Specialty Contacts in Calgary

While standard gas permeable contact lenses only cover the surface of the cornea, scleral lenses also cover a portion of the sclera (the white part of the eyes).

A scleral lens vaults over the cornea, resting on the edges of the sclera, rather than laying directly against the cornea. Since the lens never comes into contact with the cornea, this lens is beneficial for many corneal conditions.

Many patients find scleral lenses to be more comfortable and stable, particularly patients with “hard to fit” eyes, such as with keratoconus or pellucid marginal degeneration.

Scleral contacts are also effective for extreme cases of dry eye. The unique shape acts as a reservoir, holding tears to hydrate the eye.

Contacts wearers typically love the clarity of hard lenses but prefer the comfort of soft lenses. Hybrid contact lenses combine the best of both a rigid gas permeable lens and a soft lens. The rigid centre region offers superior vision, particularly in the case of irregular corneas. The soft outer section (or skirt) provides better comfort and fitting characteristics.

Although soft lenses are best known for their comfort, soft lenses are also great for more complicated vision correction. For some patients, options like the NovaKone lenses provide significantly better vision than glasses or regular contacts. There are even soft lenses for those with higher prescriptions (Spherical from +30.00 to -30.00 and astigmatism up to -10.00).

As our eyes age, we experience changes to our visual abilities. Significant changes to our vision tend to occur by our late 40s. One universal eye issue related to aging is difficulty focusing, usually caused by presbyopia. It’s the age when everyone needs reading glasses, even if you’ve had perfect vision all your life.

Age-related changes can complicate things, more so if you already need glasses to correct your distance vision. Multifocal contacts offer multiple corrective powers or prescriptions within different margins of a single lens. With multifocal lenses, you can see clearly at all distances without changing your eyewear.
