‘Hair Glasses’: Eyeglasses made of human hair

Made from hair and bioresin, the resulting frames are 100 percent biodegradable.

Human hair has been turned into sustainalbe eyewear by two Royal College of Art students, Azusa Murakami and Alexander Groves.  Petroleum-based plastic or energy-intensive wire frames are a necessary evil for those who are not blessed with 20/20 vision.  “Hair glasses,” however, tap into a readily available and renewable resource: the millions of pounds of hair cuttings that salons across the United Kingdom throw away each year.

Scientists have developed an eye implant that allowed three blind patients to see shapes and objects within days of treatment in a trial and say the device could become routine for some kinds of blindness in five years.

It has been known for decades that some birds are able to sense the Earth’s magnetic field and set their direction as if following a compass heading, which is an extremely useful ability for birds migrating long distances. The ability is believed to be linked to the availability of light and it is thought that specialized molecules in the birds’ retinas allow them to literally see the magnetic fields, which appear as patterns of light and shade superimposed over the regular image from light. Now a new study shows that the internal compass also depends on the birds having clear vision in their right eyes.
