Corrective Lens Attachment for Visors and Goggles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for vision correction, such as glasses and contact lenses, are inconvenient for use in activities like driving, cycling, or wearing protective gear, as they obstruct the field of view and require constant wear.
Innovation Solution
A vision correction lens attachment mechanism that supports a primary corrective lens with adjustable focal points and peripheral lenses, attachable to vehicle visors, helmets, or goggles, allowing for adjustable positioning and angle settings to optimize vision correction without obstructing the view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glasses or contact lenses are worn for vision correction, then vision correction is achieved, but the field of view is obstructed and constant wear is required
Solution Approach 1:
The patent extracts the corrective lens from the traditional eyewear form and relocates it to a separate attachment mechanism that can be mounted on vehicle visors, helmets, or goggles. This allows the corrective function to be separated from the primary protective or activity equipment, enabling vision correction without wearing traditional glasses or contact lenses that obstruct the field of view.
Solution Approach 2:
The patent introduces an intermediary attachment mechanism that serves as a bridge between the corrective lens and the primary equipment (visor, helmet, or goggle). This intermediary structure allows the lens to be positioned optimally for vision correction while being supported by existing equipment, rather than requiring direct contact with the user's face as traditional eyewear does.
2Reliability
If traditional glasses are worn, then vision correction is provided, but they require constant wear and are inconvenient for activities like driving or cycling
Solution Approach 1:
The patent creates a universal attachment mechanism that can be mounted on multiple types of protective gear and equipment including vehicle visors, helmets, and goggles. This single system provides vision correction across multiple activities and contexts, replacing the need for separate eyewear solutions for different activities.
Solution Approach 2:
The patent incorporates adjustable mounting mechanisms that allow the corrective lens to be dynamically positioned and repositioned according to different activities and user needs. The lens can be adjusted to accommodate different head positions, activity requirements, and optical needs, providing adaptability that rigid traditional eyewear cannot achieve.
3Device complexity
If a fixed focal length lens is used, then the lens structure is simple, but it cannot accommodate different focal lengths for various tasks
Solution Approach 1:
The patent implements a dynamic lens system where the focal length can be adjusted based on different tasks and driving conditions. The mounting mechanism allows the lens to be repositioned to change its effective focal point, enabling the same physical lens to serve multiple optical functions for different activities such as distant driving, dashboard monitoring, and peripheral awareness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables clear and adjustable vision correction for both central and peripheral vision, accommodating different focal lengths for various tasks, such as driving and observing dashboard or rear-view mirrors, without the need for glasses or contact lenses.
Implementation Method 1
The corrective lens may have curvature having a focal point substantially at the eyes of the user in use
Implementation Method 2
The corrective lens may be a prescription lens having corrective geometry (such as one having a spherical, cylindrical or axial component), either integrally formed or applied by way of an adhesive overlay

AI summary
A vision correctional lens attachment has an attachment mechanism supporting a primary corrective lens vertically thereunderneath. The attachment mechanism is attachable to hold the primary lens a distance away from the eyes of the user for correction vision ahead therethrough. The present attachment has various applications, including for attachment to vehicle visors, helmets, goggles (such as ski goggles, scuba masks) and the like for correction of vision without having to wear glasses or contact lenses.
