Progressive eyeglasses have become a popular solution for people who need both near and far vision correction. Unlike bifocals or trifocals, which have visible lines separating different prescriptions, progressive lenses provide a seamless transition between various focal points, offering a more natural visual experience. They allow you to see clearly at all distances, from reading a book up close to focusing on distant objects like a street sign.
While progressive lenses offer convenience and aesthetic appeal, there are hidden dangers associated with them that many people may not be aware of. I want to make you aware of these
pitfalls so you can operate from an informed place and be able to share this with friends and family members who might be using or be considering getting them.
1. Adjustment Period
One of the biggest challenges with progressive lenses is the adjustment period. When you first start wearing them, it can take some time for your brain and eyes to adapt to the new way of seeing. This can lead to discomfort, dizziness, and even headaches. The lenses have multiple focal points (for near, intermediate, and distance vision), which means your eyes have to constantly adjust as you shift your gaze.
For some people, the transition can be difficult and cause temporary problems like nausea, eye strain, and blurred vision, especially if they are new to wearing any form of prescription eyewear. The discomfort might subside with time, but it’s not guaranteed for everyone.
2. Peripheral Distortion
Progressive lenses operate by having areas of the lens dedicated to different vision ranges, but the edges of the lens are often not as clear as the center. This is especially true for the areas that provide intermediate and near vision. The edges of the lenses tend to have distortions, which can make objects appear out of focus or blurry.
For some wearers, this distortion can be problematic, especially when turning your head or looking out of the corner of your eyes. For example, you might not notice an obstacle while walking or driving if you’re looking out of the periphery. This could result in accidents or even falls, particularly for older individuals who rely heavily on their vision.
3. Increased Risk for Older Adults
Older adults who require progressive lenses may be even more vulnerable to the hidden dangers from progressive lenses. The problem is as we age our depth perception and balance tend to decline, making us more prone to falls or accidents. Progressive lenses, with their peripheral distortions and the need for constant eye adjustment, can complicate this issue.
There’s been research looking at this and they found that older folks who wear progressive lens were almost twice as likely to fall verse people wearing single-vision lenses.
A compilation of studies in the Journal of Refractive Surgery found that people were three times more likely to trip and fall outside the house.
Moreover, some elderly individuals may already have difficulty with spatial awareness, and the use of progressive lenses could further impair their ability to judge distances accurately. This is especially true when the person is driving, walking on uneven surfaces, and especially when using the stairs.
When we walk without glasses, we see the ground about 5 or 6 feet in front of you. With progressive lens you only see a little more than a foot in front of you. This means you could miss stairs and obstacles outside.
One ophthalmologist pointed out that professionals in the field may not be aware of this problem because when someone falls, they go to the hospital and not to their optometrist or ophthalmologist. As a matter of fact, 23 states have no requirement that opticians have education and training to be licensed.
4. Difficulty with Certain Activities
While progressive lenses are great for general everyday activities, they may not be ideal for specialized tasks that require very precise vision, such as reading fine print or engaging in hobbies like knitting or sewing. The lower portion of the progressive lens is designed for near vision, but it might not provide enough clarity for very detailed tasks. If you’re an avid reader or need sharp vision for intricate work, you may find the limitations of progressive lenses frustrating.
Additionally, activities like using a smartphone, working on a computer, or driving at night can be challenging. For example, progressive lenses can cause glare or difficulty focusing on small screens. Some wearers report feeling more fatigued after long periods of digital screen use because of the constant shifting of their focal points.
5. Potential for Incorrect Prescription
Not all progressive lenses are created equal, and it’s essential to ensure that your prescription is accurate. An improper fit or poorly made lenses can exacerbate the issues discussed above, leading to even more discomfort or vision problems. If your lenses are not calibrated to your specific needs, you may find yourself with blurred vision, headaches, or even eye strain that could cause long-term damage.
If your optometrist doesn’t take proper measurements or if you choose low-cost lenses from less reputable brands, you may be setting yourself up for a frustrating experience.
6. Compromised Peripheral Vision
In addition to distortion at the edges of the lenses, progressive glasses can also compromise your peripheral vision. The side areas of the lens, designed for near vision, can be hard to navigate without awkward head tilting. The wider your field of vision, the more pronounced the peripheral limitations may feel. This could affect activities like walking in crowded spaces or driving in traffic, where a wide and clear field of vision is critical.
7. Cost and Maintenance
Progressive lenses tend to be more expensive than regular single-vision lenses or bifocals. While they offer convenience, the higher cost could lead some users to settle for lower-quality products or lens options that don't fully address their visual needs. Additionally, progressive lenses often require specialized care and adjustments, meaning you may need to visit your optometrist more frequently for tweaks or repairs.
Conclusion: Are Progressive Glasses Right for You?
Progressive eyeglasses can certainly improve quality of life for many people by providing a more seamless transition between different focal points. However, it’s important to be aware of the potential dangers and challenges they present. From adjustment difficulties to peripheral distortions and increased risks for older adults, these lenses aren’t always the perfect solution for everyone.
One option would be to get a pair of single focus lens to use when you go for a walk or driving your car.
So…to progressives or not, that is your question!
