It is now possible to achieve pediatric vision testing in a school setting or in medical fairs thanks to revolutionary vision testing device known as the vision screener. This is a device that works in amazing manner and is able to capture several details from the eyes, perform measurement and compare them to predetermined data and give back results in a fraction of a second. It is now common in health fairs, preschools and grade schools, medical institutions and may also be available in hands of pediatricians and family doctors as it is not restricted to opticians only.
The devices enjoys support from published testimonials and findings in medical journals majority of which are validated and have been commissioned by renown medical professionals. The public on the other hands have added their support in praising the level of efficiency and importance of these devices. There are used by school nurses, pediatricians, opticians and Lions club because they are very easy to use. In fact, one does not need any medical background to use one and interpret the results.
Among several other features, the vision screening device gives results with proven accuracy and screens both eye balls simultaneously. In addition to this, the screening is done at a distance of one meter away (3.3 feet) from the camera. It lasts for only 0.8 second and displays results automatically on the screen. This makes it very easy to use and interpret the results that can also be stored in a data base for later reference through the various documentation options available.
For this reason, both the use and result interpretation is very easy and you can also take advantage of the documentation options that are available. The operational procedure for the device is very easy and takes less than one second for the display of results. It is for this reason that even non-medical staff finds it easy to conduct vision screening.
In order to come up with results, the measurements performed include determination of refraction size, pupil size and the corneal reflexes. These are then compared to referral criteria that are age based. For anisometropia, refractions of both eyes are compared while corneal irregularity is determined for astigmatism.
The diagnosis for astigmatism on the other hands depends on determination for cornea irregularities. For hyperopia and myopia, the farsightedness and nearsightedness are performed respectively. The pupil sizes are compared for anisocoria while the symmetry of eye alignment is necessary for the cornea reflex.
The comparison of refraction of the two eyes is done for anisometropia while astigmatism is diagnosed by determining the cornea irregularity. For myopia and hyperopia, the nearsightedness and farsightedness are determined respectively. Other conditions that can be detected include anisocoria through the comparison of the two pupil sizes corneal reflexes which requires that symmetric eye alignment is determined. All these are done automatically after which the result is displayed.
This can either be a PASS that indicates that all measurements are within the normal range and hence none of the conditions has been detected. In case any of the measurement is not within the normal range, a REFER is the result displayed and it requires visiting the optician.
