Lined trifocal glasses are a type of eyewear designed for individuals who require vision correction at multiple distances while working in environments where eye protection is necessary. These glasses have three distinct sections or focal areas in the lenses, each with a different prescription strength to help the wearer see clearly at different distances. The three main sections typically include:

1. Distance Vision: The upper portion of the lens is designed for clear vision at a distance. This is useful for tasks that require looking at objects or information further away, such as monitoring equipment or reading signs.
2. Intermediate Vision: The middle portion of the lens is designed for intermediate vision, which is helpful for tasks at arm’s length, like reading a computer screen, working on machinery controls, or performing tasks on a workbench.
3. Near Vision: The lower portion of the lens is for close-up or near vision. This is beneficial for activities that require focusing on objects up close, such as reading small print, inspecting fine details, or performing intricate work.

It’s essential to have lined trifocal glasses properly fitted and prescribed by an eye care professional to ensure that the prescription is accurate. Additionally, anti-scratch and anti-fog coatings may be applied to the lenses for added durability and comfort, especially in challenging conditions.

Trifocal lenses operate by dividing the visual field into three distinct zones, each serving a specific purpose. Here’s a breakdown of their functioning: The lower part is for reading and close tasks. The middle zone suits tasks such as computer work and focusing on nearby objects. The upper part ensures clear distance vision for activities like monitoring machinery or enjoying a view.

At RX Safety, we recommend that the segment height (seg height) for lined trifocal lenses be measured so the top line of the intermediate segment (the middle section) aligns with the lower edge of your pupil. This ensures:

Clear Intermediate Vision: Perfect for tasks like using a computer or reading at arm’s length.

Convenient Near Vision: The bottom segment is for close-up tasks like reading books or looking at your phone.

Uninterrupted Distance Vision: The top part of the lens stays clear for seeing far away.

The main difference between lined trifocals and no-line progressive trifocals is the presence of visible lines on the lenses. Lined trifocals have distinct lines separating the three focal zones for distance, intermediate, and near vision. In contrast, no-line progressive trifocals have a seamless transition between these zones, without visible lines.
