Bifocal Reading Glasses vs. Adjustable Focus: Which Are Right for You?

Bifocal Reading Glasses vs. Adjustable Focus: Which Are Right for You?

Whether you’re new to wearing glasses, have always needed glasses for nearsightedness, or simply need a new pair of specs, finding the right fit can be a daunting task. Perhaps you are tired of carrying around multiple pairs of readers. Maybe you’ve had bifocal readers in the past, but you (or your eyes) are not a big fan of constantly jumping back and forth, from one strength to another. Maybe your bifocals no longer work for all your daily activities.

Bifocals can be problematic for many wearers, and as a result, many are moving away from the bifocal style to a more comfortable, versatile fit: adjustable focus readers. But what is the difference between these two types of reading glasses, and which is the perfect pair for you? Here, we will discuss bifocal reading glasses, Adlens’ UZOOM Precision readers, and why the latter, adjustable vision glasses may be a more fitting choice for you.

What are Bifocal Reading Glasses?

Bifocals are glasses that have two distinct optical powers. The top half of the lens works to correct distance vision, while the bottom half serves to correct near-distance vision, mainly for reading. The first pair of bifocal reading glasses was invented by Benjamin Franklin.

Before the start of the 20th century, two separate lenses were cut in half and combined in the rim of the frame to create bifocals. But this method led to a number of early complications and made the glasses very fragile. Today, most bifocals are created by molding a segment for reading into a primary lens. These are available with the reading segments in a variety of shapes and sizes. The most popular of bifocal reading glasses is the D-segment, 28 mm wide. While the D-segment bifocals are beneficial, more and more people are now choosing adjustable focus readers, so that they can have even more control over their reading power.

Who Do They Benefit?

Bifocal reading glasses are commonly prescribed to people with presbyopia, a condition that affects our ability to focus clearly at different distances as we age. Benjamin Franklin, like many adults over 45 today, suffered from presbyopia himself. In August 1784, Franklin wrote to his friend George Whatley, “[I] am happy in the invention of double spectacles, which serving for distant objects as well as near ones, make my eyes as useful to me as ever they were.” In addition to presbyopia, bifocals are also commonly used to treat myopia, hyperopia, and/or astigmatism.

Pros & Cons of Bifocal Readers

Bifocals help many people who struggle with both nearsightedness and farsightedness. With bifocals, you can swap out two pairs of readers for one. But bifocal reading glasses can also cause some health concerns, such as headaches and even dizziness in users. Adjusting to the small field of view for the reading portion of the lenses can take time, as a person learns to move the head or the reading material, rather than the eyes. Looking at a computer monitor can lead to muscle fatigue, due to the unusual straight and constant movement of the head. Undoubtedly, there is an adjustment period with bifocals.

It is important to note that bifocal reading glasses also only have diopters for far vision and close vision, but no lens for intermediary distances. If you have trouble seeing things that are not near nor far, such as the computer, you may need a more versatile lens.

Adjustable Focus Reading Glasses

Adjustable, magnifying reading glasses such as UZOOM Precision can serve as a remedy for these bifocal challenges. Adjustable focus readers serve as a great alternative to bifocal reading glasses, breaking people free from the restricted, limited views that too often come with bifocals.

Like bifocal reading glasses, adjustable focus readers allow you to see at different distances. Only with UZOOM Precision, you can control the strength of your lenses and easily transition anywhere between +0.5 and +4.0 diopters.

Unlike other adjustable focus readers, UZOOM Precision offers pin-sharp focus, helping users with daily up-close tasks, honing-in on fine details, and carrying out a variety of hobbies. This is particularly helpful for the many people today who are spending more time in front of computers or tablets. For those long hours in the office – the adjustable focus lenses offer comfortable and clear vision. But it’s not just for your 9 to 5. Whether you enjoy reading, knitting, sewing, scrapbooking, even wood carving – adjustable focus readers can help with any of your daily activities! Other perks of adjustable focus readers include:

  • A 2.8x magnifying boost for detail work
  • You can focus clearly from 9 inches to 6 feet away
  • UZOOM works whatever your current reader power
