<\/p>\nImagine seeing the world in muted shades \u2014 gray sky, gray grass. Some people with color blindness see everything this way, though most can\u2019t see specific colors. Tinted glasses can help, but they can\u2019t be used to correct blurry vision. And dyed contact lenses currently in development for the condition are potentially harmful and unstable.<\/p>\n
<\/p>\n
Now, at Abu Dhabi\u2019s Khalifa University, researchers report infusing contact lenses with gold nanoparticles to create a safer way to see colors.<\/p>\n
In colour blindness, the most common kind is protanopia and deuteranopia \u2014 difficulty separating red and green colours.<\/p>\n
Usually, for remedying this, people wear special glasses which have a tinted glass that enables them to see the specific colour that they can\u2019t otherwise see<\/span>\u00a0but not only are these lenses really bulky, but they cannot be used for correcting other vision problems simultaneously.<\/p>\n Moreover, researchers in the past have also worked on developing lenses to help bridge the gap between the two, however, the dye that was used to create the special tint in the lenses were not the safest, nor were the lenses as durable.<\/p>\n However, now, researchers from Abu Dhabi\u2019s Khalifa University have developed a novel lens infused with particles of gold. These lenses are non-toxic and this method of infusing gold in glass has been going on for centuries, in order to create cranberry glass as they scatter light in a different manner.<\/p>\n For developing the lens, the researchers infused gold nanoparticles in a hydrogel. This resulted in the production of a red-tinted gel that filters wavelengths of light between 520 and 580 nanometres \u2014 the section of the spectrum where red and green wavelengths overlap.<\/p>\n As per the researchers, the most effective contact lenses were made with 40-nanometre wide gold particles that neither got stuck together nor passed through more light than necessary<\/span>.<\/p>\n Researchers have successfully completed their initial study and now they\u2019re conducting clinical trials to understand how comfortable is the experience wearing these lenses. They are yet to be assessed in clinical trials.<\/p>\n","protected":false},"excerpt":{"rendered":" Imagine seeing the world in muted shades \u2014 gray sky, gray grass.
