It is best to detect any eye disorder early as this make most treatments easy as less costly. For this reason, children are taken through vision screening starting from early age. Conducting this form of screening without having to visit an optician could have been impossible if not for a vision screener which has made it a cheap and easy venture on a large scale in community settings such as health fairs, fun days, preschools and grade schools, churches, medical centers and even the pediatrician clinics or at homes.
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.
The only required compliance is a short camera fixation. It has high level of accuracy and the results can be fully trusted. It is also able to screen two eyes all at once and the distance required for screening is about one meter or 3.3 feet from the camera. After just 0.8 seconds, the (PASS or REFER) results can be displayed on the screen automatically.
This simplicity in operation makes it possible for any ordinary person with no training to be able to perform the screening. When the person to be screened is in the correct position, the device trigger is pulled. This result to a unique sound that helps achieve fixation after which the images of eye balls are captured on a white triangle on the screen. Several measurements then follows after which the results can be displayed. The tolerance level is set at +-2 inches or +-5 centimeters.
The measurements performed revolve around refraction size, the size of the pupil and the cornea reflexes. These are then compared with the data used for referral to determine if they are within the normal range or not and the PASS or REFERAL results is then generated. In order to diagnose anisometropia, the refractions of both of the eyes are compared and the deference compared with the standards reference.
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.
All the measurements are automatically performed followed by a PASS which indicates that all the measurements for all the conditions are within the normal range. In case one or more measurements does not fall within the normal range, the REFER measurement will be 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.
