Contact Lens Fittings (including multifocals, torics, rigid gas permeable and lenses for keratoconus) 

Contact lenses are used to correct some of the same conditions found in the measurement of your vision (the refraction).

Dr. Johnson performs a detailed exam of your cornea, including making measurements of the corneal shape to fit the contact lens that is best for your prescription and lifestyle.

Types of Contact Lenses

Developments in materials and designs of contact lenses are constantly changing as newer technology improves on previous contact lenses. Recent developments include toric (astigmatism-correcting) lenses which are replaced on a daily basis and the development of lenses which allow enough oxygen to pass through the lens that they can be worn on an overnight basis

Disposable Contact Lenses

Disposable contact lenses are lenses which are designed to be replaced on a regular basis, usually either daily, two-weekly or monthly. The more often a lens is replaced, the less the lens will become deposited with proteins and oils. Many of the problems that contact lens wearers experienced when contact lenses were replaced on an annual basis are seldom seen nowadays. Disposable contact lenses are therefore a healthier alternative. Daily disposable contact lenses are a great option for people who only want to wear their contact lenses a few times per week, for example, for sports. They also remove the need for cleaning, since they are inserted in the morning (or before you play sports) and then thrown away afterward, offering exceptional convenience and good value for the money. Lenses which are replaced bi-weekly or monthly are a good value if you want to wear lenses every day.

Gas Permeable Contact Lenses

Gas permeable contact lenses are typically used for the correction of moderate levels of astigmatism. They provide excellent clarity of vision, especially in cases where the astigmatism is irregular (such as with keratoconus). Gas permeables do require a longer period of adaptation than soft lenses, but they offer excellent long-term corneal health since they allow almost as much oxygen to pass through to the cornea as without a lens on the eye. Many of the problems associated with the reduced oxygen flow through the old-style "hard lenses" are seldom seen nowadays due to the developments in these modern gas permeable materials.
