Disposable contact lenses are single-use lenses that are removed and discarded after use. These lenses are more convenient compared with reusable contact lenses. Increasing adoption of disposable contact lenses and popularity among practitioners are some of the major factors driving the market. As of 2021, at least 2.2 billion people across the globe have near or distant vision impairment. The most common reasons for vision impairment and blindness are uncorrected refractive errors and cataracts.

Establishments described in this report are primarily participating in the ultrafiltration market. Ultrafiltration is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate.
