For a very tall person, where should the bifocal segment be placed?

For a very tall person, the appropriate placement for the bifocal segment is below the normal position. This is because the height of the wearer affects the line of sight. Taller individuals often have their reading distance positioned lower due to their body proportions and how they interact with their environment. By placing the bifocal segment lower than the standard position, it allows the wearer to look down comfortably for near tasks without having to tilt their head excessively.

This adjustment accommodates the natural visual habits of taller individuals, ensuring that when they look down, their near vision is more easily accessible. Consequently, it enhances comfort and functionality in daily activities like reading or using digital devices while helping to eliminate unnecessary strain that could occur with improper segment placement.
