What is a progressive lens?

A progressive lens is a lens whose upper sides are used to see far, and the lower side is used to see near. The distance from the fixed distance power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power.

Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses. However, is progressive lens good for eyes?

Does the phone screen have irregular color bars when wearing polarized lenses?

It is mainly the special properties of the polarizing film. The polarizer is able to see the internal stresses in the plastic, so when we usually look at the edge of the mobile phone screen, it will have a colored stripe or a black piece, which is mainly caused by the uneven edge pressure when the screen is installed. It's mostly a matter of light and shade. Wearing a polarized lens to see the LCD screen a tilt will find that the screen darkens, mainly because the polarizing lens can absorb light in a certain direction. The LCD screen is a one-way light (different from sunlight), so it is absorbed, so it is found to be dark.


Choose a quality progressive lens.

Superior progressive lenses provide a better viewing experience. They also remove any distortions you might feel when reading what's in front of you. Lenses can also be coated with special coatings. Anti-reflective coating can prevent glare on the road, and anti-scratch coating can reduce wear marks.



How to Get Used to Progressive Lenses?

How to adjust to a pair of new glasses? How long does it take to adjust to a new pair of glasses? In general, there are several ways for adjusting to progressive lenses. In this section, we will show you some of them.

What is the cheapest way to buy prescription glasses?

After the examination, you will bring your optometry sheet and go to the optician to match your glasses. Note that the optical shop has professional qualifications. The refractive index of the resin lens, such as 1.49, 1.56, 1.61, 1.67, and so on, mainly depends on the degree. If the degree is not high, 1.56 will do. In addition, the sophisticated store will also measure the nose height, nose width, the distance between the eyes and ears, and the forward angle of the frame, which are also indicators of whether the glasses are comfortable to wear. It is recommended to try them on after they are fitted, and the time to try on them should be longer, so as to determine whether the glasses are suitable.
