With nearly 125 million people worldwide wearing contact lenses it was only an amount of time before they became more technical, and we found 4 new technical advancements that are pretty futuristic and helpful, take a look for yourself:
Medication: With an estimated only 5% of eye drop medication (for glaucoma especially- which is a build-up of pressure in eye) making it to the affected areas, researchers have developed contact lenses embedded with microscopic diamonds loaded with glaucoma medication (timolol maleate). When the medication comes into contact with an enzyme in tears this triggers the slow release of the drug into the eye, making the lenses a great benefit to patients with glaucoma, allergies or eye infections.
Zoom: Swiss researchers are developing contact lenses that contain tiny lenses to boost vision and are able to zoom in and out with the wink of an eye. The new contact lens contains an extremely thin, reflective telescope which is activated by a wink. The wearer winks with the right eye to activate the telescope and with the left in order to deactivate.
The research company is developing the contact lenses to help those with age-related macular degeneration disorder (AMD). The device magnifies objects 2.8 times, meaning that AMD patients can read more easily and are able to better recognize faces and objects.
Blood sugar: Scientists from Google are working on a hassle-free method of checking glucose levels with a contact lens that measures the amount of glucose in the individual’s tears. The lens uses a miniaturised glucose sensor embedded between 2 layers of lenses and a tiny wireless antenna, which connects remotely to a smart phone or computer.
Researchers are also working on adding tiny LED lights into the lenses which could light up to indicate that glucose levels are low enough that the patient needs a dose of insulin.
Projections: In the apparent next few years there will be contact lenses allowing information such as text messages, emails and driving directions to be projected onto the contact lens itself, using a spherical curved LCD display installed into the lens.
With all these advancements being promised in the near future it looks like those 125 million contact lens wearers won’t be complaining as much.
