Progressive lenses

Proven content

Progressive lenses are useful and make life much easier. However, this is not always the case. You should be aware that they have advantages and disadvantages. Progressive lenses appeared on the market in 1959. So they are not, as it may seem, a new invention. They were called Varilux and were sold by the French company Essilor. Currently, they are in the assortment of many manufacturers who offer them all over the world.

Progressive lenses – what should you know about them?

This is one of the most technologically advanced eyeglass lenses, commonly known as the so-called progresses. They have several areas of vision – the upper part is responsible for sharp distance vision, and the lower and center allow sharp vision of objects closer. Progressive lenses originated in the XNUMXth century and are the next stage in the development of bifocals invented by Benjamin Franklin.

Thanks to progressive glasses, people with visual impairments can clearly see objects in the distance – this is especially important, for example, when driving a car. What’s more, they can also comfortably view objects close by, which allows for comfortable reading or using the phone. Progressing also enables you to see objects clearly at intermediate distances, so they are helpful when using the computer.

Who are progressive glasses for?

Progressive glasses are designed for people around 40 years of age. Then a vision defect may appear, causing the image seen up close to become blurry, and in turn, you can still see sharp objects at far distances. Thanks to progressive glasses, accommodation can be supported. After the age of 40, the natural flexibility of the lens in the eye decreases.

Everyone who is over 40 years old and has a presbyopia should reach for progressive glasses. The process of adapting to wearing them is not cumbersome, provided that the design of the progressive lens is adapted to the lifestyle of the person. It is also advisable to make sure that the vision correction is properly performed. It is equally important to measure the anatomical parameters without errors.

How do you get used to progressive glasses?

People who start wearing progressive lenses find it the most problematic to find the power zone appropriate for the chosen space on the surface of the lens. The cause is the occurrence of aberrations on the periphery of the progression zone – the result is distortion. To prevent distortion of the image, look straight ahead. Do not lower your head when looking into the distance, and tilt your head towards the subject when looking to the side.

In order for the eyes to easily find the zone for closer observation, it is worth remembering not to keep books, telephone, newspapers, etc. in the line of sight, but below it. Conversely, when reading content at eye level, tilt your head back. Adaptation to progressive glasses is a process, but should not take more than 3 weeks of continuous use, otherwise please contact your optician.

Advantages and disadvantages of progressive glasses

Unlike traditional prescription glasses, progression requires a longer adaptation time. For some people, their price is also a disadvantage – even cheaper progressive glasses cost more than traditional glasses. Another disadvantage is that they narrow the image when working at the computer. Eyesight defects, e.g. glaucoma and cataracts, are contraindications to wearing progressive glasses.

The users of progressive glasses appreciate them above all for their multifunctionality. Thanks to them, they do not need to have two pairs of glasses with them, because they combine the properties of reading glasses, computer glasses, as well as walking or driving glasses. Progressions enable comfortable close-up and distance vision, and comfortable switching between the visual zones.

Is the use of progressive lenses safe for health?

This is one of the most common doubts among people who intend to buy progressive glasses. Progressing does not damage your eyesight, provided that they are correctly adjusted. It is also worth knowing that well-chosen progressive lenses even limit the development of eye defects. However, if this could be the case, the selection of glasses should be commissioned to a specialist and not to buy ready-made, usually cheaper progressions, e.g. in a pharmacy. It will end up with permanent vision defects and deterioration of well-being.

What are the contraindications for wearing progressive glasses?

Progressive lenses should not be worn by people who use a computer for many hours a day – multifocal lenses narrow the image and make intensive work in front of the monitor much more difficult. Other contraindications are conditions such as: cataracts, strabismus, labyrinth disorders, macular degeneration, glaucoma, obstructed vision and severe astigmatism. There are many progressive lenses on the market, so every customer should have the one that fits their needs.

How to care for progressive glasses?

First of all, it is worth using dedicated wipes or at least microfiber cloths for cleaning glasses. The lenses can be washed under running water, and at the same time it is worth using a small amount of a neutral pH liquid – the solution should be spread between the fingers to create a foam, which then should be applied to the lenses and finally rinsed with lukewarm water.
