Final answer:
To adjust Bausch and Lomb multifocal lenses for near vision complaints, one should typically increase the near power. However, adjusting the multifocal design might be necessary based on an individual's specific needs and usage. Increasing the distance power does not remedy near vision issues.
Step-by-step explanation:
If a patient has complaints about near vision when using Bausch and Lomb multifocal lenses, the proper course of action would typically be to increase the near power of the lenses. This can be done because multifocal lenses have different areas designed for close-up and distance vision, and an adjustment to the near segment of the lenses can help improve the focus for near tasks. However, in some cases, it might be necessary to adjust the multifocal design depending on the specific vision needs and the way the patient uses their eyes for near activities. An optometrist would analyze the situation considering factors such as the existing lens power, the visual demands of the patient, and whether the issue lies in the lens design or the power allocated for near vision.
Common symptoms of near vision problems may include blurred vision when reading or doing close work, eyestrain, or headaches. Sometimes, simply increasing the near power can alleviate these symptoms. Nevertheless, if the multifocal design is inappropriate for the patient's visual habits, adjustments in lens design may be needed. It's worth noting that increasing the distance power is not a solution for near vision complaints, as this typically affects the clarity of vision at farther distances.
