Types of Progressive Lenses: How many types of these eyeglasses are there? Progressive glasses and multifocal glasses are the same. The words are interchangeable in this article.

Intro – Types of progressive lenses

Progressive lens are “multifocal” lenses that offer a smooth progression of several lens powers for very optimised vision across the region. They are usually near distance being at the bottom and far distance viewing at the top part of the lens. You will be able to understand the special characteristics associated with every design by observing how progressive lens are made. Before that, let us introduce the structure or design of a progressive lens.

for progressive lenses pros cons

There are 4 major parts on the lens.

  1. Green : Distance Vision
  2. Yellow : Intermediate Vision
  3. Red : Near Vision
  4. Blue : Blurred area

When multiple prescriptions are compressed into a single piece of lens, there will be distorted or blurred area (the blue area). Wearer will find that the vision is wavy and distorted. A better design lens has wide yellow area also know as the corridor and less distorted area. At the relax mode, when wearer looks far, the eyes will see through the green area. When wearer is doing desk job such as computer or paper work, he or she will see through the yellow area. Lastly, during reading, the eyes will actually look down instead of the entire head moving down. Point to note: this is actually how our eyes move.

We purposely place different prescription at different position to help the eyes. So the key to comfortable vision depends on the precision of the prescription and the design. Now that we have explained the structure, let us see how one progressive lens varies from another.

Point to note: when we talk about better design, we mean:

  1. Smoother transition from distant power to reading power thus reducing waviness
  2. Wider corridor to allow more stable vision

Traditional progressive glasses

One of the old forms in the types of progressive lenses. This form of lenses makes use of semi-finished lens which will are molded with virtually no cylinder (spherical power) at the front. Instead, the particular spherical power will be added at the backside of the lens. However, this sort of progressive lens are becoming obsolete because it isn’t accurate since there are other better choices available where the specific corridors are narrower (the part of the lenses associated with power that corrects your vision).

Digital progressive lenses

This type of progressive lenses designs gives the most optimum view where the particular wearer’s optical needs are taken into consideration in the designing process. The particular difference between digital progressive and traditional progressive lens is digital’s capability to do custom areas within a lens, tailor to an individual’s needs. Digital progressive lenses make sure that the most precise prescription can be tailored according to a person’s face, plus how do you wear your glasses as well as the position of your eye.

DIGITAL FREE-FORM LENSES

The latest types of progressive lenses are digital free-form type. As long as it is available at the glasses store you visit, the opticians will definitely recommend it because they come along with huge benefits.

  1. Custom made individually
  2. Made exclusively for you based on your eyeball viewing habits and viewing patterns

Think about tailor-made coats that fit perfectly.

These lens are particularly tailored uniquely for one prescription, together with frame sizes and position-of-wear. All the points are designed precisely to result in smooth prescription progression and minimise distortion. Besides, since the same spectacle frames may sit higher on one’s face, and lower on someone else’s, we will need to obtain accurate measurements in order to maximise eyesight comfort and optical experience. Digital free-form progressives glasses also offer broader and much more accurate channels plus corridors, which implies that you’ll have better peripheral vision. Besides this, digital free-form progressives also have the particular technology to decrease the particular blurriness around the edges the peripheral view.

Best Progressive Lenses / Best Multifocal Glasses

In determining which is the best progressive lenses or multifocal, we have to look into few attributes i.e. lens coating, visual field, intermediate vision, reading comfort, distortion and adaptation. In terms of lens coating, Hoya has one of the most durable coating called High Vision Long Life (HVLL). It has extremely good scratch resistance coating and comes with two years warranty. For visual field, intermediate vision and reading comfort, we are talking about the lens design. As the power progresses, clear visual field gets narrower. Thus, to determine which lens is better, we need to factor in these 3 attributes. Same as distortion and adaptation, better lens has better vision stability and easier to wear. So back to the topic, for the best progressive lens or best multifocal glasses, we choose these 3 namely Hoya MyStyle, Carl Zeiss Individual 2 and Essilor Varilux S Series.

Summing up

Progressive lenses may seem complicated and cause the feeling of discomfort. However, expectation can be met with proper explanation and measurement. Progressive glasses make wearing glasses more convenient for wearer. Concerned about the price? You can find out more about the range of progressive lenses here.
