Currently, the most common treatment for glaucoma is medication in the form of eye drops. Used every day, eye drops are effective, but they may cause a range of side effects, including itchiness, red eyes, and blurred vision. 

One day, eye drops could be replaced with a pair of glasses, outfitted with an electromagnetic coil, to treat glaucoma. Learn more about how these special glasses work and the research findings behind them, as well as who they may benefit.*  

How do the glasses work? 

Glaucoma develops when fluid builds up in the front part of the eye, increases eye pressure, and damages the optic nerve. These special glasses would allow for natural drainage to work more efficiently and decrease eye pressure. 

Developed by Bionode LLC, a Purdue University-affiliated start-up, the glasses contain a metal coil that generates an electrical current to go through the muscles of the eye. This electrical current stimulates the drainage angle of the eye, allowing fluid to drain out more efficiently. 

Are they safe? 

While the research is not yet complete, Dr. Ike Ahmed, a clinical investigator for Bionade LLC, believes they are safe. “Instead of using drops, we’re using low-voltage, safe electromagnetic current in the glasses that reach the eye.” Dr. Ahmed also says early studies, which are still ongoing, have shown no pain, discomfort, or side effects for patients wearing the glasses.  

Are they effective?

There is still much to learn about the effectiveness of the Bionode glasses, as human studies have just begun. Researchers do feel optimistic since animal studies showed Bionode glasses lowered intraocular eye pressure (IOP) within 10 to 15 minutes.  

Who could these eyeglasses benefit?  

If effective, this treatment option could benefit a wide variety of patients, from people in the early to late stages of glaucoma. The Bionode eyeglasses could be used to replace eye drops or in conjunction with eye drops. It may even be helpful for patients with advanced glaucoma who have had surgical treatment.
