With the acquisition of a very manual process - every employee on the production line, whether they were lathing, polishing or inspecting, handled the lenses - scaling up the business was very limited, so Vistakon decided to invest into a new production process.

Examples of retailers that currently offer this technology are Freshlook Color Studios and Colorful Eyes. Multifocal contact lenses are typically designed for constant viewing through the center of the lens, but some designs do incorporate a shift in lens position to view through the reading power similar to bifocal glasses.

Lenses replaced frequently gather fewer deposits of allergens and germsmaking these lenses preferable for patients with ocular allergies or for those who are prone to infection.

Curving of the lines of printed dots suggests these lenses were manufactured by printing onto a flat sheet then shaping it. Rotating molds are used and the molten material is added and shaped by centripetal forces. Injection molding and computer control are also used to create nearly perfect lenses.

Although the Vistakon name is still used in the United States, it was changed to Johnson and Johnson Vision Care in due to global expansion. Contact lenses made from these materials are called rigid gas permeable lenses or 'RGPs'.

Wearing lenses designed for daily wear overnight has an increased risk for corneal infections, corneal ulcers and corneal neovascularization —this latter condition, once it sets in, cannot be reversed and will eventually spoil vision acuity through diminishing corneal transparency.

As a result Acuvue was introduced to the market in InAdolf Gaston Eugen Fick was the first to successfully fit contact lenses, which were made from blown glass InGerman ophthalmologist Adolf Gaston Eugen Fick constructed and fitted the first successful contact lens.

These lenses may also correct refractive error. With the acquisition of a very manual process - every employee on the production line, whether they were lathing, polishing or inspecting, handled the lenses - scaling up the business was very limited, so Vistakon decided to invest into a new production process.

The lens was originally indicated for seven-day extended wear and later became a daily wear lens. This is for safety reasons so the lenses will fit the eye without causing irritation or redness.

Chemist Norman Gaylord played a prominent role in the development of these new oxygen-permeable contact lenses. A lens hindering passage of oxygen to the cornea causes corneal hypoxia which can result in serious complications, such as corneal ulcer that, if left untreated, can permanently decrease vision.
