths. Herein, customized gold nanocomposite contact lenses are fabricated via additive manufacturing to filter selective transmission wavelengths in the range of 540 nm and 560 nm. To allow selective filtering, seeded‐mediated synthesis of GNPs through nine growth steps is utilized to vary the GNPs’ size and plasmonic filtering properties. Thereafter, three contact lenses are fabricated with different GNPs concentrations and particle sizes. The results of the study indicated that the fabricated lenses could block certain wavelengths selectively while acquiring properties similar to commercially available eyewear.This article is protected by copyright.
