Managing Presbyopia and Astigmatism: Causes, Symptoms, and Treatment Solutions
Explore effective strategies for diagnosing and treating presbyopia and astigmatism, including glasses, contacts, and eye surgery.
How to Manage Presbyopia When You Have Astigmatism
Presbyopia and astigmatism are two frequent but distinct eye conditions that can significantly affect your visual quality and daily living. While presbyopia is an age-related change in your eye’s lens, astigmatism arises from improper curvature of the cornea or lens. Many adults experience both conditions, resulting in compounded difficulty with clear vision both up close and at a distance. This guide covers their causes, symptoms, and a range of treatment options to optimize your eye health and visual comfort.

About Astigmatism
Astigmatism is a common refractive error affecting vision at any age. It is caused by an irregular curvature of either the cornea (the transparent front layer of the eye) or the crystalline lens. Instead of having a perfectly round shape, the surface is more oval, like a football. This irregularity prevents light from focusing evenly onto the retina, resulting in blurred or distorted vision at all distances.
Causes of Astigmatism
- Irregular corneal curvature
- Irregular lens curvature
- Genetics (often present from birth)
- Eye injury or surgery may alter eye shape
Symptoms of Astigmatism
- Blurry or distorted vision
- Eye strain
- Headaches
- Difficulty seeing clearly at night
- Squinting
Diagnosis of Astigmatism
An eye exam with an optometrist or ophthalmologist will detect astigmatism. Instruments like phoropters and keratometers help measure the degree and axis of astigmatism. Early diagnosis helps prevent complications and enables the right corrective strategy.
About Presbyopia
Presbyopia refers to the gradual loss of your eye’s ability to focus on nearby objects. This age-related change usually begins to affect adults after age 40. Unlike astigmatism, which is tied to the shape of the eye, presbyopia is linked to the lens losing flexibility due to the natural aging process.
Causes of Presbyopia
- Loss of lens flexibility (aging)
- Slower accommodation between near and distant objects
- Not influenced by eye shape, but by changes in lens proteins over time

