Researchers From The Hong Kong University Of Science And Technology,

 have made an amazing break through,

a new prototype lenses can successfully monitor changes in intraocular pressure ( the pressure within the eyeball), photograph BBC the new prototype lens can change in shape to monitor the changes within the eyeball, as the Conversation details:

The continuous monitoring provided by the contact lens could come in handy for people suffering from glaucoma. This lens can monitor changes in intraocular pressure throughout the day, and can responsively release drugs to alleviate the glaucoma. A similar lens, called Sensimed Triggerfish, has received regulatory approval in the United States and Japan.

Thanks to the ubiquity of electronic devices, we are currently living in a world constantly bathed in electromagnetic radiation. Although a clear consensus is absent, studies have pointed out that exposure to electromagnetic radiation could possibly induce some effects in human tissue. Engineers in South Korea have applied a layer of graphene to contact lenses to help shield the eyes from electromagnetic radiation. The thin graphene layer also reduces dehydration, what an amazing invention being able to monitor eyeball pressure changes throughout the day.
