BVAX Service Standard

“Eye examination with the BVAX 16-Step Standard” — one of the most important processes to ensure you get the best eyewear and lenses.

What is an Eye Examination?

An eye examination is the process of checking and testing vision in order to detect visual abnormalities and determine the most accurate prescription for making eyeglasses. This involves measuring vision at both near and far distances, such as reading letters, numbers, or symbols from a set distance. The process is a fundamental step to ensure that wearers receive lenses that precisely match their vision needs, providing clear and comfortable eyesight.
