Single vision lenses contain one prescription power across the lens for one main viewing range. They can be prescribed for distance vision, near tasks such as reading, or an intermediate working distance such as a computer screen. They are commonly used to correct refractive errors including myopia, hyperopia and astigmatism.
The right single vision lens depends on more than the prescription alone. Frame size, lens material, working distance, coatings and how the glasses will be used can all affect comfort, thickness and cost. An eye examination is needed to determine the prescription and whether single vision lenses are appropriate for your needs.
Key Takeaways
- Single vision lenses have one prescription power for one main viewing distance.
- They can be made for distance, reading or intermediate/computer use.
- They can correct myopia, hyperopia and astigmatism when prescribed appropriately.
- High-index materials can reduce thickness in stronger prescriptions but do not automatically provide sharper vision.
- Anti-reflective coatings can reduce reflections from the lens surfaces, but they do not remove every type of glare.
- Blue-light filtering lenses should not be treated as a proven treatment for digital eye strain.
- Australian-made status describes manufacturing origin; it does not automatically mean a lens is optically superior.

Find an OptometristWhat Are Single Vision Lenses?
Single vision spectacle lenses are designed with one main optical prescription across the lens. Unlike progressive or other multifocal lenses, they do not contain separate distance, intermediate and near zones within the same lens.
A single vision prescription can still include sphere, cylinder and axis values to correct refractive error and astigmatism. The term ‘single vision’ describes the lens design, not the strength or complexity of the prescription.
Distance, Reading and Computer Single Vision Lenses
| Lens type | Main use | Important note |
|---|---|---|
| Distance single vision | Driving, television, sport and general distance tasks | Near tasks may still require a separate correction, especially with presbyopia. |
| Reading single vision | Books, phones and other close work | The prescription is chosen for a near working distance. |
| Intermediate / computer single vision | Desktop monitors or another specific working distance | The prescription should match the actual screen or task distance rather than a universal measurement. |
The correct working distance varies between people and tasks. A desktop monitor, laptop and handheld phone are often used at different distances, so one near prescription does not necessarily suit every activity.
Which Vision Problems Can Single Vision Lenses Correct?
Myopia (short-sightedness)
Myopia makes distant objects appear blurred because light focuses in front of the retina rather than directly on it. Prescription glasses can correct the blur by changing how light is focused. Read AMV’s guide to myopia for symptoms, assessment and management information.
Hyperopia (long-sightedness)
Hyperopia can make close objects difficult to focus on and may also affect distance vision depending on the prescription, age and focusing ability. Healthdirect notes that glasses can be used to correct long-sightedness.
Astigmatism
Astigmatism occurs when the cornea or natural lens has different curvature in different directions. It can cause blurred vision at more than one distance and may be corrected with prescription glasses, contact lenses or other options depending on the individual.
Presbyopia and reading glasses
Presbyopia is the age-related loss of near focusing ability that usually becomes noticeable from around age 40. Some people use single vision reading glasses, while others prefer multifocal or progressive lenses so they do not need to change glasses for different distances.
Single Vision vs Multifocal and Progressive Lenses
| Feature | Single vision | Progressive / multifocal |
|---|---|---|
| Prescription zones | One main power | More than one viewing zone |
| Typical use | Distance, reading or a defined working distance | Distance, intermediate and near in one pair |
| Field of view | Wide field for the chosen distance | Usable zones vary by design and prescription |
| Glasses changes | May require separate pairs for different tasks | Can reduce the need to switch pairs |
| Fitting | Depends on prescription and frame | Requires accurate fitting for the selected multifocal design |
Neither design is automatically better. The most useful option depends on your prescription, age, tasks, preference for one or multiple pairs, and how you adapt to different lens designs.

