Introduction: Past two decades have seen a steep rise in the usage of contact lenses and that brought a major revolution in the materials research, design and manufacturing technologies. This also impacted the optometrists thus influencing the patient usage, modalities and duration. The current article briefs the changes in the field of contact lenses and the changing trends.

Methods: Contact lens materials and its manufacturing, wearing modalities and changing trends in prescribing them were identified, reviewed and summarized as per the topic requirements from scientific papers, authentic articles, books and websites to cover the challenges our ancestors have faced and the solutions that were provided in the past were summarized for the reader in an easy accessible way.

Conclusion: Newer generation of contact lens materials made an average contact lens wearer comfortable by wearing lenses for longer hours without discomfort and with minimal complications. Due to the advent of newer lens materials, practitioners have been given more options for choosing a best suited lens based on specific wearer requirements and needs. In this way, newly available materials and designs make the lens wear safer and less prone to complications by shifting the patient from conventional to planned replacement lenses (PRL) and from PRL to daily disposables to ensure a healthy and safer vision.
