Hard Contact Lenses Melbourne | RGP Lenses

Why Rigid Still Beats Soft For Some Eyes

Soft lenses flex to the shape of the eye, which is exactly what makes them so comfortable straight away, but it also means they drape over corneal irregularities rather than correcting them. A rigid gas-permeable (RGP) lens holds its own precise shape instead, so light entering the eye passes through a genuinely smooth, consistent optical surface no matter how irregular the cornea underneath is.

That precision is why RGP lenses often outperform soft lenses for higher astigmatism, keratoconus, and other irregular corneal shapes, and why many wearers find they're actually less prone to dryness, since a hard lens doesn't rely on drawing moisture from the tear film the way a soft lens does.

FIG. 01 — RGP LENS DESIGN

Lens Types

Designed Around Your Prescription And Corneal Shape

Spherical RGP

A standard rigid design for regular corneas needing sharp, stable correction beyond what soft lenses provide.

Toric RGP

Rigid correction for higher or irregular astigmatism that soft toric lenses don't quite stabilise.

Keratoconus RGP

Custom-designed using corneal topography to correct the irregular corneal shape keratoconus causes.

Bifocal & Multifocal RGP

Rigid multifocal designs for presbyopia, for wearers who want the optical sharpness of a hard lens at every distance.

Common Questions

Hard Lens Questions We're Asked Often

Are hard contact lenses uncomfortable compared to soft lenses?

There's usually an adaptation period of one to two weeks as your eyes get used to the sensation, since a rigid lens does feel different at first. Most wearers adjust well within that window, and many find the sharper vision and lower dryness through the day makes it genuinely worthwhile.

Why would I choose a hard lens over a soft one?

Optical quality is the main reason: a rigid lens holds its shape precisely, giving sharper, more consistent vision, particularly for higher astigmatism or irregular corneas that soft lenses correct less accurately. Hard lenses also don't rely on the tear film the way soft lenses do, which often means less dryness.

Can children wear hard contact lenses?

Yes. Because rigid lenses are smaller than soft lenses and don't flip or fold, many children actually find them easier to handle, including for orthokeratology fitted specifically for myopia control.

How long do hard contact lenses last?

With proper care, RGP lenses typically last 12 to 18 months, which often makes them more economical over time than a comparable soft lens replacement schedule.

How much do hard contact lenses cost?

Hard, or rigid gas permeable (RGP), lenses generally involve a higher upfront cost than soft lenses because each pair is custom manufactured to your exact corneal measurements, but their longer lifespan of 12 to 18 months often narrows the gap in cost per year. We give you an exact, itemised quote once we've completed your fitting.

Why would an optometrist recommend hard lenses over soft lenses for keratoconus?

A rigid lens holds its shape over an irregular cornea and creates a smooth, uniform optical surface, effectively masking corneal irregularity in a way a flexible soft lens simply can't. For keratoconus and other irregular corneas, this often means significantly clearer vision than glasses or soft lenses can achieve. See our keratoconus and scleral lens pages for more detail.

Is it hard to adapt to wearing rigid contact lenses?

There's typically a short adaptation period, often one to two weeks, during which lens awareness settles as your eyes and eyelids adjust. Most patients find that persisting through this initial adjustment is worthwhile given the sharper vision rigid lenses provide, and we support you through that period with follow-up visits.

Can hard contact lenses be used for orthokeratology as well as daytime wear?

Yes, orthokeratology (OrthoK) uses a specially designed rigid lens worn overnight to reshape the cornea, giving clear vision during the day without any lens in the eye at all, which is different from daytime RGP wear. See our OrthoK and myopia management pages for how overnight rigid lens wear compares with daytime rigid lens correction.

What happens if I stop wearing hard contact lenses after years of use?

Your vision generally returns towards its underlying prescription over some weeks, though patients with irregular corneas who've relied on rigid lenses to mask that irregularity will usually see a more noticeable drop in unaided clarity. We can talk through what to expect for your specific case before you make any change to your lens wear.

Where can I get fitted for hard contact lenses in Melbourne?

We fit rigid, hybrid and scleral lenses at our Kew East practice, including complex cases involving keratoconus and irregular corneas that other practices have found difficult to fit. We see patients from across Melbourne's inner east and further afield specifically for rigid lens fittings.
