Smart Contact Lenses

Yesterday’s post featured a video that demonstrated the capabilities of the iOptik contact lens.  Specifically, it showed the ability of a lens to simultaneously focus on both extreme distance and near objects.  The idea is to use such a lens to allow wearers to view multimedia displays inside their eyewear.

Today’s video features contact lenses used in a slightly different way.  It’s no surprise that contacts with embedded circuitry are being developed, and the video shows a few uses already in the works.  One type of lens can monitor the eye pressure of people with glaucoma.  Another can monitor the blood sugar of people with diabetes.  Still others can slowly dispense medicine and even allow wearers to view multimedia displays right before their eyes.

The eye doctors and staff at LaFollette Eye Clinic look forward to the day when contact lenses do so much more for the vision and health of our patients.  Thanks to the Pittsburgh affiliate of CBS for the video.  There’s a commercial, but the video’s worth the wait:

iOptik Contact Lens Demo

Here’s an interesting video by Innovega, the makers of the iOptik contact lens.  The demo shows how it is possible for a single lens to simultaneously focus at a far distance and an extremely close distance.

So what’s the point?  This technology is being developed so wearers of the contact lenses can put on electronic eyewear that contains multimedia screens and enjoy hands free operation.  Obviously you would not use this system while driving as it would obscure vision. But we highly discourage using any multimedia while driving anyway.

Of the many proposed uses of electronic glasses this is one the eye doctors and staff at LaFollette Eye Clinic feel has many potential uses.  Enjoy the video:

Cheap Contact Lenses Harmful to Teenager’s Eyes

Non-prescription contacts are causing serious trouble for this unfortunate teenage girl

In a previous post I blogged about contact lenses causing a significant number of ER visits for kids.  And while statistics are helpful, sometimes stories about individuals can be more compelling.

Here’s a story about Erica Barnes, a 14 year old from Queens, New York.  She bought colored contacts without a prescription, training, or evaluation by an eye doctor.  After falling asleep in the lenses she developed a severe eye infection that hospitalized her for two weeks.  She now faces the sad choice of either losing vision in the infected eye or going through with a corneal transplant.

The video below makes some significant points.  First, she did not seek an eye doctor to obtain her lenses.  Had she done this, she would have received a proper exam, evaluation, and training.  Second, she developed the infection one day after inserting the lens.  It does not take long for serious eye infections to begin and do severe damage.  Third, she was told to rinse her contact lenses in tap water, which is very dangerous.  Some “vendors” offering non-prescription contacts neither know nor care about proper, healthy contact lens wear.

The video also acknowledges the growing popularity of colored contact lenses due to high profile celebrities using them in videos and on stage.  However, these celebrities are not risking their fame, careers, and vision by using store-bought or non-prescription contact lenses.  Rest assured: the stars are receiving proper contact lenses and care from their eye doctors.

Selling any contact lenses without a doctor’s prescription is illegal.  This includes “plain” colored lenses without power or magnification.  It is illegal because contact lenses are medical devices regulated by the FDA, and wearing illegal contact lenses can be very unhealthy and harmful to the eyes.  If you want contact lenses, either with power to correct your vision or with color (or both), be sure to seek out a qualified eye doctor to help you.  It is simply not worth risking a lifetime of visual problems.
