Understanding Presbyopia Through Simulation

As we age, the natural lens of the eye gradually loses flexibility, making it harder to focus on objects at varying distances — a condition known as presbyopia. This simulator has been designed to help you experience how this common age-related vision change can affect your ability to focus on near, intermediate, and distant objects.

By toggling between vision zones, you’ll gain a clearer understanding of where your eyesight may be struggling and why treatments such as presbyopia-correcting lens implants or advanced laser eye surgery can restore balance across all distances.

If you find that one or more zones are consistently blurry, it may be time to book a consultation and explore your options with a specialist.

Near Vision
(Phone Use, Reading, Fine Detail Work)

Near vision allows us to clearly focus on objects within 30–40 cm — like reading a book, checking your phone, or threading a needle. As the eye ages, the crystalline lens stiffens, reducing its ability to accommodate for close-up tasks — a condition known as presbyopia.

Treatment Options

Presbyopia-correcting lens exchange (multifocal or trifocal IOLs) offers sharp vision at near, intermediate, and far distances, reducing or eliminating the need for reading glasses.

PRESBYOND® laser blended vision is another modern laser option that extends the eye’s depth of focus, blending near and distance vision in a customised way for each eye.

Intermediate Vision
(Laptops, Dashboards, Kitchen Counters)

Intermediate vision covers the range between 50 cm and 1.5 metres — where we interact with screens, dashboards, and household items. Presbyopia can blur this middle distance, making daily tasks increasingly frustrating, especially in low light.

Treatment Options

  • Trifocal lens implants correct intermediate as well as near and distance vision, providing smooth transitions between focal points.

  • Laser blended vision also enhances intermediate focus by creating a continuous range of vision across zones using wavefront-optimised laser profiles.

Distance Vision
(Driving, Watching TV, Outdoor Landscapes)

Distance vision (typically beyond 2 metres) allows us to see objects clearly across a room or far away — vital for driving, recognising faces, or enjoying scenic views. Refractive errors like hyperopia, and astigmatism can blur distance vision, while ageing lenses add another layer of complexity.

Treatment Options

  • Laser eye surgery (SMILE®, LASIK, or PRK) corrects the shape of the cornea to restore distance clarity with precision.

  • Implantable Collamer Lenses (ICL) are ideal for patients with high prescriptions or thin corneas, offering HD-quality vision without reshaping the cornea.

  • Refractive lens exchange (RLE) also restores distance vision while correcting presbyopia in a single procedure for patients over 45.

How Blended Vision Expands Depth of Field

New surgical techniques such as laser blended vision or trifocal lens implants work by creating or restoring a blend zone — a seamless transition area that bridges near, intermediate, and distance vision. This blend zone isn’t a fixed point but a carefully calculated range where the eye maintains clarity across focal distances, much like widening the aperture in a camera for a greater field of focus.

With a broader depth of field, the eye can naturally adjust to multiple distances without the abrupt focus drop-offs that come with standard monovision or bifocal solutions.

What This Means For You

If you’re experiencing blurry vision when switching between your phone, your laptop, and the world around you, you may be entering the early stages of presbyopia. But thanks to advanced treatments like PRESBYOND® blended vision, trifocal lens exchange, and ICLs, there’s no need to settle for reading glasses or limited vision zones.

LASER EYE SURGERY

Laser vision correction provides a precise, minimally invasive solution for refractive errors such as nearsightedness, farsightedness, and astigmatism. Using advanced techniques like SMILE Pro, Femto-LASIK, and Presbyond, these treatments reshape the cornea to restore sharp, natural vision.

LENS CORRECTION

Lens-based treatments offer cutting-edge solutions for vision correction, including implantable contact lenses (ICL), refractive cataract surgery, and multifocal or trifocal lenses. These advanced options are ideal for patients with severe refractive errors, presbyopia, or cataracts, providing sharp vision at all distances.

CONDITIONS

We offer specialised treatments for a range of vision conditions, including astigmatism, cataracts, myopia, hyperopia, presbyopia, and keratoconus. By taking a personalised approach, we address the root causes of vision problems, ensuring precise and long-lasting results with state-of-the-art technology.
