# On-the-Fly Lens Adjustments Trufocal Glasses' Nosepiece Slider Adjusts Focus By Katie Cordrey | Published 2010-08-22 | Life-Stages Source: Trend Hunter, https://www.trendhunter.com/trends/trufocal-glasses References: [nytimes](http://www.nytimes.com/2009/08/04/science/04prof.html) & [trufocals](http://trufocals.com/) TruFocal glasses with a nosepiece slider can help people who just can't adjust to wearing regular bifocals or [progressive lenses](https://www.trendhunter.com/trends/highend-progressive-lens). The slider allows the wearer to adjust the glasses' focus so there is no need for muli-focal lenses that create lines or disorienting visual transitions. Trend Hunter previously reported on Josh Silver’s [Adaptive Eyewear](https://www.trendhunter.com/trends/prescription-on-demand) that uses water to regulate focus in third world countries, but Stephen Kurtin's TrueFocal glasses use a combination fixed prescription lens and a [liquid-filled adjustable lens](https://www.trendhunter.com/trends/bio-lens). They are available online for about $900. ## Trend Insights (Trend Hunter) - Score: 3.6/10 - Popularity: 5% | Activity: 95% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Life-Stages](https://www.trendhunter.com/life-stages) > [Boomers](https://www.trendhunter.com/boomers) ## Key Themes ### What Makes This Trend Stand Out - **Adjustable Focus Eyewear:** The trend of adjustable focus eyewear allows wearers to easily customize their focus for optimal vision. - **Disruption in Eyewear Industry:** The innovation of adjustable focus eyewear disrupts the traditional market of fixed prescription lenses by offering a more flexible and personalized solution. - **Enhanced User Experience in Eyewear:** Adjustable focus eyewear provides a seamless and comfortable user experience without the need for multiple lens options or disorienting visual transitions. ### Sectors Adopting This - **Eyewear:** The eyewear industry has an opportunity to embrace adjustable focus technology to provide customers with customizable vision solutions. - **Healthcare:** Adjustable focus eyewear can revolutionize the healthcare industry by offering individuals with vision impairments a more tailored and user-friendly option. - **Technology:** The adjustable focus eyewear industry opens up new possibilities for technological advancements in lens design and manufacturing. ## Related on Trend Hunter - [Transforming Liquid-Lens Sunglasses](https://www.trendhunter.com/trends/32-degrees-north.md) - [Adaptive Autofocus Eyewear](https://www.trendhunter.com/trends/ixi-2.md) - [Autofocus-Providing Eyewear](https://www.trendhunter.com/trends/hightech-autofocus-eyewear.md) - [Spiralled Shape Contact Lenses](https://www.trendhunter.com/trends/spiral-diopter.md) - [Adaptive Reading Sunglasses](https://www.trendhunter.com/trends/32n-sunglasses-by-deep-optics.md) - [Smart Focus Glasses](https://www.trendhunter.com/trends/phantom-journey.md) - [Versatile Eyewear Collections](https://www.trendhunter.com/trends/framery.md) - [Adjustable Tinted Glasses](https://www.trendhunter.com/trends/aura-rx.md) - [Nano Projector Nearsightedness Eyewear](https://www.trendhunter.com/trends/kubota-glass-eyeglasses.md)
