If you need help seeing both distance and near, you have probably come across two main options: bifocal lenses and varifocal lenses.

Both are designed to help with multiple viewing distances, but they work in very different ways. Choosing the right option depends on how you use your glasses, how comfortable you want the transition between distances to feel and what suits your lifestyle best.

At Burghley & Co, we help customers navigate these choices every day. As a UK Registered Dispensing Optician-led business, our focus is not simply on selling lenses — it is on helping customers choose eyewear that genuinely works for how they live and use their vision.

What are bifocal lenses?

Bifocal lenses contain two separate prescription zones within one lens.

Typically:

• The top section is used for distance vision.
• The lower segment is used for reading.

There is a visible line separating the two areas.

Bifocals have been used successfully for many years and can still work very well for certain wearers, particularly those who want clear separation between distance and reading tasks.

What are varifocal lenses?

Varifocal lenses work differently. Instead of having two separate zones with a visible line, varifocals gradually blend multiple viewing distances together in one lens.

This allows the wearer to move more naturally between:

• Distance vision
• Intermediate vision
• Reading vision

Varifocals are often considered a more modern and cosmetically cleaner solution because there is no visible reading segment.

The biggest visual difference

The easiest way to explain the difference is this:

• Bifocals give you two distinct viewing areas.
• Varifocals give you a gradual progression between distances.

With bifocals, there is usually a noticeable “jump” between the two prescription zones.

With varifocals, the transition feels smoother once adapted to properly.

Why many people now prefer varifocals

Varifocals have become increasingly popular because modern lifestyles involve much more intermediate vision than in the past.

Today we constantly move between:

• Phones
• Laptops
• Driving
• Reading
• Face-to-face conversation
• Cooking
• Screen work

Varifocals allow smoother movement between those distances without needing multiple pairs of glasses.

Why some people still choose bifocals

Bifocals still suit certain people very well.

Some wearers prefer:

• The wider reading area
• The simplicity of separate viewing zones
• Less peripheral distortion
• Minimal adaptation time

For customers who mainly switch between distance and reading without needing much intermediate vision, bifocals can remain an excellent option.

Do varifocals take time to adapt to?

Sometimes, yes.

Because varifocals blend multiple prescriptions into one lens, there is usually an adaptation period while your eyes and brain adjust to the lens design.

Most people adapt successfully within days or weeks, but poor fitting, unsuitable frames or basic lens designs can make adaptation harder.

This is one reason why some cheaper varifocals fail to deliver a comfortable experience.

Read our guide on why cheap varifocals often fail.

Frame choice matters with varifocals

Varifocal lenses generally need enough vertical depth within the frame to allow the distance, intermediate and reading zones to work properly.

Very shallow frames can sometimes limit the usable visual areas and reduce comfort.

That is why frame choice is just as important as lens choice.

What about lens thickness?

If you have a stronger prescription, lens thickness can become more noticeable in both bifocal and varifocal lenses.

Depending on the prescription and frame style, thinner lens materials may improve both comfort and appearance.

Which lenses are better for screens and office work?

This depends on how you use your glasses.

Varifocals generally provide more flexibility across different distances, especially for people regularly moving between screens, distance viewing and reading.

However, some customers who spend most of the day at a desk may benefit more from occupational lenses designed specifically for intermediate and near vision.

How Burghley & Co approaches multifocal lenses

At Burghley & Co, we believe choosing multifocal lenses should feel guided rather than overwhelming.

We focus on helping customers choose the right solution for:

• Their lifestyle
• Their working environment
• Their prescription
• Their frame choice
• Their comfort preferences

Our Confidence Policy and frame-first varifocal process are designed to give customers more reassurance when ordering prescription eyewear online.

Which option looks better cosmetically?

Most people prefer the appearance of varifocals because there is no visible reading segment.

Bifocals have a visible line separating the reading area, which some customers dislike aesthetically.

However, some wearers still appreciate the simplicity and practicality of bifocals despite the visible segment.

Are premium varifocals worth it?

For many people, yes.

Higher-quality varifocal lens designs often provide:

• Wider visual zones
• Smoother transitions
• Better intermediate comfort
• Reduced distortion
• Easier adaptation

This can make a significant difference for customers who wear their glasses throughout the entire day.

Final thought

There is no universal “best” choice between bifocal and varifocal lenses. The right option depends on how you use your vision day to day.

Bifocals can still work brilliantly for some wearers, while varifocals often provide a more seamless and modern visual experience for customers regularly moving between multiple distances.

At Burghley & Co, our goal is to make choosing prescription eyewear feel more personal, more transparent and more expertly guided — combining premium eyewear with real optical support online.

FAQs

Are varifocals better than bifocals?

Not necessarily. Varifocals provide smoother transitions between distances, while bifocals offer separate distance and reading zones. The best option depends on your lifestyle and comfort preferences.

Do bifocals have a visible line?

Yes. Traditional bifocals contain a visible reading segment within the lens.

Do varifocals take time to adapt to?

Most people need a short adaptation period when first wearing varifocals. Proper fitting and lens quality make a significant difference.

Which lenses are better for computer use?

Varifocals usually provide better intermediate vision than bifocals, making them more flexible for modern screen use. However, occupational lenses may sometimes be better for dedicated desk work.

Can bifocal and varifocal lenses both be made thinner?

Yes. Thinner lens materials are available for both bifocal and varifocal prescriptions depending on the prescription strength and frame choice.
