What is the appropriate focal length for the bifocal lenses?

To fit a person with bifocals, it is important to consider their near vision and distance vision requirements. In this case, the person can see clearly when the object is between 38.4 cm and 2.2 m from the eye.

Based on this information, we can determine the appropriate prescription for the bifocals. Typically, bifocals consist of two parts: the upper part for distance vision and the lower part for near vision.The distance vision prescription is used for objects that are farther away, while the near vision prescription is used for close-up tasks such as reading or using a computer.To determine the specific prescription values, it is recommended to consult an optometrist or ophthalmologist. They will conduct a comprehensive eye examination and prescribe the appropriate bifocals based on the person's individual needs and visual acuity. The prescription will take into account the person's distance vision and near vision requirements, ensuring that they can see clearly at various distances.
