Presbyopia vs. Myopia: What’s the Difference?

Vision issues like presbyopia and myopia are among the most common refractive errors in India and everywhere else in the world. Still, their causes and the way they impact daily life are different. Both conditions affect how light is focused in the eye, but they do so in contrasting ways. Understanding the differences between these two vision conditions is essential for managing them effectively and maintaining a clear vision.

What is Myopia?

Myopia, often called nearsightedness, occurs when the eye has a shape that causes light to focus incorrectly. In people with myopia, distant objects appear blurry because the light focuses in front of the retina rather than directly on it. This is often the result of an elongated eyeball or an overly curved cornea.

Nearsightedness can significantly affect daily activities, especially when seeing faraway objects. Understanding the nature of myopia is crucial for choosing the proper treatment approach, which may include corrective lenses or refractive eye surgery such as LASIK.

What is Presbyopia?

Presbyopia is an age-related condition that typically begins in the early to mid-40s. It primarily affects the ability to focus on close objects, making everyday activities like reading or using a smartphone more challenging. Unlike myopia, caused by an irregularly shaped eye, presbyopia results from the gradual hardening of the eye’s lens, reducing its ability to adjust and focus on nearby objects.

This loss of lens flexibility is a natural part of ageing and cannot be entirely prevented. However, early detection and treatment can help individuals manage the condition effectively and maintain their quality of life.

Differences Between Myopia and Presbyopia

While both myopia and presbyopia affect vision, they are caused by different factors and manifest at different stages of life. Let’s look at their major differences!

Aspect	Presbyopia	Myopia
Vision Issue	Difficulty seeing close objects clearly	Difficulty seeing distant objects clearly
Age	Typically begins in the early to mid-40s	Often develops in childhood or adolescence
Physical Changes in the Eye	Loss of elasticity in the lens, making it hard to focus on close objects	Elongation of the eyeball or excessive curvature of the cornea
Common Symptoms	Needing to hold reading material farther away, difficulty reading in low light, eyestrain or headaches from close work	Blurry vision when looking at distant objects, squinting, headaches, eyestrain
Causes	Natural ageing process leading to reduced flexibility of the lens	Genetic factors, environmental influences (e.g. prolonged minute work), lack of outdoor activity
Diagnosis	Comprehensive eye examination that includes testing for reading and close-up vision	Comprehensive eye examination with visual acuity and refraction tests
Treatment Options	Reading glasses, bifocals, progressive lenses, multifocal contact lenses, and refractive surgery in some cases	Prescription glasses, contact lenses, orthokeratology (Ortho-K) lenses, and refractive surgery
Lens	Reading glasses or multifocal progressive lenses designed to compensate for the inability to focus on close objects	Single-vision lenses that correct for distance vision

Corrective Lenses

The most common and straightforward way to correct both myopia and presbyopia is through prescription glasses or contact lenses. Myopia is corrected with concave lenses, while presbyopia is treated with reading glasses, bifocals, or multifocal lenses. Each of these solutions is customised to suit your vision needs and considers the difference between presbyopia and myopia.

Refractive Surgery

For those seeking a long-term solution, refractive surgery is an effective treatment option for both myopia and presbyopia. Refractive procedures reshape the cornea to correct how light is focused in the eye. Presbyopia can also be addressed with corneal inlays or LASIK, which improve the eye’s ability to focus on close objects.

However, any kind of refractive surgery is typically recommended once your vision has stabilised, meaning your prescription has stayed the same for at least one year.

Medicated Eye Drops

Recently, eye drops designed to treat presbyopia have been introduced. These prescription drops work by temporarily constricting the pupils, improving the ability to focus on close-up objects. This treatment is for presbyopia and offers a flexible, non-invasive option for improving near vision. For personalised advice, consult your eye specialist to determine whether eye drops are a suitable option for you.

Can You Prevent Presbyopia and Myopia?

While presbyopia is a natural part of ageing that cannot be avoided, there are ways to reduce the risk or slow the progression of myopia as well as presbyopia.

Preventing Myopia

• Spend more time outdoors: Studies have shown that children who spend more time outdoors are less likely to develop myopia. Natural light and breaks from close-up tasks are beneficial for eye health.
• Limiting screen time: Reducing the amount of time spent on screens or other close-up activities can help slow the progression of myopia, particularly in children.
• Regular breaks: Following the 20-20-20 rule (looking at something 20 feet away for 20 seconds every 20 minutes) can help relieve eye strain and lower the risk of nearsightedness.

Delaying Presbyopia

Though presbyopia cannot be prevented, maintaining overall eye health may help slow its progression.

• Schedule regular eye exams to monitor vision changes.
• Maintain a balanced diet rich in nutrients that promote eye health, such as leafy greens, fish, and fruits.
• Engage in regular physical activity to boost circulation and support eye function.
• Wear sunglasses to protect your eyes from harmful UV rays and safety glasses during risky activities.
• Ensure that you use the correct prescription lenses as your vision changes.

Managing Presbyopia and Myopia

Understanding the differences between presbyopia vs myopia is crucial in choosing the proper treatment and maintaining clear vision. Both conditions are treatable, but they require different corrective approaches.