Find an OptometristChoosing a Lens Material
Lens material affects thickness, weight, impact resistance, optical characteristics and price. A stronger prescription does not automatically mean you need the highest available refractive index.
Standard and high-index materials
Higher-index materials bend light more efficiently, so they can reduce the thickness of stronger prescriptions. The amount of visible thinning depends on the full prescription, frame size and shape, lens design and where the eyes sit in the frame. Read AMV’s high-index lens guide before assuming a higher index is automatically worth the extra cost.
Impact-resistant materials
Some lens materials are selected when impact resistance is especially important, such as certain children’s eyewear, sports or safety applications. Material choice should be based on the prescription, frame, relevant safety standard and intended use rather than a blanket rule that one material is ‘virtually unbreakable’.
Do You Need Anti-Reflective or Other Coatings?
Anti-reflective coatings reduce reflections created by the spectacle lens surfaces. They can make reflections less distracting and may be useful with some high-index materials. They do not remove all glare from headlights, wet roads, low sun or other bright sources. Read AMV’s anti-reflective coating guide for benefits, limitations and care.
Scratch-resistant and easy-clean coatings
Some coatings are designed to improve resistance to everyday scratches or make water, oils and fingerprints easier to clean. Performance and warranties vary between products, so ask what is included rather than assuming every coating package provides the same protection.
Photochromic options
Single vision prescriptions can often be combined with photochromic technology, which darkens in response to particular light conditions. Compare photochromic lens benefits and limits if you are considering one pair for indoor and outdoor use.
What About Blue-Light Filtering?
Blue-light filtering should not be presented as an essential addition to single vision lenses. A 2023 Cochrane review found that blue-light filtering spectacle lenses may not reduce short-term eye strain from computer use compared with non-filtering lenses, and evidence for sleep-related benefits remains uncertain.
If screen discomfort is your main concern, read AMV’s Blue Light Glasses guide and consider whether prescription, dry eye, working distance, breaks or workstation setup may be more relevant.
Australian-Made Single Vision Lenses
Some prescription spectacle lenses are manufactured in Australia, and some specific products are licensed to carry the Australian Made logo. If local manufacturing matters to you, ask the practice which exact product is being supplied and what part of the manufacturing process occurs in Australia.
The Australian Made logo is a registered certification trademark and can only be used on licensed products that meet the applicable country-of-origin rules. Australian-made status does not automatically prove that a lens has better clarity, wider vision, faster delivery, greater durability or a lower environmental impact than an imported lens.
Stock Lenses vs Surfaced-to-Order Lenses
A stock lens is a pre-manufactured lens available in common prescription powers. A surfaced-to-order lens is produced or finished for a specific prescription and order. Both can be appropriate depending on the prescription, lens design, frame and product range.
It is not accurate to say that stock lenses are inherently low quality or that a surfaced lens automatically provides wider peripheral vision. Ask which lens design is being recommended and what practical benefit it offers for your prescription.
Can You Put New Single Vision Lenses Into an Existing Frame?
Often, yes. Re-lensing an existing frame may be possible if the frame is in suitable condition and can be safely handled during lens fitting. There is no universal rule that a frame must be less than three years old. The practice should inspect the frame for wear, damage, brittleness, loose joints or other problems before accepting it.
What About Ready-Made Reading Glasses?
Ready-made readers use the same plus power in both lenses and are designed as a general near-vision option. They do not account for differences between the two eyes, astigmatism or an individual prescription.
They may suit some people with uncomplicated presbyopia for occasional near tasks, but recurring headaches, blur, double vision or unequal vision between the eyes should be professionally assessed rather than blamed on the readers alone.
How Much Do Single Vision Lenses Cost in Australia?
There is no reliable single Australia-wide price range because practices package lenses, frames, materials, coatings and services differently. A basic stock single vision lens may cost less than a high-index, coated or surfaced-to-order lens, but the final amount depends on the prescription and provider.
For a meaningful comparison, ask for an itemised quote showing the lens material, any coatings, the frame price, fitting or dispensing services, and any remake or warranty terms.
Questions to Ask Before Ordering Single Vision Lenses
- Are these lenses for distance, reading or a specific intermediate working distance?
- Which lens material are you recommending, and why?
- Would a higher-index material make a meaningful difference in this frame?
- Which coatings are included and which are optional?
- Is this a stock lens or a surfaced-to-order lens, and does that matter for my prescription?
- If the lens is described as Australian made, can the specific product claim be verified?
- What warranty, adjustment or remake policy applies?
- Can my existing frame be safely re-lensed?

Find an OptometristFrequently Asked Questions
Can single vision lenses correct astigmatism?
Yes. A single vision prescription can include cylinder and axis values to correct astigmatism. The exact prescription is determined during an eye examination.
What is the difference between single vision and multifocal lenses?
Single vision lenses use one main prescription power for one viewing range. Multifocal and progressive lenses contain more than one viewing zone so one pair can support different distances.
Do I need separate reading and distance glasses?
Sometimes. Some people prefer separate single vision pairs because each gives a wide field for one task, while others prefer multifocals or progressives for convenience. The best choice depends on your prescription and daily activities.
Are high-index single vision lenses always worth the extra cost?
No. Higher-index materials can reduce thickness in stronger prescriptions, but the practical benefit depends on prescription strength, frame size and shape, material trade-offs and price.
How long do Australian-made single vision lenses take to arrive?
There is no universal turnaround time. It varies by manufacturer, prescription, material, coating, practice and current workload. Confirm the expected delivery time for the specific lens being ordered.
Can new single vision lenses be fitted into my old frames?
Often, yes, if the frame is structurally sound and suitable for re-lensing. The practice should inspect the frame before accepting the job.
Are ready-made pharmacy readers the same as prescription single vision reading glasses?
No. Ready-made readers generally use the same plus power in both lenses and do not correct astigmatism or differences between the eyes. Prescription reading glasses can be tailored to the individual prescription.
Do blue-light filters make single vision lenses better for computer work?
Not necessarily. Current evidence does not show a clear short-term eye-strain benefit from blue-light filtering lenses compared with non-filtering lenses. The correct prescription, working distance and screen habits may be more important.
