About eighty percent of the blindness that occurs is preventable and most of the blindness cases occur in Africa and Asia, why? Because in Africa and Asia, there are still many rural areas without adequate health facilities, without a specialist eye and also the difficulty of transportation to health centers. So that patients prefer to work – and hope her condition gets better by itself than on going medical treatment. This is the underlying invention Peek (Portable Eye Examination Kit) by a team of researchers from the London School of Hygiene and Tropical Medicine, United Kingdom.
Peek magnifying lens is essentially connected with the camera smartphone. Peek is used to observe the fundus of the eye area (Figure 1) so that it can serve as a substitute for conventional instruments (Figure 2) are commonly used by eye doctor that cost much more expensive and bigger. Peek small sized (Figure 3) so that the portability that allows eye doctor or medical personnel visit the patient and do medical check in their home. Peek is used with the direct lens Peek preinstalled on Smartphones to the patient’s eye lens. The bottom lens Peek have a light that will shine up to the fundus of the eye, light refracts out and was caught by the lens, the camera passes go Peek smartphone. On the smartphone there is software for processing images obtained.

Peek can be operated by all the people, but not everyone is able to interpret the images. These images can be sent to the team eye doctor via the internet which will then judge it. In this way, even communities in isolated areas once can receive better health care.
