Presbyopia
Also known as: Age-related farsightedness, Aging eye
Presbyopia is the gradual loss of your eyes' ability to focus on close objects, and it is a normal part of ageing rather than a disease. The lens inside the eye slowly stiffens over the decades, so it can no longer change shape enough to bring near objects into sharp focus. Most people first notice it in their early to mid-40s, when menus, phone screens, and small print start drifting out of reach. Presbyopia affects everyone eventually, including people who have never needed glasses. It is easily managed with reading glasses, multifocal lenses, or contact lenses, and surgical options exist for those who prefer them.
At a Glance
- Common symptoms
- Holding books, menus, or your phone at arm's length to read, Blurred vision at a normal reading distance, Eye strain or headaches after close work
- Main treatments
- Over-the-counter reading glasses for people who otherwise see well at distance, Prescription bifocal, trifocal, or progressive (varifocal) lenses, Multifocal or monovision contact lenses
- Category
- Eye & Ear · Universal; affects virtually everyone over the age of 45 to some degree
- See a doctor if
- Blurred near vision that interferes with reading or work
Symptoms
Causes
- Hardening of the lens inside the eye with age
- Weakening of the ciliary muscle fibres that reshape the lens for close focus
- Changes in the proteins within the lens that reduce its flexibility
- Normal ageing: no disease or habit causes presbyopia
Risk Factors
- Age over 40: the single biggest factor
- Existing farsightedness (hyperopia), which can make it noticeable earlier
- Diabetes, multiple sclerosis, or cardiovascular disease
- Certain medications, including antihistamines, antidepressants, and diuretics
- Working in jobs that demand a lot of close focus
Diagnosis
- A routine eye examination including a refraction test to measure your focusing ability
- Near-vision reading test with charts at normal reading distance
- Checking eye health to rule out cataracts or other causes of blurred vision
- Discussion of your work, hobbies, and screen use to tailor the correction
Treatment
- Over-the-counter reading glasses for people who otherwise see well at distance
- Prescription bifocal, trifocal, or progressive (varifocal) lenses
- Multifocal or monovision contact lenses
- Prescription eye drops that temporarily constrict the pupil to improve near focus (available in some countries)
- Refractive surgery such as monovision LASIK, or lens replacement surgery
- Supportive: good task lighting, larger font sizes on screens, and regular breaks from close work
Prevention
- Presbyopia cannot be prevented, but regular eye exams keep your correction up to date
- Protect your eyes from UV light with sunglasses
- Manage conditions like diabetes that can affect the lens
- Use good lighting and take breaks during close work to reduce strain
- Eat a diet rich in leafy greens, colourful vegetables, and omega-3 fats for overall eye health
When to See a Doctor
- Blurred near vision that interferes with reading or work
- Headaches or eye strain that don't improve with reading glasses
- Sudden changes in vision, double vision, or flashes of light (these are not presbyopia)
- Any vision loss accompanied by eye pain or redness
