When selecting a new pair of glasses, we naturally focus on choosing frames that look great and feel comfortable. But how much time do we give to the lenses inside them? And how suitable they are to the activities we might be performing while wearing them? The right lenses can improve not only how clearly you see, but how comfortably you move throughout your day.

At John Fell Opticians, we believe that eyewear should support your lifestyle, not limit it. Whether you spend long hours on screens, enjoy outdoor activities, drive frequently, or need support for reading and close work, there is a lens designed to help you see at your very best.

With so many lens options now available – from single vision lenses to premium varifocals, light-reactive technology, and digital-use lenses – it’s completely normal to feel unsure about which is right for you. This guide will walk you through the different types of lenses we can use in glasses, explain their benefits, and help you understand how we tailor our recommendations to each individual patient.

And remember: if you ever feel uncertain, our experienced team is always here to help you make a confident, informed choice.

Why Lens Choice Matters

Your prescription tells us what correction your eyes need, but choosing the right lens determines how you experience that correction throughout your day.

The wrong lens can lead to:

• Eye strain
• Headaches
• Fatigue
• Poor visual transitions
• Reduced clarity in certain environments

The right lens, on the other hand, can transform your comfort and visual performance.

Modern lenses are far more advanced than many people realise. Today’s technology allows lenses to be customised not just to your prescription, but to your daily habits: from working at multiple screens to switching between near and distance vision.

As part of any first appointment or consultation with John Fell Opticians, we take time to understand how you use your eyes. Do you commute? Work on a computer or laptop? Play sports? Enjoy reading? Travel often? Your answers guide our recommendations.

It’s also worth noting that many people benefit from owning more than one pair of glasses. Just as you wouldn’t rely on one pair of shoes for every activity, different lenses can serve different purposes. For example:

• Everyday wear
• Computer work
• Driving
• Reading
• Sun protection

Our goal is simple: to help you see comfortably in every situation.

Single Vision vs. Varifocal

One of the first big decisions when choosing glasses lenses is whether you need single vision or varifocal lenses.

Single Vision Lenses

Single vision lenses correct one field of vision – typically distance or near.

They are ideal for:

• Younger glasses wearers
• Those with straightforward prescriptions
• Reading glasses
• Dedicated computer glasses
• Driving glasses

They provide a wide, uninterrupted viewing area and are often the easiest type of lens to adapt to.

However, as our eyes naturally change with age (usually from our early-to-mid 40s), many people develop presbyopia, a condition that makes focusing on close objects more difficult. This is where varifocals come in.

Varifocal Lenses

Varifocal lenses (sometimes called progressive lenses) allow you to see clearly at multiple distances within a single lens.

Instead of switching between separate pairs of glasses, varifocals provide:

• Distance vision at the top
• Intermediate vision in the middle
• Near vision at the bottom

All without visible lines on the lens.

They are particularly beneficial for people with busy, dynamic lifestyles who don’t want the inconvenience of constantly changing glasses.

While some wearers worry about adjusting to varifocals, modern designs have improved dramatically, offering smoother transitions and wider viewing zones than ever before. If you purchase varifocals as part of a consultation at a John Fell Opticians, we will carefully measure your lenses and frame fit to maximise comfort from the start.

Why We Choose Premium Brands Like Essilor

Not all varifocals are created equal. Premium lens manufacturers such as Essilor have developed highly advanced designs that use sophisticated calculations to enhance clarity and reduce visual distortion.

Premium varifocals offer:

• Wider fields of vision
• Faster adaptation
• Less “swim” effect when moving
• Sharper peripheral vision
• More natural visual transitions

While they may be slightly more expensive, Essilor lenses are truly worth every penny. They are particularly valuable for first-time varifocal wearers or those who rely heavily on crisp vision throughout the day. Some are even designed to support today’s visually demanding lifestyles, accounting for frequent head movement, screen use, and the need to refocus quickly between distances.

If you’ve struggled with varifocals in the past, it may simply be that you were not using the right design. Our team are very experienced in matching patients with lenses that genuinely suit their needs.

