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.
This important device is supported by a list of impressive testimonials resulting from validated studies which are qualified by positive reviews from the general medical profession and the public. It is so easy to use hence preferred by pediatricians, Lions club and school nurses. Given that the only necessary compliance is a short fixation of camera, this form of screening works for all children. The device works by producing a specially designed sound targeted to provoke the fixation.
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.
This means that even non-medical staff can actually perform the screening. The person to perform screening starts by pulling the camera trigger to start; this is followed by a sound that is meant to attract attention. The image of both eyes is captured on a white triangle on the screen that then allows for performing the necessary measurements. The recommended screening distance is one meter (3.3 feet) from the camera. The tolerance level is +-5 centimeters or +-2 inches. The results are then displayed on the screen in a matter of seconds.
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.
There are several conditions that are detected after the performance of a number of measurements and tests which revolve around measuring and comparing the sizes of cornea reflexes, the pupil size and the refraction size. These data is then compared to predetermined data used for referral.
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.
The results can be saved and printed in different formats thanks to an internal database. The database makes it possible to review the previous records in an organized or chronological order. In addition to this, the device is also cheaply available hence saves a lot of money and time that could be wasted in having to visit an optician.
