What are progressive lenses?
Progressive lenses are a special multifocal lens type designed for people who need corrective lenses to see objects at near, intermediate, and far distances. A progressive lens consists of three components:
- A progressive lens’ top portion gives you the clarity you need to see far away.
- Its lower portion gives you the clarity you need to see a close-up.
- The central part aids with clear vision at intermediate or moderate distances.
How effective are progressive lenses?
Progressive lenses allow you to see correctly at different distances without using a bifocal line. It also provides an easier, more realistic solution to age-related vision problems.
Advantages of progressive lenses
- A single set of glasses for all purposes
- No bifocal line to detract from
- Modern, young eyewear
Disadvantages of progressive lenses
- Adaptation time is required from one to a few days or more depending on the lens design, use, and expectation.
- Lateral distortion: the blur can be lesser in high-end modern designs or negligible.
- Higher price
Who should wear progressive lenses?
Progressive lenses are designed to meet the visual needs of people who require correction for multiple viewing distances. If you have trouble concentrating on close-up tasks like reading a book, intermediate activities like using a computer, as well as distant objects, progressive lenses might be the perfect solution. These lenses eliminate the need to switch between multiple pairs of glasses, providing a smooth transition between different focal points.
What is Occupational Lenses?
Lenses created for use in constrained workplaces are referred to as occupational lenses. These types of optical lenses are guaranteed to provide a very clear vision for close work and computer use, but only to a maximum distance of 4 meters.
How effective are occupational lenses?
These lenses are becoming “first choices” in giving a significantly improved visual experience due to the growing need for working in smaller spaces. It also provides superb vision at various operating distances with the utmost comfort and clarity.
Advantages of occupational lenses
- Reduced Eye Strain
- Reduced Headaches and Migraines
- Improved posture and accordingly prevented neck and back pain related to incorrect posture for sitting on the computers.
- Provided with special filters to protect the eyes from UV and harmful digital blue rays.
- Prevent the development of eye-related disorders
What is the difference between occupational and progressive lenses?
Most patients discover that they like wearing their progressive lenses for day-to-day comfort. Without having to switch between a second or third pair to observe objects at various distances, it provides them a great deal of comfort at all of their viewing distances.
Optometrists also advise wearing occupational optical lenses to improve visual performance and reduce eye strain while working because working conditions have changed due to the growing use of computers.
An occupational lens has a substantially larger intermediate field of view than a “typical” progressive that minimizes ocular tiredness and maximizes visual function.
