What Is Monovision? Understanding How It Works with LASIK and PRK

If you’ve reached your 40s and noticed yourself holding menus, books, or your phone further away to read clearly, you are not alone. Presbyopia is a common age-related condition that nearly everyone develops as they get older. While reading glasses are the most common solution, many patients seeking LASIK or PRK ask about another option: monovision.
At Dishler Laser Institute, one of the most common questions we hear from patients over 40 is whether LASIK or PRK can reduce their dependence on reading glasses. For many individuals, monovision may be an excellent solution.
What Exactly Is Monovision?
Monovision uses a customized vision correction approach that assigns each eye a different purpose, with one eye corrected for distance and the other left uncorrected or corrected for near vision.
💠The dominant eye is utilized for clear distance vision.
💠The non-dominant eye is utilized for intermediate and near vision.
Monovision can be achieved with:
💠LASIK
💠PRK
💠Contact lenses
💠Premium intraocular lenses during cataract surgery
For many patients at Dishler Laser Institute, monovision provides greater visual freedom while significantly reducing the need for reading glasses during everyday activities.
Why Does Monovision Become an Option?
Beginning around age 40 to 45, the eye’s natural crystalline lens gradually loses flexibility. This normal aging process, known as presbyopia makes it increasingly difficult to focus on nearby objects.
Even people who have always had excellent vision eventually experience this change. Presbyopia is not a disease—it is simply a natural part of having more birthdays.
While LASIK and PRK cannot stop the aging process, surgeons can customize these procedures to provide monovision for patients who are good candidates.
How Successful Is Monovision?
Monovision has been studied for decades and continues to be one of the most successful methods for reducing dependence on reading glasses.
Research has found that:
💠Approximately 70% to 80% of patients successfully adapt to monovision after treatment.
💠Carefully selected patients report overall satisfaction rates between 80% and 90%.
Many patients experience a significant reduction in their need for reading glasses when performing everyday tasks such as reading text messages, checking emails, shopping, cooking, or viewing restaurant menus.
Most patients adapt within several days to a few weeks, although full neuroadaptation may take up to a couple months.
At Dishler Laser Institute, our optometrists carefully evaluate each patient’s visual goals, occupation, hobbies, and eye health before recommending monovision. Because not everyone adapts the same way, some patients may first experience monovision with contact lenses to determine whether it is an adequate solution before proceeding with permanent laser vision correction.
How Does Monovision Work with LASIK or PRK?
The LASIK or PRK procedure itself does not change. Instead, the surgeon customizes the laser treatment to create slightly different prescriptions for each eye.
During your consultation at Dishler Laser Institute, our technician will determine which eye is dominant and discuss your daily visual needs.
If monovision is the right option, treatment is designed so that:
💠One eye provides crisp distance vision.
💠The surgeon optimizes the other eye for near and intermediate tasks.
The brain combines the images from both eyes, allowing many patients to comfortably perform activities at multiple distances without constantly reaching for reading glasses.
Is Monovision Right for Everyone?

Although monovision works very well for many people, it is not the ideal solution for everyone.
You may be a good candidate if you:
💠Are over age 40 and experiencing presbyopia.
💠Want greater independence from reading glasses.
💠Have healthy eyes.
💠Understand that no vision correction procedure can guarantee complete freedom from glasses.
Patients whose careers or hobbies require the highest level of depth perception—such as professional pilots or certain competitive athletes—may not be ideal candidates.
That’s why a comprehensive consultation is so important. At Dishler Laser Institute, our surgeon personalize every treatment plan to match each patient’s lifestyle, career, hobbies, and visual expectations.
Will I Still Need Reading Glasses?
One common misconception is that monovision completely eliminates the need for glasses forever.
While many patients rarely use reading glasses for everyday tasks, very small print, prolonged reading, or dim lighting may still require readers.
The goal of monovision is not necessarily to eliminate glasses in every situation but rather to significantly reduce your dependence on them while maintaining excellent functional vision throughout your day.
