What causes discomfort among users of contact lenses

Melbourne, Nov 23 (IANS) If you are not comfortable wearing contact lenses, it could be due to degradation of the lipid layer in the eyes’ natural tear film, says a study.

Patients with discomfort showed degradation of the lipid layer after a few hours of wearing contact lenses, the researchers found.

The tear film is a three-layered “sandwich” of fluids that nourishes and protects the eyes.

The lipid layer is the tear film’s outermost layer, which is composed of fat- and wax-like molecules called lipids.

It performs an important barrier function in preventing evaporation of tears and maintaining stability of the

3D printed CONTACT LENSES could beam videos straight into your eyes

  • Scientists from Princeton University in New Jersey have managed to make a 3D printer that can create a five layered contact lens
  • The lens is a transparent polymer with tiny ‘quantum dot’ light-emitting diodes and wires hidden inside that form electrical circuits
  • One layer of the lens beams light into a wearer’s eye – and could in the future be used as a heads up display to show data or even videos
  • The US Air Force is funding the research and hopes that it could one day be used to show pilots information and monitor their health and alertness

Contact lenses with built-in video could be 3D printed

Who needs Glass when you’ve got contact lenses that can display video and even detect health problems? What’s more, lenses with these capabilities could one day be created using a 3D printer. Most of today’s 3D printers work with scraps of plastic or metal and turn them into simple objects. But Michael McAlpine at Princeton [...]

Contact lenses a main source of U.S. eye infections, CDC reports

Researchers say contact lenses worn overnight or not properly cleaned and stored can create an opening for keratitis.Wikimedia Commons   NEW YORK — A new government report says sloppy care of contact lenses is a main reason for hundreds of thousands of eye infections each year. The reports estimates that there are nearly 1 million [...]
