Product Features
Progressive lens solves the problem that middle-aged and elderly people need different brightness to see objects at different distances and have to frequently change eyeglasses. A single pair of progressive eyeglasses can be used for seeing far, middle and near distances.
How do progressive lenses work?
There are three major vision areas of a progressive lens:
1. Distance Vision: The distance vision is located at the upper part of the lens. Its degree can help you see far-distance objects clearly when driving or viewing scenery.
2. Near Vision: The lower part of the lens is used for near vision. It is suitable for reading books or other up-close activities.
3. Intermediate Vision: The middle part of the progressive lens connects the upper two visions, known as the transition zone. It gradually and continuously transitions from the distance to the near, providing correction for intermediate vision. So, you can use it to observe objects at medium distances. This is suitable for activities such as using a computer or watching TV.
What are the benefits of progressive lenses?
1. Seamless Multifocal Vision: Progressive lenses integrate distance, intermediate, and near vision corrections without visible lines to achieve natural transition between different distances.
2. Relieve Eye Fatigue: When using progressive lenses to view nearby objects, you don’t need to overly use the ciliary muscle for adjustment, which can reduce the risk of ciliary muscle spasm and effectively relieve eye fatigue.
3. Convenient to Use: Progressive lenses offer all-in-one vision correction for daily activities. They can be worn by individuals with myopia, presbyopia, or astigmatism. You don’t need to change the eyeglasses frequently. All-in-one single lens.
4. Customization: Tailored to individual prescriptions and lifestyle needs. The options include different corridor lengths for specific tasks (for example, an extended intermediate vision zone for office work).
