Lenses
We use only the safest lens material available: Polycarbonate. This ensures that every pair of prescription safety glasses we make is made to high impact standards. All lenses are hard coated on both sides to help prevent scratching.
Single vision lenses have one focal distance. They are used by people who are near or farsighted, and do not yet need a bifocal to help with reading. However, if a person does normally need a bifocal, they can decide to have lenses made for distance, intermediate or near vision.
A FT28 (Flat top, 28 mm wide) bifocal has the majority of the lens made for distance vision with a segment used for reading. If needed they can be made with distance or computer vision in the top with either computer or reading in the segment.
A FT-35 (Flat top, 35mm wide) bifocal has the majority of the lens for distance vision with a segment used for reading. The segment is wider than the FT-28 giving a wider near viewing area. The lens can be made with distance or computer vision on top and computer or reading vision in the segment.
The 7×28, 7mm deep intermediate section and 28mm wide trifocal, has the top part of the lens for distance vision, the intermediate ribbon for computer distance vision and the lower part of the segment for reading vision.
The 8×35, 8mm deep intermediate, 35mm wide trifocal, has the top part of the lens for distance vison, the intermediate ribbon for computer distance vision, and the lower part of the segment for reading vision. The segment is 7mm wider than the 7X28 allowing for a wider viewing area.
We use the Dimension Digital progressive lens, one of the most technologically advanced lenses available. It minimizes side distortion with wide clear viewing areas. The progressive lens is a very good all around lens. The top part of the lens is for distance vision and the bottom of the lens is for reading vision. From top to bottom, the power is gradually changing. As depicted the distance area is the widest, the intermediate is narrowest, with a widening reading area. To have a lens with no lines, the periphery of the lens is not optically as good as the center, so these lenses may take some time to adapt to, if you don’t already wear them.
