Two prescriptions in one lens
Distance and Reading Vision in One Pair
Bifocal lenses combine two prescriptions in one lens. The main lens is normally used for distance vision, while a clearly defined lower segment provides reading vision.
Unlike varifocals, there is no gradual progression between distances. You move directly from the main viewing area into the visible reading segment.
Clear vision for the tasks that matter
Distance and reading — or an occupational combination
Bifocals can be configured for everyday distance and near vision or, where suitable, for specific working distances.
Computer & close work
In some occupational designs, the upper area can support intermediate vision with a closer reading segment below.
Familiar, defined zones
A visible segment gives an immediate change between the two prescriptions without a gradual corridor.

Bifocal or varifocal?
Prefer Clearly Defined Viewing Areas?
Bifocals can be a good option if you are already comfortable with a visible reading segment or prefer an immediate change between distance and near vision.
Two defined viewing areas
Distance vision in the main lens with a visible reading segment below. There is an immediate change between the two powers.
- Visible reading segment
- Direct distance-to-near change
- Familiar for existing bifocal wearers
Gradual vision across distances
Distance, intermediate and near vision are blended through the lens without a visible dividing line.
- No visible segment
- Includes intermediate vision
- Progressive transition between distances
D28 and C28 segments
D28 or C28 — We Can Help You Keep What Feels Familiar
D28 is the most commonly selected bifocal segment, with a flat-topped reading area measuring approximately 28mm across.
C28 lenses are also available at exactly the same price. If you already wear bifocals, please keep your current prescription lenses fitted when sending the glasses. We use them alongside your prescription details to replicate the important measurements and segment position for your new lenses.

Keep Your Current Prescription Lenses Fitted
If you already wear bifocals, please send the glasses with the current prescription lenses still fitted. They help us assess important fitting information such as the segment position.
New, empty or dummy-lens frame?
Please also send an existing pair of prescription glasses that we can use for measurement.

Frequently asked questions
Questions before you order
What are bifocal lenses?
Bifocal lenses contain two prescriptions in one lens, usually distance vision through the main lens and reading vision through a visible lower segment.
What is the difference between bifocals and varifocals?
Bifocals provide two clearly defined prescriptions with a visible segment. Varifocals change gradually between distance, intermediate and reading vision without a visible line.
What is a D28 bifocal lens?
D28 is a common flat-top bifocal design with a reading segment measuring approximately 28mm across.
Can I choose C28 lenses instead?
Yes. C28 lenses are available at the same price as D28 lenses.
Can bifocals be made for computer and reading use?
In some cases, bifocals can be configured as an occupational design with intermediate vision in the main lens and a closer reading prescription in the lower segment. Suitability depends on your prescription and intended use.
How much do bifocal replacement lenses cost?
Standard 1.5 index D28 or C28 bifocal lenses start from £31.50 uncoated, £40.50 with Ultra Tough and £49.50 with Ultra Enhanced. Thinner 1.6 and 1.67 options are also available.
Can I add anti-reflection coating?
Yes. Ultra Enhanced lenses include scratch resistance and anti-reflection coating.
Can I add tinted, polarised or Transitions® lenses?
Yes. Tint and UV is available for an additional £12. Polarised and Transitions® upgrades are available for an additional £50.
Do you check my order before making the lenses?
Yes. An experienced member of our optical team reviews the supplied prescription, lens choices and frame information. We will contact you if anything needs clarification.
Can you reglaze my existing bifocal glasses?
Yes, provided the frame is in suitable condition and has enough lens depth for the required bifocal segment. Every frame is inspected before work begins.
How do I send you my glasses?
After ordering, we send you a protective pack with instructions and a prepaid UK postage label so you can return your glasses securely.
How long does bifocal reglazing take?
Completion time depends on the selected lens and any specialist options. You will be kept informed if an order requires additional manufacturing time.
