For example, these materials could create contact lenses that correct visual acuity or sharpness. With further research and development, these lenses could provide a more natural and permanent solution for color blindness.įurthermore, this research opens the possibility of developing other nanocomposite materials to correct visual impairments. Additionally, the study only focused on individuals with mild to moderate CVD, and it remains to be seen if these contacts will be effective in individuals with severe CVD.ĭespite these limitations, gold nanocomposite contact lenses represent an exciting development in CVD correction. Therefore, further research with a larger sample size is necessary to ensure the effectiveness of gold contacts. Firstly, the study's sample size was relatively small. While the results of this study are promising, some limitations need to be addressed.

(a) transmission spectra of the nanocomposites (b) solutions before polymerization (scale: 10 mm). Furthermore, the contact lenses were well-tolerated and did not produce any adverse effects. The study showed that the gold contact lenses significantly improved color discrimination in individuals with mild to moderate CVD. The study recruited participants with CVD to wear gold contact lenses and complete various color-related tasks. These gold nanoparticles are engineered to selectively filter out specific wavelengths of light, which can help improve color differentiation and perception in individuals with color vision deficiency (CVD).Ī recent study was published in ACS Nano to investigate the efficacy of these gold nanocomposite contact lenses in treating CVD. Researchers have used these properties to create gold nanocomposite contact lenses that incorporate gold nanoparticles into the contact lens matrix. Gold is highly suitable for making contact lenses because it is biocompatible and has excellent optical properties. However, not all contacts are created equal regarding CVD treatment, and one novel type is gaining popularity over the others. Additionally, contact lenses can be worn during sports or other physical activities where glasses might be less practical. They provide a more natural viewing experience since they sit directly on the eye rather than in front of it. The filters can be customized to each individual's needs, allowing for a more personalized approach to correcting CVD.Ĭompared to tinted glasses, contact lenses are more comfortable and less obtrusive. These filters selectively block specific wavelengths of light, enhancing the ability of individuals with CVD to differentiate between colors. Recent technological advances have led to the use of contact lenses that incorporate special filters. Despite these limitations, tinted glasses remain a popular option for individuals with CVD who want to improve their color perception. Additionally, they can be inconvenient since they must be worn regularly to maintain effectiveness. While these lenses are effective, they are not a permanent solution. One well-known company that provides tinted glasses for CVD is Enchroma.
