If you’ve ever slipped on your reading glasses behind the wheel to check your dashboard, you may have wondered: Is this safe? The answer is almost always no.

Reading glasses are designed for one thing: making small print clear. They sharpen up menus, books, and your phone screen. But when you’re driving, your eyes need to focus at multiple distances—and that’s exactly where readers fall short.

Why Reading Glasses Blur the Road Ahead

When you’re driving, your eyes are constantly shifting focus between:

• Far distance: Road signs, traffic lights, and oncoming cars
  
  
• Intermediate distance: Dashboard, GPS, or infotainment screen
  
  
• Near distance: Maps, notes, or your phone (when parked, of course)
  
  

Standard reading glasses only optimize near vision, which means your distance vision becomes blurry. That blur could delay spotting hazards, slow your reaction time, and ultimately put you and others at risk.

What Can Go Wrong If You Drive in Readers

Wearing reading glasses on the road can cause:

• Blurred distance vision – Signs look fuzzy until you’re too close
  
  
• Slower reactions – Hazards appear later than they should
  
  
• Reduced awareness – Peripheral vision may feel restricted
  
  
• Eye strain and headaches – Constant refocusing tires out your eyes
  
  

As longtime customer Mary K. put it:
"I made the mistake of driving with my reading glasses once. Everything beyond my dashboard was a blur—never again!"

Driving Vision and the Law

Most DMVs require drivers to meet minimum vision standards:

• Visual acuity: 20/40 or better (with or without corrective lenses)
  
  
• Field of vision: Around 140°
  
  
• Color vision: Ability to recognize traffic signals
  
  

If you drive with the wrong glasses—like readers—you risk:

• Invalidating your driver’s license restrictions
  
  
• Insurance claim issues if an accident occurs
  
  
• Potential traffic violations
  
  

Smarter Eyewear Options for Drivers

If you need reading help but also spend time behind the wheel, consider these better alternatives:

Bifocal Lenses

• Upper lens: sharp distance vision for safe driving
  
  
• Lower lens: clear close-up vision for reading
  
  
• Visible line separating the two zones
  
  

Progressive Lenses

• Seamless correction for distance, intermediate, and near vision
  
  
• No visible lines—more natural, stylish look
  
  
• A favorite among drivers over 40
  
  

Prescription Sunglasses

Perfect for daytime driving, especially when polarized and anti-reflective:

• UV protection for long-term eye health
  
  
• Reduced glare from headlights and shiny roads
  
  
• Better contrast in shifting light
  
  

Tips for Clearer, Safer Driving Vision

• Schedule regular eye exams, especially after 40
  
  
• Keep glasses clean to reduce glare and distortion
  
  
• Adjust car mirrors to minimize blind spots
  
  
• Carry a backup pair of driving glasses in your glove box
  
  
• Ask about anti-reflective coatings for easier night driving
  
  

When to See an Eye Doctor

Book an appointment if you notice:

• Road signs only come into focus at the last second
  
  
• Trouble switching focus between dashboard and road
  
  
• Headaches or eye strain after driving
  
  
• Sudden changes in your vision
  
  

An optometrist can tailor the perfect prescription for driving—often combining distance and reading correction in one pair.

Myth vs. Fact: Driving With Readers

• Myth: Reading glasses are fine for quick glances at the dashboard.
  Fact: Even short use can blur the road ahead, making it unsafe.
  
  
• Myth: You always need separate glasses for reading and driving.
  Fact: Multifocal lenses (bifocals, progressives) handle both seamlessly.
  
  

TL;DR

Reading glasses are great for books—not for the road. Behind the wheel, they blur distance vision and slow reaction times. For safe, comfortable driving, choose bifocals, progressives, or prescription sunglasses designed to cover all distances.

FAQs About Reading Glasses and Driving

Can I drive at night with reading glasses?
No. Night driving requires sharp distance vision, and readers make everything beyond arm’s length blurry.

Do I need separate glasses for driving and reading?
Not necessarily. Progressive or bifocal lenses combine both into one pair.

Will my insurance cover driving glasses?
Car insurance won’t, but vision insurance often does. Check your policy.

How often should I update my driving glasses prescription?
Most experts recommend yearly eye exams to keep your prescription current.
