Single-Vision Lenses

Single-vision lens European manufacturing 3-year warranty
Registered optician-optometrists
Single-vision lenses are prescription lenses that correct a single viewing distance. They are the most common in prescription glasses and are used to correct myopia, hyperopia, astigmatism or presbyopia. Unlike progressive lenses, they have a single prescription across the entire lens. That is why they are usually more affordable, easy to adapt to and very comfortable for those who only need to correct one distance.

What they are

What are single-vision lenses?

If you wear glasses to see far, near or to drive, single-vision lenses are your solution: one focal point and maximum sharpness for the activity you need most. And when your prescription changes or they get scratched, there's no need to change the frame.

We make your single-vision lenses in leading labs with the same materials and processes as the big high-street opticians, but without their overheads: high-quality prescription lenses at a price up to 80% lower. If you spend many hours on screens, office lenses are an alternative; and if you also have presbyopia, try progressive lenses.

Distance vision

Driving, walking, watching TV or using your glasses daily with sharp vision.

Near vision

Reading, looking at your phone, sewing or any precision task without straining your eyes.

Intermediate distance

Working at the computer or in office settings at the perfect distance.

When to replace

When should you replace the lenses?

If the frame is still fine but the lenses no longer offer comfortable, clear or safe vision, it's time to renew them.

  • The lenses are scratched
  • You see blurry or strain your eyes
  • Your prescription has changed
  • You get headaches when wearing the glasses
  • The anti-reflective coating is peeling or cracking
  • Glare bothers you when driving at night
  • You want to add a blue-light filter for screens
  • You want to turn them into prescription sunglasses
  • You want thinner, more aesthetic lenses
Price

Price of replacing single-vision lenses

The replacement starts from 30 €. The final price depends on your prescription, the index, the frame and the treatments you choose.

FactorHow it affects the price
PrescriptionHigh prescriptions may need thinner lenses.
Thinning indexThe higher the index, the thinner and more aesthetic the lens.
Frame typeRimless, semi-rimless or curved frames require more technical work.
TreatmentsAnti-reflective, blue-light filter, photochromic, hardening or UV can change the price.
Lens typeA basic clear lens doesn't cost the same as a sun, polarised or photochromic one.

If your prescription or frame needs a special solution, we'll contact you before continuing.

Unsure about the index?

If you have a high prescription or aren't sure, ask us before ordering and we'll help you choose.

Thinning index

Which thinning index do I need?

The index determines the lens thickness: the higher the index, the thinner the lens.

1.67High prescriptionsThinner, more aesthetic lens.

Treatments

Treatments for your single-vision lenses

Personalise your lenses according to how you'll use them. You can combine several treatments.

Anti-reflective Included

Reduces glare from lights, headlights, screens and shop windows. Clearer, more comfortable vision; ideal for night driving.

Hardened / anti-scratch Included

Improves surface resistance to daily wear and extends the lens's lifespan.

Blue-light filter

Designed for many hours at the computer, phone or LED screens. Improves visual comfort in digital environments.

Photochromic

Darkens in sunlight and clears indoors. A single pair for inside and outside.

UV protection

Protects your eyes from UV radiation, even in clear lenses. Recommended for daily use.

Water-repellent and anti-smudge

Repels water, grease and dust, makes cleaning easier and keeps lenses clean for longer.

Changing single-vision lenses starts from €30. The final price depends on the prescription, the lens index, the type of frame and the treatments chosen.

If your frame is in good condition, changing only the lenses is usually cheaper than buying a complete new pair of glasses, especially if your frame is a designer one or very comfortable.

In most cases yes, but it depends on the condition, shape and mounting system. Full-rim frames are the simplest; rimless, sports or highly curved ones require a more careful assessment.

Yes. Plastic or acetate glasses are usually very well suited to changing prescription lenses.

Yes, we also fit single-vision lenses into metal glasses, as long as the frame is in good condition.

Yes, although this type of mounting is more technical and may carry a surcharge, as it requires drilling or special adjustment.

We need to receive your frame to fit the new lenses. If you are worried about being without your glasses, ask us before ordering so we can reduce the time without them as much as possible.

Yes. If the frame is suitable, we fit single-vision prescription sun lenses with UV protection, tint or polarisation depending on availability.

When they are scratched, you see blurry, you feel eye strain, the coating has deteriorated or your prescription has changed.

For daily use, at least anti-reflective and hardened. If you work many hours with screens, the blue-light filter is a good option. To use the same glasses indoors and outdoors, photochromic lenses.

Yes. It improves visual comfort, reduces reflections and makes the lens more transparent. Very useful for driving at night and in artificial light.

Lenses with a treatment designed to improve visual comfort when facing digital screens such as a computer, phone or tablet.

Lenses that darken in sunlight and lighten indoors. Useful for using a single pair of glasses in different lighting conditions.

For low prescriptions 1.5 is usually enough; for medium ones, 1.6; for high ones, 1.67 or 1.74.

You can enter it on the website, upload your prescription, send it by email or contact us so we can help you.

Send us a photo with your glasses on or ask us before ordering. We will tell you how to obtain that measurement correctly.

Yes, for single-vision glasses we can read the prescription from your current lenses. This option is not valid for progressive glasses.

Yes, they come with a 3-year warranty against manufacturing defects.
