With a smartphone, not only ophthalmologists but also non-ophthalmologists can acquire slit lamp images anywhere eye medical care is difficult to reach, for example, distant, sparsely populated areas, home health care, EMS, disaster areas, developing countries, etc..
Non-ophthalmologists on site can send the slit lamp images taken by MS1 to an ophthalmologist for thorough diagnosis.

Medical examinations and diagnoses using MS1 are useful not only for initial treatment such as prescribing eye drops available in the local area, but also for referral to ophthalmology hospitals in urban areas for highly specialized treatment.
Examples of diseases and signs for which MS1 was useful for diagnosis:
High-brightness LED provides up to 40,000lux.

*Slit illumination width and illumination angle are not variable.
Forehead and cheek rests are designed to fix the device in position for stable photographing.
