Progressive Lenses
Definition of Progressive Lenses
Progressive lenses, also known as multifocal lenses, are advanced corrective eyewear designed to address vision issues at varying distances. Specifically catering to presbyopia, a natural condition typically occurring around the age of 40 to 45, these lenses seamlessly adapt to near and far vision needs. The entire height of the lens provides a variable field of vision, offering a smooth transition between reading and distant activities.
Who Needs Progressive Lenses?
Typically prescribed by ophthalmologists for those experiencing presbyopia, progressive lenses eliminate the need for multiple pairs of glasses. The lenses cater to individuals requiring correction for both near and distant vision, providing uninterrupted visual comfort throughout the day.
Different Areas of Vision
Progressive lenses feature a dynamic field of view extending across the entire lens height. The lower half optimally corrects close-distance vision, around forty centimeters, while the top half addresses distant vision. Connecting these two focal points is the corridor, facilitating a seamless transition between near and far vision. This corridor also corrects intermediary distances, such as those encountered when using a computer, working on a surface, or reading musical notes.
Progressive Lenses - Correcting Multiple Distances
Unlike single vision lenses, progressive lenses correct various viewing distances on a single lens. While this feature enhances convenience, it introduces distortion zones on the sides due to the progression track. The width of the mean viewing corridor and the pronounced distortion areas depend on the type of varifocal lens chosen.
Different Generations of Progressive Lenses
Visionet offers three types of progressive lenses, distinguished primarily by the width of the progression channel. The Vision Standard lenses provide an excellent price-performance ratio, followed by Vision Large lenses and Vision Extra Large lenses with an exceptionally wide progression channel for optimal vision in diverse situations.
Choosing the Right Progressive Lens
The choice of progressive lenses depends on your budget, activities, and correction needs. For stronger prescriptions, high-quality progressive lenses with optimized profile channel geometry are recommended. However, for minimal corrections and budget constraints, entry-level progressive lenses still offer impressive performance. Active individuals engaging in frequent close-range activities are advised to choose lenses with a large or particularly large field of vision for enhanced visual comfort.
Treatment Options for Progressive Lenses
Since progressive lenses are worn daily, they can be treated similarly to single vision lenses. Visionet offers treatments such as hardened treatment (resistant to micro scratches), anti-reflective coating, Max UV anti-reflective coating, or anti-reflective filter + against blue light for all varifocal lenses, including entry-level options.
Additional Options for Progressive Lenses
Depending on usage, progressive lens wearers can opt for tinted lenses to create progressive sunglasses. Those engaged in outdoor activities may choose photochromic or polarized treatments. Strong prescriptions can be accommodated with various index options, including standard index 1.50, progressive lenses index 1.60, index 1.67, and index 1.74, with Visionet providing personalized recommendations based on the prescription.
Adapting to Progressive Lenses
Dispelling common misconceptions, progressive lenses offer quick adjustment times and lasting comfort. Coordination between the eyes and brain adapts swiftly to the varying areas of vision. Advanced technologies consider natural vision and eye physiology, eliminating the need for awkward postures. Maintaining a natural gaze allows wearers to comfortably enjoy the benefits of progressive lenses.
Tips for Progressive Lens Wearers
- Correct posture in front of a computer to alleviate neck pain.
- Begin using progressive lenses promptly after recognizing presbyopia for easier adjustment.
- For first-time wearers, gradually increase wearing time in the initial weeks after purchase.
- Be mindful of minor adjustments needed in specific situations, such as descending stairs or watching TV in a reclined position.
- Choose a frame you like to enhance your commitment to wearing glasses and ease the adjustment process.
- Consider having a second pair of glasses for added convenience, as adjusting to progressive lenses makes returning to conventional lenses challenging.
