      Many people avoid eye tests, complaining about lack of money or time, you need to visit a specialist. But soon, these excuses are no longer relevant. American scientists have developed an inexpensive device that allows the smartphone to make high-quality images of the eye.

      Experts promise that after a simple exercise to make a detailed snapshot of the front and rear parts of the eyeball everyone can. The resulting data is transmitted ophthalmologist for detailed study and stored in the electronic medical record of the patient, the British newspaper The Daily Mail.

      Robert Chan, co-author and assistant professor of ophthalmology at Stanford University School of Medicine, calls his design "Instagramom for eyes» (Instagram - application for sharing photos and video). He and his colleagues believe that this technology will be able to make eye care more accessible, and allow doctors to counsel patients at a distance.

      It should be noted that the specialized ophthalmic equipment worth tens of thousands of dollars, and to use it requires serious preparation. In addition, not all inhabitants of the planet have access to such services.

      Using smartphones to monitor the state of true where there is no opportunity to be a full examination by a specialist, or at the time of first aid - says the technology study's lead author and an ophthalmologist David Myung.
      Scientists note that modern smartphones are not only good cameras, but also support high-speed data, so you can send photos to a medical facility for a few seconds. Described in the technology is a step towards a remote health diagnosis, they believe.

      It should be noted that the market already has overhead microscopes for smartphones that can make detailed pictures of eyes, but they are not as convenient to use as a device created by physicians at Stanford University. This is especially important when seconds count.

      The product was created from parts printed on the 3D-printer. The work was published in Journal of Mobile Technology in Medicine.

      It is reported that in the near future will be conducted extensive clinical study on the quality of images obtained with the use of new technology. You will then be able to monitor the state of tested eye in people with diabetes.