Blue-Light and Digital-Use Lenses

Our eyes were never designed to spend hours focusing on digital screens, yet for many of us, this is now unavoidable.

Extended screen time can contribute to:

• Eye fatigue
• Dry eyes
• Blurred vision
• Headaches
• Difficulty focusing

Digital-use lenses are designed to reduce visual strain by supporting your eyes during prolonged near and intermediate tasks.

Some lenses include blue-light filtering technology, which may help improve visual comfort in artificial lighting environments. While blue light itself is still being widely researched, many patients report feeling less fatigued when using these lenses.

They are particularly suited to:

• Office workers
• Students
• Gamers
• Hybrid workers
• Anyone regularly using tablets or smartphones

Even if you already wear varifocals, you might benefit from a dedicated pair of computer glasses – something our optometrists can advise on.

Photochromic (Light-Reactive) Lenses

If you frequently move between indoor and outdoor environments, photochromic lenses can be a gamechanger.

These clever lenses automatically darken in sunlight and return to clear when in lower natural light levels indoors, offering continuous comfort without the need to switch to sunglasses.

Benefits include:

• Built-in UV protection
• Reduced glare
• Improved comfort in bright conditions
• Convenience: you need just one pair instead of two

They are ideal for:

• People who are often on the go
• Drivers
• Walkers
• Gardeners
• Holidaymakers
• Anyone sensitive to light

Many patients still prefer prescription sunglasses for driving or prolonged outdoor use, as some windscreens filter the UV light needed to activate photochromic lenses, but it’s always best to be aware of all the options.

Thinner and Lighter Lens Options

If you have a stronger prescription, lens thickness can often be a concern — both visually and in terms of comfort. However, lens technology has greatly advanced in recent years to allow us to reduce this thickness through high-index lenses.

High-index lenses are specially designed to be:

• Thinner
• Lighter
• More cosmetically appealing
• Comfortable for all-day wear

They also tend to sit better within the frame, improving both appearance and balance. 

Even with a higher strength prescription, you now no longer have to worry about your favourite frames not fitting to your required lenses. You can enjoy a sleek and stylish look, without compromising on visual performance.

Lens Coatings and Their Benefits

Outside of the composition of the lenses themselves, we can also add lens coatings to enhance or enable different properties. Lens coatings are often overlooked, but they can dramatically enhance both durability and visual clarity for day-to-day and specialist activities.

1. Anti-Reflective Coating
   Reduces glare from headlights, screens, and overhead lighting – particularly useful for driving at night.
2. Scratch-Resistant Coating
   Adds resilience against everyday wear and tear.
3. Smudge-Resistant Treatments
   Help repel fingerprints, dust, and water, making lenses easier to clean.
4. UV Protection
   Safeguards your eyes from harmful ultraviolet rays.
5. Anti-Fog Options
   Ideal for mask wearers, sports enthusiasts, or anyone moving between temperature changes.

Think of coatings as an investment in the longevity and performance of your lenses.

Recommendations Based on Lifestyle

Wearing glasses should never stop you living the life you want or enjoying the things you want to. When recommending lenses, we look beyond prescriptions to understand how you truly use your eyes. 

Here are some examples of just some of the types of patients we have and what we have recommended for them:

The Office Professional:
Varifocals or digital lenses with anti-reflective coatings for long screen hours.

The Active Lifestyle:
Lightweight lenses with impact resistance and prescription sunglasses.

The Avid Reader:
Dedicated reading glasses or enhanced near-vision lenses.

The Frequent Driver:
Anti-glare coatings and possibly prescription sunglasses.

The Multitasker:
Premium varifocals that adapt to changing visual demands.

While we will try to find the perfect pair of glasses with lenses that suit all daily activities, many patients ultimately discover that having multiple pairs offers the best visual experience. Whether this is as simple as clear lenses vs. sunglasses or more complex with bifocal or varifocal options, our optometrists can work with you to ensure your eye care suits your lifestyle.
