Environmental impact of three replacement modalities of soft contact lens wear
Description
Purpose: To illustrate the environmental impact of three contact lens replacement modalities, and to place this into a broader environmental context. Methods: Environmental impact was calculated by sorting the packaging used in the supply of three representative contact lens systems into their constituent materials (liquid, plastic, paper, metal and glass), determining their mass, calculating the annualised consumption by a typical contact lens wearer, and factoring the data against published indices of the environmental impact of the constituent materials. Results: Conventional lens wear had the highest impact and planned replacement lens wear (monthly disposable) had the lowest impact. Conclusions: The overall environmental impact of waste generated thorough the use of contact lens products by the end consumer is insignificant (0.5%) compared with the amount of waste generated in our everyday life.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
