1.56 Progressive Blue Cut Green Coating Optical Lens - High-Definition Eye Protection by China Suppliers and Factory
Historical Background
Progressive lenses are developed on the basis of bifocal lenses. The use rate in Europe and the United States is relatively high, and the time of matching in China is nearly 10 years. The progressive piece is in the transition of the upper and lower two focal lengths, the use of polishing technology, the gradual transition between the two focal lengths, that is, the so-called gradual, it can be said that the progressive lens is a multi-focal length lens.
When the wearer observes far/near objects, in addition to not having to remove the glasses, the movement of sight between the upper and lower focal lengths is also progressive, there is no dual-focal length when the eye must constantly adjust the focal length fatigue, and there is no obvious dividing line between the two focal lengths. The disadvantage is that there are different degrees of interference areas on both sides of the progressive film, which will cause the peripheral visual field to produce swimming motion.
Characteristic
1.56 Main features of progressive anti-blue lens:
-
1.56 refractive index lens: Suitable for mild to moderate myopia or farsightedness patients, the lens is relatively thin and lightweight.
-
Progressive design: Provides different degrees from top to bottom, suitable for presbyopia patients, and can see far, middle and near objects at the same time, without frequent replacement of glasses.
The lens has an anti-blue light coating, which can effectively filter the harmful blue light emitted by electronic devices, reduce eye fatigue and dryness, and protect the retina.
Applicable population
-
People who use electronic devices for a long time: such as office workers, students, etc.
-
Presbyopia: People who need to correct both farsightedness and nearsightedness.
-
Eye health: People who want to reduce the damage blue light does to their eyes.
Advantage and Precautions
Advantage:
-
Versatile: Corrects vision and protects blue light at the same time.
-
Convenience: Progressive design eliminates the need for frequent mirror changes.
-
Comfort: Reduce the fatigue of the eyes for a long time.
Matters needing attention:
-
Adjustment period: The first use of progressive lenses may take time to get used to.
-
Professional optometry: It is recommended to take optometry in a professional institution to ensure the accuracy of the degree.
-
Lens care: Clean regularly to maintain anti-blue light effect.
Progressive lenses are a powerful and beautiful vision tool for people who need multi-focal correction.
Frequently Asked Questions
What is the difference between progressive lenses and traditional bifocal lenses?
Unlike traditional bifocal lenses which have a sharp dividing line, progressive lenses use advanced polishing technology to create a gradual transition between the upper and lower focal lengths. This allows the wearer to see far, middle, and near objects smoothly without a visible dividing line, reducing eye strain and fatigue.
What are the benefits of the 1.56 index progressive anti-blue lens?
The 1.56 index lens is lightweight and thin, making it ideal for mild to moderate vision correction. It combines multi-focal clarity for various viewing distances with an anti-blue light coating that filters harmful blue light from digital screens to prevent eye dryness and fatigue.
Who should wear progressive anti-blue lenses?
These lenses are perfect for individuals with presbyopia who need vision correction for both near and far distances. They are also highly recommended for office workers, students, and anyone who spends long hours using electronic devices and wishes to protect their eyes from blue light.
Is there an adjustment period for new progressive lenses?
Yes, first-time wearers of progressive lenses usually require an adaptation period. Because there are slight distortion/interference areas on the outer edges of the lens, your eyes and brain will need a little time to adjust to looking through the correct zones of the lens.
How should I care for my progressive anti-blue light lenses?
To maintain the effectiveness of the anti-blue light coating and ensure visual clarity, clean your lenses regularly with a professional lens cleaner and a microfiber cloth. Avoid using harsh chemicals or abrasive materials that could scratch the surface coatings.
