Progressive lenses are specially designed eyeglasses that allow the wearer to see clearly at far, intermediate, and near distances without the visible lines of traditional bifocal and trifocals. They’re a popular choice due to their modern look and designs that allow a wide range of everyday activities, from reading and computer use, to driving and other distance-focus activities.  

The latest custom and free-form progressive designs now allow optimization of specific viewing areas to the unique visual needs of each wearer.   

What Are Progressive Lenses?  

In simple terms, there are three primary viewing zones in progressive lens designs. They include:  

• Top: Distance vision (seeing far away)  
• Middle: Intermediate vision (computer and arm’s-length tasks)  
• Bottom: Near vision (reading and close-up work)  

The zones blend smoothly into one another. This requires very precise design calculations (to the 100th of a millimeter in advanced designs) while creating and fitting the lenses into the desired frame. That’s why even a tiny error while measuring, generating or fitting can disrupt the vision throughout the entire lens, potentially creating an unwelcome outcome.  

Today’s progressive lens designs are far more complex than those offered just a few years ago, requiring extensive knowledge and understanding to properly select, measure, generate, and fit them to the needs of the wearer. Even a small error during any of these steps can compromise the visual comfort and performance of the lenses. Allow me to explain!  

Common Errors In Lens Fitting  

Here are a few of the mistakes that happen during the lens-making process:  

1. Incorrect/missing fitting measurements – Improperly locating the lens power within the frame, and failure to confirm proper fitting of the glasses at delivery. These are THE MOST OFTEN reported errors.  
2. Wrong lens power – Prescription powers in error, or lenses that do not match the written prescription.  
3. Lens defects – Pits, scratches, and waves created during grinding, polishing, or coating. 
4. Incorrect lens material or coating – Using the wrong lens material or coating for the need. 
5. Lens-to-Frame errors – Lenses that don’t properly fit the frame. Too small and they fall out, too large and it creates pressure points and distorts vision.  

How These Errors Affect the Wearer  

When something goes awry during the process, the person wearing the glasses may notice it right away. Common problems include:  

• Blurry vision- at all or just certain distances  
• Headaches- from eye strain  
• Dizziness- or an off-balance feeling  
• Nausea- especially while walking or with rapid head movement 
• Eye Fatigue- Tired, burning sensation after relatively short use  
• Time to “adjust”- that never really goes away  

These issues don’t just affect comfort; they can affect safety as well. Blurry vision while walking down stairs or when driving can be dangerous.  

How to Avoid Problems  

Dealing with a reputable eyewear provider is the easiest way. Most errors in progressive lenses in Lansing can be avoided by having your prescription filled by a knowledgeable professional. One that:  

• Helps select the appropriate frame. One equally suited to the wearer, the prescription, and the need, not just the latest fad.  
• Uses the latest free-form progressive designs, to ensure the highest quality vision  
• Takes all the requisite fitting values during the order. Up to 14 or more 
• Enforces strict quality standards at each stage of the process  
• Uses Certified Opticians, who understand progressive lens designs  
• Inspects the final product before delivery to the wearer  

When your eyecare professional follows these steps carefully, the final product performs the way it was intended.  

What Should Wearers Do If Something Feels Wrong  

If your new progressive lenses feel a little off, don’t just accept the discomfort.  

• Give it some time- It is normal for it to take a few minutes to a few days for your brain to become accustomed to a new prescription for progressive lenses. Longer than a week may signal a problem. See to your Optician. 

• Note what seems ‘wrong’- Is the vision blurry at all distances or a certain distance? Does it happen only when walking, reading, or all the time?  

• Return to your eyecare provider. Your Goodrich Optical certified optician in Lansing will re-check and confirm the prescription, fitting measurements and adjustment of the glasses 👓 against the original prescription. If an error is found, they will remake the lenses at no charge. 

• Consider Your Options. If you find you simply cannot adjust to your new progressive lenses, Goodrich Optical will replace them with; a different progressive design, single vision lenses, bifocals or trifocals, at no extra cost unless you upgrade to a more costly progressive design or include additional options. But there are timelines. Usually 60-90 days.

FAQs  

Q1). How long does it normally take to adjust to progressive lenses?

A few minutes to a few days is enough for most people to adjust. Any longer may signal a problem.

Q2). Can a manufacturing error in progressive lenses be fixed, or do I need new glasses?

In most cases, the lenses will be remade rather than replacing the whole pair of glasses. The frame can be reused.  

Q3). How can I tell if my discomfort is from an error or just from getting used to progressives?

Normal adjustment typically improves or becomes less annoying each day. The symptoms of an error tend to remain or get worse.
