Reading glasses are one of the most common eyewear needs in the world — and one of the most misunderstood. Whether you've just noticed you're holding your phone further away to read, or you've been wearing reading glasses for years and want to understand them better, this guide covers everything you need to know about reading glasses in 2026.
Browse our full eyewear collection for premium frames that work beautifully as reading glasses — combining optical quality with designs you'll actually want to wear.
What Are Reading Glasses?
Reading glasses are single-vision lenses with a positive (plus) power that magnify close objects, compensating for the reduced near-focusing ability that comes with age. They're designed for use at close range — typically 30–40cm, the distance at which most people read — and are not suitable for distance vision.
Reading glasses are distinct from prescription glasses in that they're optimised for a single, fixed distance. They're also distinct from progressive or bifocal lenses, which correct both distance and near vision.
Why Do We Need Reading Glasses?
The need for reading glasses is caused by presbyopia — the gradual loss of the eye's ability to focus on close objects that occurs naturally with age. The crystalline lens of the eye, which changes shape to focus at different distances, gradually hardens and loses flexibility over time. This process typically becomes noticeable in the early-to-mid 40s and continues through the 50s and 60s.
Presbyopia is not a disease or a sign of poor eye health — it's a universal aspect of ageing that affects virtually everyone. Reading glasses are the simplest and most effective solution for mild to moderate presbyopia.
Prescription vs Over-the-Counter Reading Glasses
Over-the-Counter Reading Glasses
Ready-made reading glasses are available in pharmacies and supermarkets in standard powers (typically +1.00 to +3.50 in 0.25 increments). They're inexpensive and immediately available, making them a convenient option for those who need occasional reading assistance.
However, over-the-counter reading glasses have significant limitations:
- Both lenses have identical power, which doesn't account for differences between your two eyes
- The optical centres are fixed and may not align with your pupils, causing eye strain
- They're not corrected for astigmatism
- Quality is typically lower than prescription lenses
Prescription Reading Glasses
Prescription reading glasses are made to your exact specifications — the correct power for each eye, optical centres aligned with your pupils, and correction for any astigmatism. They provide significantly better visual clarity and comfort than over-the-counter alternatives, particularly for extended reading sessions.
If you spend significant time reading or doing close work, prescription reading glasses are worth the investment. The improvement in clarity and reduction in eye strain is substantial.
Understanding Reading Glass Strength
Reading glass strength is measured in dioptres, indicated by a plus sign (e.g., +1.50, +2.00, +2.50). Higher numbers indicate stronger magnification. As a general guide:
- +1.00 to +1.50: Mild presbyopia, typically early 40s
- +1.75 to +2.25: Moderate presbyopia, typically mid-to-late 40s
- +2.50 to +3.00: More significant presbyopia, typically 50s
- +3.25 and above: Advanced presbyopia, typically 60s and beyond
These are general guidelines only — an eye examination will determine your exact prescription. Never self-prescribe based on age alone.
Choosing the Right Frames for Reading Glasses
Reading glasses deserve the same attention to frame quality and style as any other eyewear. Since reading glasses are worn for extended periods of focused work, comfort is particularly important.
Lightweight Frames
Lightweight frames reduce fatigue during extended reading sessions. Our Metal Frames collection features premium titanium options that are exceptionally light — ideal for reading glasses worn for hours at a time.
Frame Size and Lens Height
Reading glasses benefit from a moderate to generous lens height, ensuring you have a wide, clear reading zone. Very shallow frames can limit the usable reading area.
Style
Reading glasses are worn in professional and social contexts — they deserve to look as good as they perform. Browse our Clear Frames for modern, understated options, or explore our Best Selling styles for our most trusted designs across all frame types.
Reading Glasses and Screen Use
Standard reading glasses are optimised for approximately 30–40cm — the distance of a book or printed page. Computer screens are typically viewed at 50–70cm, which is a different focal distance. Using standard reading glasses for screen work can cause eye strain because the focal distance doesn't match.
If you use screens extensively, consider computer glasses — single-vision lenses optimised for screen distance — or progressive lenses that provide correction across multiple distances. Discuss your specific needs with your optician.
When to Get an Eye Examination
If you're experiencing difficulty reading or doing close work, an eye examination is the right first step — not a trip to the pharmacy for over-the-counter readers. An eye examination will:
- Confirm that presbyopia is the cause of your symptoms
- Determine your exact prescription for each eye
- Check for other eye health issues that may be contributing to your symptoms
- Advise on the most appropriate lens solution for your lifestyle
Adults over 40 should have an eye examination every one to two years, even without obvious symptoms. Many eye conditions develop gradually and are best caught early.
