The MTI PhotoScreener is the worlds only portable, instant vision screening device.

The MTI PhotoScreener detects vision disorders that can lead to amblyopia including near-sightedness, farsightedness, astigmatism, strabismus, and cataracts. No other adequate methodology to identify serious eye disorders in infants, toddlers and other difficult-to-screen children exists.

It is the first screening device to use instant film, allowing for immediate interpretation.

The PhotoScreener works effectively on young children and developmentally challenged individuals without dilation of the eyes or head restraint.

Amblyopia or "lazy eye" is the leading cause of monocular blindness. It develops rapidly in the first three years of life and is treatable if detected early, usually by age five.

Approximately 1.2 million American children - or 1 in 20 youngsters - between the ages of 6 months and five years have a serious eye disorder.

Most children get their first vision test at age 5 or 6, often too late for corrective treatment of amblyopia. By the time the child reaches seven years of age, treatment for amblyopia is virtually ineffective and blindness can occur.

Only 21% of pre-school children in the United States are screened for either strabismus or amblyopia.

The MTI PhotoScreener is a patented, computerized camera that takes an instant photograph of the eyes. Images in the form of white crescents appear in the photograph if problems are detected. The camera weighs about six pounds and uses a special high speed(ISO 3200) Polaroid film.

The PhotoScreener was invented by an American pediatric surgeon and ophthalmologist. Polaroid Corporation provided technology assistance during the product development.
