What Are Neurolenses?

Sometimes headaches start with how your eyes line up with each other, and a regular prescription doesn’t always account for that. When your eyes sit slightly out of alignment, your brain has to work all day to keep what you see clear and single. We look at how your eyes team up during comprehensive eye exams, and for some patients, that’s when neurolenses come into the conversation.

Neurolenses are prescription lenses with a gentle, built-in contoured prism, so they can correct your vision and help ease the strain of eye misalignment in 1 pair of glasses. And you won’t have to give up on style, since our opticians can help you fit them into frames you’ll be happy to wear.

How Eye Misalignment Leads to Headaches and Neck Pain

Your eyes are meant to point at the same spot so your brain can blend 2 images into 1. When they’re a little off, the muscles around your eyes keep making tiny corrections to hold everything together. Over a long day, those muscles get tired.

Mild misalignment rarely causes double vision. The signs tend to be more subtle, so watch for a few of these as the day goes on:

  • Headaches that build after reading or screen time
  • Tension in your neck and shoulders
  • Sore, tired eyes
  • Blurry vision after a long stretch with a book or device
  • Dizziness or motion sickness in busy places

You might also tilt your head or lean toward your screen without noticing, which can add to that neck and shoulder tension.

Because these symptoms overlap with tension headaches and even allergies, it’s easy to look everywhere except your eyes. Many people live with binocular vision dysfunction for years before an optometrist links their symptoms to eye alignment.

How Neurolenses Work

Neurolenses use what’s called a contoured prism. The correction changes gradually from the top to the bottom of the lens, so your eyes get support whether you’re looking across the room or down at your phone.

Your eyes turn inward more when you focus up close, so the help they need at your desk can differ from what they need while you’re driving down the highway. Older prism lenses use 1 strength across the whole lens, which can leave some distances with too much or too little correction.

Your fitting starts with a short, painless test on a dedicated device that measures how your eyes align at different distances. Your optometrist pairs those readings with your regular prescription, and the lab makes lenses for your eyes alone. No 2 pairs come out the same, since eye alignment varies so much from person to person.

Who Neurolenses Can Help

Long days on a screen ask a lot of your eyes, and so do long evenings with a good novel. Your optometrist may suggest a neurolens assessment if you:

  • Work at a computer most of the day
  • Study for hours at a time
  • Get headaches when you read
  • Feel queasy in the car or in crowded stores

Give your eyes regular breaks with the 20-20-20 rule while you’re at it. Every 20 minutes, look at something 20 feet away for 20 seconds.

Life out here tends to happen outdoors, and your eyes do plenty of work on a mountain bike trail or a ski run. Steady eye teaming helps you judge depth and follow moving objects, so athletes and weekend adventurers may notice a difference with better-aligned lenses. If winding mountain roads tend to leave you carsick, mention that to your optometrist too.

What to Expect When You Start Wearing Neurolenses

Some people feel a difference within their first few days. Any new prescription comes with an adjustment period, so give your eyes a little time to settle in before you decide how they’re working for you. If your symptoms worsen or something new pops up, call your optometrist.

Neurolenses often aren’t covered by standard vision plans, so check with your insurance provider before your appointment. Your benefits may still apply to frames or other eyewear you buy at the same time.

Some patients compare the price with what they spend on pain relievers and headache remedies over a year, which can help when you’re weighing whether to go ahead.

Getting Started with Neurolenses

Your eyes change over time, and the way they work together can change with them. Regular eye exams can help keep your prescription and alignment needs current.

If you’ve been dealing with headaches or neck tension that keep coming back, bring them up at your next visit. The team at Canmore Family Eyecare would love to help you figure out whether neurolenses make sense for you. Book an appointment, and we’ll start by looking at how your eyes work together.
