The PRIO Computer Vision Tester; Is It A Useful Tool Or Merely A Gimmick?

Many people suffer from Computer Vision Syndrome of CVS. CVS can cause a variety of symptoms, many of which are related to the eye. The PRIO Computer Vision Tester has been manufactured to more accurately determine what spectacle prescription should be given specifically for computer use. Differences in computer spectacle prescriptions have been noted using the PRIO Computer Vision Tester versus those found using more traditional methods. This study has been conducted to determine the quantity of these differences as well as to determine if a consistent factoring figure can be used in conjunction with traditional methods to mirror the results of the PRIO Computer Vision Tester. The results of this study concluded that there is in fact a considerable difference in the final computer prescriptions found using the PRIO Computer Vision Tester and the commonly used Snellen acuity card. A consistent subjective factoring figure was not found due to the variances found from patient to patient. However, an objective factoring figure could have been taken into consideration with the majority of the patients studied.
