If you're thinking about switching up your eye care routine or are new to contact lens wear, one of the first questions you'll come across is: hard contact lenses or soft contact lenses? Both types of contact lenses have their perks (and quirks), but the best option depends on your lifestyle, prescription, and how your eyes behave on a typical Tuesday. Before you jump into ordering contact lenses online, let’s break it down.

What are hard contact lenses?

Hard contact lenses, officially called rigid gas permeable (RGP) lenses, are made from durable materials that allow oxygen to pass through to the cornea. They’re smaller than soft lenses and rest directly on the surface of the eye.

You might also hear about:

  • PMMA lenses (polymethyl methacrylate): an older version with low oxygen permeability. Not used as much these days.
  • RGP lenses: today’s go-to for sharper vision and better eye health.


They do take some getting used to. Expect an adaptation period, but once your eyes adjust, the vision correction is top notch.

What are soft contact lenses?

Soft contact lenses are the crowd favourite, and for good reason. They’re made from flexible plastic materials like hydrogel and silicone hydrogel, which mould to your eyes and offer instant comfort.

There are a few popular types of soft lenses:


They’re breathable, comfortable and a solid pick if you’ve got dry eyes, mild myopia or refractive errors.

Which contact lens is best for your vision needs?

It really comes down to how and when you wear contact lenses, plus what’s going on with your cornea, retina or tear ducts.

Choose hard contact lenses if:

  • You need sharper vision due to keratoconus or high astigmatism
  • You've had corneal surgery or need precision for certain vision problems
  • You want something long-lasting and don’t mind a little patience


Choose soft lenses if:

  • You’ve got sensitive eyes or dry eyes
  • You’re after all-day comfort with minimal fuss

  • You need multifocal or toric options for presbyopia or mild astigmatism
  • You prefer disposable contact lenses or extended wear choices


Top tip: Your optometrist or eye doctor can help you decide the best route after an eye exam, especially if you're trying a new type of lens.

Comfort or clarity?

When it comes to the different types of contact lenses, there’s no one-size-fits-all. Hard lenses can offer brilliant clarity for complex prescriptions, while soft contact lenses deliver all-day comfort and flexibility for everyday life.
