Contact lens technology has come a long way since its humble beginnings in the late 1800s. In 1888, German ophthalmologist Adolf Gaston Eugen Fick invented the first successful scleral contact lenses, which were made of blown glass. In 1961, Czech chemist Otto Wichterle made the world’s first hydrogel contact lenses. Fast forward to 2021, and augmented reality...

Have you ever thought about what it takes to be an astronaut? Or wondered whether you could become an astronaut, even though you don’t have perfect vision and you wear contact lenses?  With space exploration in the news, thanks to NASA, Elon Musk, and others we dive into this exciting area as it pertains...

The soft contact lenses available today are made of either hydrogel or silicone hydrogel. The question is: what’s the difference between these two contact lens materials? The history of hydrogel contact lenses In 1959, Czech chemists Otto Wichterle and Drahoslav Lím published a paper entitled “Hydrophilic Gels for Biological Use” in...

Always at the forefront of technological advancements, Google has applied for patents for a set of smart contact lenses. The contacts lenses, which go beyond the aesthetics of the wearable technology trend, have a medical purpose: they can help the blind “see”. The contacts, which would be embedded with a small camera and sensors, would assist the blind in...

Diabetes is a huge and growing problem - health professionals claim that one in every nineteen people on the planet is plagued by the disease.

Bionic eyes could help patients with retinal disease.
In February 2013, the U.S. Food and Drug Administration (FDA) approved the Argus II Retinal Prosthesis System, also referred to as the bionic eye. Developed by Dr. Patrick Degenaar and his team at Newcastle University, the fake eyes are intended to help sufferers of retinitis pigmentosa, a genetic condition that affects one out of every 3,500 people in the...

3D-printed eye cells could one day cure blindness.
The 21st century has seen the inception and growth in popularity of 3D printing. With well-known applications in architecture, manufacturing, and engineering, the technology is now increasingly being used in medicine. When combined with organic inks and thermoplastics, 3D printing technology has enabled the “bioprinting” of a range of human body parts, including 3D-printed eye cells. A group of scientists...

Braille contact lens technology is one of the latest innovations.
Researchers in Israel are working on a special kind of contact lens that they say will could enable the blind to see. The contact lens would use the eye’s tactile sensors to give blind people the ability to “feel” shapes with their eyes, much in the same way their fingers feel Braille. The bionic contact lens would have the...
