HEINE A.R. Lenses

Aspheric ophthalmic lenses for indirect ophthalmoscopy

The HEINE A.R. Lenses are high-quality aspheric diagnostic lenses designed for indirect ophthalmoscopy and detailed examination of the fundus and retina. They complement HEINE indirect ophthalmoscopes such as the OMEGA 600, OMEGA 500, SIGMA 250 and MONOCULAR and allow the examination setup to be adapted to different diagnostic requirements.

Different lens powers provide different combinations of magnification, field of view and working distance. The choice of lens is therefore an important part of professional indirect fundus examination.

Aspheric optics for professional fundus examination

A.R. – Anti-Reflection

HEINE A.R. lenses feature an anti-reflective coating designed to minimise disturbing reflections and optimise light transmission during examination.

Combined with their aspheric optical design, this supports a clear and detailed view of the fundus.

The lenses are designed for professional use in:

• ophthalmology practices;
• eye clinics;
• hospitals;
• outpatient ophthalmology;
• retinal examinations;
• mobile ophthalmic diagnostics.

Why are lenses required for indirect ophthalmoscopy?

In indirect ophthalmoscopy, a condensing lens is held between the patient’s eye and the ophthalmoscope.

The lens creates an aerial image of the fundus that can then be observed through the indirect ophthalmoscope.

The selected dioptric power influences several important examination characteristics:

• magnification;
• field of view;
• working distance;
• overview of the retina;
• visibility of peripheral retinal areas.

There is therefore no single lens that is optimal for every examination.

Different lens powers for different examinations

HEINE offers A.R. lenses with different dioptric powers. This allows ophthalmologists to select the lens according to the required relationship between magnification and field of view.

As a general principle:

lower dioptric power → higher magnification and narrower field of view

higher dioptric power → lower magnification and wider field of view

This makes the lens itself an important component of the diagnostic system.

HEINE A.R. 16 D Lens

Higher magnification for detailed examination

A 16 D lens provides comparatively high magnification and is therefore particularly interesting when detailed observation is more important than achieving the widest possible field of view.

Its characteristics make it suitable for targeted examination of retinal structures where additional magnification is desirable.

HEINE A.R. 20 D Lens

The versatile standard for indirect ophthalmoscopy

The 20 D lens is a classic all-round choice for binocular indirect ophthalmoscopy.

It provides a balanced relationship between:

• magnification;
• field of view;
• working distance;
• handling.

For many general fundus examinations, 20 D is therefore a particularly versatile lens power.

If a practice or clinic wants to start with one general-purpose lens, the 20 D version is often the logical choice.

HEINE A.R. 30 D Lens

Wider field of view for a better overview

With increasing dioptric power, the field of view becomes wider while magnification decreases.

A 30 D lens is therefore particularly useful when a broad overview of the retina is required.

It can also be advantageous when a shorter working distance is preferred.

Magnification or field of view?

Choosing the appropriate A.R. lens

The ideal lens depends on the diagnostic objective.

The principle can therefore be summarised simply:

More detail → lower dioptres

Balanced examination → approximately 20 D

Wider overview → higher dioptres

A.R. lenses with HEINE OMEGA 600

The HEINE OMEGA 600 is HEINE's high-end binocular indirect ophthalmoscope.

Combined with an appropriate A.R. lens, the system provides a professional solution for detailed examination of the fundus, retina and retinal periphery.

Different lens powers allow the ophthalmologist to adapt the examination according to whether magnification or a wider field of view is the priority.

A.R. lenses with HEINE OMEGA 500

The OMEGA 500 can also be combined with suitable ophthalmic lenses for professional binocular indirect ophthalmoscopy.

A 20 D lens provides a particularly versatile starting point for general fundus examination, while other dioptric powers allow the examination characteristics to be adapted to specific requirements.

A.R. lenses with HEINE SIGMA 250

The compact HEINE SIGMA 250 also requires a suitable condensing lens for indirect fundus examination.

Combining the lightweight SIGMA concept with an A.R. lens creates a particularly flexible system for mobile binocular indirect ophthalmoscopy.

A.R. lenses with HEINE MONOCULAR

The HEINE MONOCULAR can also be used with a suitable ophthalmic lens for indirect examination.

This combination is particularly interesting for hospital rounds and mobile fundus examinations, where the compact dimensions of the MONOCULAR are an important advantage.

High-quality lens for professional ophthalmology

A diagnostic lens is not merely an accessory. In indirect ophthalmoscopy, it is an essential optical component of the examination system.

Lens quality directly influences the examiner’s view of the fundus. Important factors include:

• optical quality;
• effective anti-reflective coating;
• image clarity;
• comfortable handling;
• suitable lens power for the examination.

HEINE A.R. lenses are designed to complement professional HEINE ophthalmic diagnostic instruments.

Which HEINE A.R. lens should I choose?

The choice depends primarily on the intended examination.

For a balanced general-purpose lens

The 20 D lens is the classic choice, providing a good balance between magnification and field of view.

For greater magnification

A lens with a lower dioptric power, such as 16 D, is more suitable when detailed observation is the priority.

For a wider field of view

A lens with a higher dioptric power, such as 30 D, provides a wider overview with correspondingly lower magnification.

For practices and clinics performing a wide range of retinal examinations, it can therefore be useful to have several lens powers available.

HEINE A.R. Lenses – overview

Who are HEINE A.R. Lenses designed for?

HEINE A.R. lenses are designed for:

• ophthalmologists;
• eye clinics;
• ophthalmology departments;
• retinal specialists;
• outpatient ophthalmology;
• mobile ophthalmic examinations;
• professional users of indirect ophthalmoscopes.

They are particularly relevant wherever the examination of the fundus needs to be adapted to different requirements for magnification and field of view.

Why choose HEINE A.R. Lenses?

The main advantages are the combination of:

aspheric optics + anti-reflective coating + different dioptric powers + professional indirect ophthalmoscopy + compatibility with the HEINE diagnostic concept

For users of HEINE indirect ophthalmoscopes, A.R. lenses are therefore a logical addition to a professional fundus examination system.

Frequently asked questions about HEINE A.R. Lenses

What are HEINE A.R. Lenses used for?

They are ophthalmic diagnostic lenses used in indirect ophthalmoscopy for examination of the fundus and retina.

What does A.R. mean?

A.R. refers to the anti-reflective coating of the lens, designed to reduce disturbing reflections during examination.

Which lens is suitable for general indirect ophthalmoscopy?

A 20 D lens is a classic and versatile choice because it offers a balanced relationship between magnification, field of view and working distance.

What happens when the dioptric power increases?

With a higher dioptric power, the field of view generally increases while magnification and working distance decrease.

Which lens provides greater magnification?

A lens with a lower dioptric power, such as 16 D, provides greater magnification than a higher-power lens.

Which lens provides a wider field of view?

Higher-power lenses, such as 30 D, provide a wider field of view and are useful when a broad retinal overview is required.

Are HEINE A.R. Lenses only accessories?

Technically they are accessories to the indirect ophthalmoscope, but diagnostically the lens is an essential part of the optical examination system. Indirect ophthalmoscopy cannot be performed in the intended way without an appropriate condensing lens.

Can different A.R. lenses be useful in the same practice?

Yes. Different lens powers allow the ophthalmologist to switch between greater magnification and a wider retinal overview, depending on the examination.
