Contact Lens Modalities

Daily Disposable
From surfing and kayaking in the sea, to hiking and snowboarding in the mountains, Daily Disposable Contacts on Vancouver Island are the most convenient, hassle-free, healthy modality. Simply insert them in your eyes before your activity and remove them when you are done. Study after study has shown compliance is poor with lenses you have to clean with solutions, so the best solution is no solution at all.

In addition, several studies have shown replacement compliance is poor with monthly contact lenses and even poorer with bi-weekly contact lenses, so again daily becomes the winner for simplicity. Have Astigmatism? Not a problem – the Acuvue 1-Day Moist lenses for Astigmatism have proven to provide stable vision and excellent comfort – Valley Vision Optometry was one of the first offices to use these Contact Lenses on Vancouver Island.

Lastly, daily disposables are the lenses with the least propensity to cause eye health problems. For these reasons, our first choice, especially among tweens and teens on Vancouver Island are Daily Disposable Contact Lenses.

Two-week replacement Contact Lenses
These lenses pre-date daily disposables and require nightly cleaning and bi-weekly replacement. They apply for patients with a prescription range that falls outside of the parameters available in the daily disposable modality.

Compliant patients report better comfort than wearers of monthly disposable Contact Lenses simply because they are only wearing the lens for half the amount of days, however, compliance with replacement has been reported to be less than that of monthly disposables which then leads to a decrease in comfort and increase in complications.

Monthly replacement Contact Lenses
These lenses pre-date daily disposables and require nightly cleaning and monthly replacement. They apply for patients with a prescription range that falls outside of the parameters available in the daily disposable modality.

It has been reported that patients find it easier to comply with monthly replacement over two-week replacement Contact Lenses. What we recommend is our patients time their replacement with the changing of their calendar.

Quarterly replacement Contact Lenses
These lenses pre-date daily disposables and require nightly cleaning and replacement every three months. They apply for patients with a prescription range that falls outside of the parameters available in the daily, two-week, and monthly disposable modalities.

Yearly replacement Contact Lenses
These lenses are the original soft lens modality released in the 1970’s and pre-date all other soft modalities. They require nightly cleaning and replacement every year.

The use of these lenses is quite rare now and only apply for patients with a prescription range that falls outside of the parameters of all other modalities.
