Preclinical Presbyopic Development
Determination of the amplitude of accommodation using subjective methods is the most common clinical practice, and for a great number of years since Donders, subjective methods have been used in the laboratory as well. Although objective methods are available, they often require the employment of special procedures such as the use of infrared light, ultrasound, or photography (see Appendix).
