Objectives

Narrative objectives1

Nowadays,refractive correction, such as eyeglasses,not only improves vision, but also requires faster and more accurate methodologies to be established. However, it is not clear how much the values vary between methods and other factors, and whether expensive equipment is truly accurate in its measurement. In addition, patients and eyeglass purchasers may find it troublesome to measure subjective refractive values by responding to repeated questions while changing lenses.
In addition, the current practice of adjusting eyeglass power to a weaker value based on the experience of the wearer and expecting the central system to adapt to the eyeglass after the wearer has worn it is a highly uncertain method. As a result, it takes a lot of time to determine a comfortable pair of eyeglasses, and if they still do not fit, it is not uncommon for inefficiencies to result in the replacement of the lenses.
Therefore, we aim to establish a highly accurate methodology in a shorter period of time by verifying refractive values for different ocular refraction testing methods and building a prediction model using artificial intelligence.