Symptoms of Presbyopia
- Difficulty reading small print or seeing objects up close
- Need to hold reading materials further away
- Eye strain or headaches after close-up tasks
- Blurred near vision, while distance vision remains clearer
- Need for brighter lighting during reading or close work
- Squinting to read
Diagnosis of Presbyopia
Presbyopia is usually diagnosed based on patient-reported symptoms and a routine vision test at an eye clinic. It is considered a natural part of the aging process, and virtually all people will experience it at some point after the age of 40.
Can You Have Both Presbyopia and Astigmatism?
It is entirely possible to have both presbyopia and astigmatism at the same time. Because the two conditions have different causes—one due to lens aging, the other due to corneal or lens curvature abnormalities—their onset and progression are independent. Many adults deal with both simultaneously, compounding challenges for clear vision both up close and at a distance. This overlap may require specialized correction to address both problems effectively.
How Do You Treat Presbyopia and Astigmatism Together?
Treatment approaches depend on the degree and stage of each condition. Some mild cases can be managed without clinical intervention via lifestyle adaptations, while more pronounced vision problems will likely require prescription solutions or surgery. The optimal strategy should be personalized by an eye care professional.
Managing Mild Presbyopia and Astigmatism
- Use larger print materials
- Increase ambient lighting
- Adjust reading habits (hold materials farther away)
- Monitor vision changes regularly with eye exams
Prescription Glasses
With both presbyopia and astigmatism, most people benefit from prescription glasses that correct both simultaneously. Specialized lenses, such as bifocals or progressive lenses, can address presbyopia, while toric lenses correct for astigmatism. Your eye doctor will determine the right combination for your needs.
- Toric lenses: designed to correct astigmatism’s irregular focus
- Progressive or bifocal lenses: allow clear focus on both near and far objects for presbyopia
- Single pair of glasses can be customized to address both conditions together
Contact Lenses
Contacts are another suitable option for managing both issues. For presbyopia, multifocal contact lenses are available, providing varying lens powers for distance and near correction. For astigmatism, toric contact lenses are designed to address the uneven curvature of the cornea. These can be combined:
- Toric multifocal lenses: correct both presbyopia and astigmatism in a single lens
- Monovision technique: one eye fitted for near vision, the other for distance, sometimes with toric correction as needed
- Rigid Gas Permeable (RGP) lenses: often beneficial for more severe astigmatism due to their structured design
Consultation with an optometrist or ophthalmologist is necessary to determine the most effective contact lens strategy. Individuals with complex prescriptions may need custom-lens fitting and ongoing monitoring.
Surgical Options
If non-invasive corrections do not yield satisfactory results, several eye surgeries can address either or both conditions:
- LASIK surgery: reshapes the cornea to correct astigmatism and can incorporate techniques to aid presbyopia (e.g., PresbyLASIK)
- PRK (Photorefractive Keratectomy): an alternative to LASIK, effective for suitable candidates
- Lens replacement surgery (Refractive Lens Exchange, RLE): replaces the natural lens with an artificial one, targeting presbyopia and astigmatism simultaneously
Surgical suitability depends on your overall eye health, age, lifestyle needs, and the severity of your visual impairment. Not every surgery will be appropriate for every individual—discussion with a surgeon is essential for risk evaluation and expected outcomes.
Combination Treatments
Sometimes a combination of approaches yields the best results. For example, you might use prescription glasses for day-to-day activities and eye drops (where indicated) to help with presbyopia, or combine glasses with contacts for specific tasks or environments.
- Mix and match: Prescription glasses and contacts, or glasses with surgical correction
- Customized treatment plans: Your optometrist or ophthalmologist tailors solutions to your unique needs and daily routines
- Periodic reassessment: Ongoing examination to track progress and adjust treatment as conditions evolve
Lifestyle Considerations for Dual Eye Conditions
Living with both presbyopia and astigmatism may require some practical lifestyle adaptations:
- Optimize home and work lighting conditions to reduce eye strain
- Use digital devices with adjustable font sizes
- Plan regular eye checkups to update prescriptions as required
- Consider backup solutions (e.g., reading glasses in addition to contacts)
Preventative Tips and Outlook
While neither presbyopia nor astigmatism can be prevented due to their biological roots, early detection through routine vision exams and prompt correction can keep your eyes healthy and mitigate symptoms:
- Schedule annual eye exams after age 40
- Use prescription glasses or contacts as recommended
- Follow practitioner guidelines on surgery and postoperative care
- Adopt healthy lifestyle choices (diet, UV protection, avoiding smoking)
The outlook is positive for individuals who seek timely correction. The majority of people enjoy improved quality of life and vision when both conditions are properly managed.

| Prognosis | Requires updated correction over time | Stable with proper correction |
Frequently Asked Questions (FAQs)
Q: Can you develop presbyopia and astigmatism simultaneously?
A: Yes, both can coexist because presbyopia stems from lens aging, while astigmatism results from corneal or lens shape irregularities. Their overlap is common after age 40.
Q: Which type of glasses are best for both conditions?
A: Bifocal or progressive lenses combined with toric features can address presbyopia and astigmatism together. An eye care professional can customize the optimal prescription.
Q: Are there contacts that treat both presbyopia and astigmatism?
A: Yes. Toric multifocal contact lenses can correct both issues, and the monovision approach may be used for specific cases.
Q: Does either condition lead to blindness?
A: Neither presbyopia nor astigmatism causes blindness. Both are refractive errors that can be managed with appropriate correction. Untreated, symptoms may worsen, but they do not harm overall eye health.
Q: What is monovision?
A: Monovision is a contact lens correction strategy where one eye is fitted for near vision and the other for distance. This is sometimes suitable for people with astigmatism in both eyes and presbyopia.
Takeaway
You do not have to struggle with the compounded challenges of presbyopia and astigmatism. Modern eye care offers diverse, effective treatments—from custom glasses and multifocal contacts to advanced surgeries—that can restore clarity and comfort to your vision. Regular visits to your eye specialist are essential to ensure that your correction remains optimal as both conditions evolve. Asking questions and staying informed helps you preserve your eye health and enjoy all aspects of daily life.
