Specialty Contact Lenses

Newcastle Vision Clinic offers a wide selection of contact lenses including disposable soft contact, bifocal/multifocal, toric, colored lenses, and gas permeable (GP). Whether you wear daily, weekly or monthly disposables, check out our selection of lenses that fit your needs.

In addition to fitting standard contact lenses our doctors are trained in fitting specialty contact lenses including scleral lenses and GPs to fit irregular corneas (from keratoconus, pellucid marginal degeneration corneal graft) and treat dry eyes.


Keratoconus is a relatively uncommon eye condition where the cornea (the clear front window of the eye) becomes thinner and bulges forward. As the condition progresses, the shape of the cornea is altered, which distorts vision. Usually, keratoconus affects both eyes, although symptoms and progression in each eye may differ.

Gas permeable or scleral contact lenses are the treatment option of choice for mild and moderate keratoconus. They also can correct vision problems caused by keratoconus that cannot be corrected as well with eyeglasses or soft contacts.

Scleral Lenses

If you want to wear contact lenses but have had trouble wearing them in the past — or you’ve been told you are not a good candidate for contacts due to irregular corneas or keratoconus— scleral contact lenses may be the solution you are looking for.


These large-diameter gas permeable (GP) lenses offer the same advantages that conventional GP lenses have compared with soft contacts, including:

  • Sharper vision

  • Greater durability

  • Easier handling

  • Less risk of complications

They are called “scleral” lenses because, instead of covering only a portion of the cornea (like conventional GP lenses), these large GP lenses vault over the entire corneal surface and rest on the “white” of the eye (the sclera).

Because of their size, scleral lenses are more stable on the eye than conventional GP lenses — so they are less likely to accidentally dislodge from the eye. This stability also can make them more comfortable than conventional GP lenses; scleral lenses provide initial comfort similar to soft lenses, especially for sensitive eyes or irregularly shaped corneas.
