Progressive lenses

What are they?

 

Progressive lenses basically have three prescriptions in one pair of glasses. That allows you to do close-up work (like reading a book), middle-distance work (like checking out a website on a computer), or distance viewing (like driving) without needing to change your glasses. Progressive lenses are no-line multifocal eyeglass lenses that look exactly the same as single vision lenses. In other words, progressive lenses will help you see clearly at all distances without those annoying (and age-defining) „bifocal lines“ that are visible in regular bifocals and trifocals.

 

 

Who uses progressive lenses?

Progressive lenses are the lens of choice for practically anyone who needs corrective lenses to see distant objects clearly (due to farsightednes­s and/or astig­matism) and has also become presbyopic.

Presbyopia is a condition when your vision blurs when you're doing close-up work like reading or sewing. Don't worry, it's a natural part of getting older.

Advantages of progressive lenses

 

One of their instant advantages is that the design of progressive lenses blends the prescription. There is no image jump or visible line on the lens. This enhances your comfort with your lenses and is a safer option when doing things such as driving.

That’s not to mention that more lenses and frames mean more maintenance and more money. That is just not as convenient. With progressive lenses, you don’t have to take them off when switching between things such as working on a computer and driving.

Even if you don’t use a computer, anything with an LCD or LED screen can be damaging to your eyes. So, you want that intermediate correction. Progressive lenses can correct distance, intermediate and reading focus with one lens. It’s like killing three birds with one stone.

Disadvantages of progressive lenses

 

One of the few progressive lens disadvantages it that there are occasionally problems with high definition progressive lenses when walking up and downstairs. Since the reading correction is at the bottom, the stairs may seem like they bounce and appear wobbly. However, it’s all about adapting to your progressive lenses. With progressive lenses, problem often disappears in about two weeks, so it’s important to give it time if you've just started to wear them.

You may also have an issue with the materials, coatings, adjustments, and position-of-wear, rather than with the progressive lens itself. Some people also feel like they just don’t like progressive lenses and that they’re too hard to get used to. Progressive lenses aren’t for everyone. A small percentage of people are unable to adapt to them, and in these cases, bifocals are a better alternative.

 

 

Conclusion

 

Progressive lenses let multiple vision fields to be added to a single lens, and progressively adjust for the distance of the object we are lookin at. With almost no disadvantages, other than the time used for your eyes to adapt, they are a no-brainer choice for anyone with presbyopia. You can also look at it this way: It's like having three sets of lenses in one, all without ever having to change your eyeglasses.
