Since contact lenses directly contact the cornea, the surface roughness of the lens may cause various side effects. In addition, gold nanoparticles can realize a variety of colors and characteristics depending on their shape and size. In this study, the surface roughness of tinted lenses containing gold nanoparticles of various sizes was analyzed using atomic force microscopy (AFM) at aspect ratio(surface to volume ratio) ranging from 1:1 to 1:10. The characteristics of the lenses were then confirmed. As a result, tinted lenses with different colors depending on the size of the gold nanoparticles were manufactured. The surface roughness of the lens decreased with increasing size of the gold nanoparticles. However, at aspect ratio of 1:10, increase in surface roughness was observed. In addition, it was confirmed that the wettability and antibacterial properties of the lens had the same effect according to the average surface roughness value. Therefore, it was confirmed that the addition of gold nanoparticles reduced the surface roughness of the lens, which had a great effect on properties such as wettability and antimicrobial properties of the lens. The produced copolymer controls the surface roughness of the lens, and thus it is judged that it can be used as a material for various ophthalmology applications.
由于隐形眼镜直接与角膜接触，镜片的表面粗糙度可能会导致各种副作用。此外，金纳米颗粒根据其形状和大小可以呈现出多种颜色和特性。在本研究中，使用原子力显微镜（AFM）在纵横比（表面积与体积比）从1:1到1:10的范围内分析了含有不同尺寸金纳米颗粒的有色镜片的表面粗糙度。然后确认了镜片的特性。结果，制造出了根据金纳米颗粒大小呈现不同颜色的有色镜片。镜片的表面粗糙度随着金纳米颗粒尺寸的增加而降低。然而，在纵横比为1:10时，观察到表面粗糙度增加。此外，根据平均表面粗糙度值证实镜片的润湿性和抗菌性能具有相同的效果。因此，证实添加金纳米颗粒降低了镜片的表面粗糙度，这对镜片的润湿性和抗菌性能等特性有很大影响。所制备的共聚物控制了镜片的表面粗糙度，因此判断它可作为各种眼科应用的材料。
