Topical Balm for Dry Eye Relief via Tear Stimulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for dry eye syndrome, such as artificial tears and invasive procedures, are inconvenient and carry risks of infection, as they require frequent application of medications directly into the eyes or involve invasive methods.
Innovation Solution
A specially formulated balm applied to the skin adjacent to the eye, containing caffeine and menthol, which stimulates tear production by the lacrimal glands, eliminating the need for direct eye medication and invasive procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If artificial tears are applied directly into the eye, then dry eye symptoms are relieved, but the risk of infection increases and convenience decreases
Solution Approach 1:
The patent uses the skin adjacent to the eye as an intermediary site for applying the balm, which then delivers active ingredients (caffeine and menthol) to stimulate tear production indirectly. This mediator approach eliminates direct contact between medication and the eye, reducing infection risk while maintaining treatment effectiveness through transdermal absorption and local stimulation of lacrimal glands.
Solution Approach 2:
The balm formulation with caffeine and menthol stimulates the body's natural tear production mechanism, allowing the eyes to self-lubricate using their own tear film. This self-service approach eliminates the need for repeated external applications, improving convenience and reducing the risk associated with frequent eye drop use.
2Duration of action of moving object
If eye drop bottles are carried and used frequently, then dry eye relief is maintained, but user convenience and hygiene are compromised
Solution Approach 1:
The balm is applied in advance to the skin adjacent to the eye, where it continuously stimulates tear production over an extended period. This preliminary action creates a sustained effect that eliminates the need for frequent reapplication of eye drops, allowing users to leave the treatment site without carrying bottles or worrying about hygiene during daily activities.
3Reliability
If invasive procedures like lacrimal plugs are used, then tear retention is improved, but patient comfort and acceptance deteriorate
Solution Approach 1:
The patent replaces the mechanical invasive approach of lacrimal plugs with a chemical/biological approach using caffeine and menthol to stimulate natural tear production. This substitution eliminates the need for physical insertion into eye ducts, dramatically improving patient comfort and acceptance while achieving the goal of increased tear availability through physiological stimulation rather than mechanical blockage.
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
The balm enhances natural tear production, reducing the risk of infection and the need for constant eye drop applications or humidifying eyewear, providing effective dry eye relief without direct eye contact.
Implementation Method 1
the balm, so positioned, acts to energize tear production by the eyes and constant communication of natural liquid tears to the surface of the eyes

AI summary
A balm mixture is provided for treating dry eyes. The balm mixture is applied from a container to the skin of the user adjacent their lower eyelid. The balm mixture includes a carrier portion and an active ingredient portion which will cause tears to form in the eye of a user adjacent the application thereof, thereby alleviating a dry eye condition.
