Description

[0001] 1. The invention relates to adaptive fashion glasses with universal vision correction. These glasses include a liquid lens, astigmatism correction, a blue light filter, and UV protection. All components are integrated into a high-quality design.

[0002] 2. Current technology shows that existing eyeglasses require fitting by an ophthalmologist. These eyeglasses are only usable for a specific user. If the user's vision changes, they must purchase new eyeglasses. This incurs high costs and is environmentally harmful.

[0003] 3. The invention is based on the objective of creating a universal pair of glasses. These glasses should be able to correct all visual impairments. They must be self-adjustable. Several users should be able to use the same glasses.

[0004] 4. This challenge is solved through an innovative combination. The glasses combine an adaptive liquid lens with a rotating astigmatism correction ring. A high-quality fashion design makes the glasses suitable for everyday wear. The integration of state-of-the-art technology allows for both manual and automatic adjustment.

[0005] 5. The invention offers numerous advantages. No visits to the ophthalmologist are necessary. The glasses are multi-user capable. They allow for lifelong use even with changing vision. The user adjusts the glasses immediately.

[0006] 6. The adaptive liquid lens, reference numeral 1, contains an optical silicone oil. This oil is located between two flexible polycarbonate membranes, each 0.3 mm thick. The oil has a refractive index of n=1.5. By rotating the adjustment mechanism, reference numeral 3, a precision piston moves forward or backward. This movement changes the volume of liquid in the lens chamber, causing the membrane to bulge outward or inward accordingly. This achieves a diopter adjustment from -6 to +4. The adjustment is made in precise 0.25 increments. The user rotates the adjustment wheel while looking at an eye chart or text, adjusting until optimal focus is achieved. This is done entirely without an ophthalmological examination.

[0007] 7. The astigmatism correction ring, reference number 4, is a separate optical element. This ring has a toric surface for cylinder correction. It surrounds each adaptive lens and can be rotated independently from 0° to 180°. Detents every 5° allow for precise adjustment. The user adjusts the ring themselves by looking at a special astigmatism test chart. They rotate the ring slowly until distortions and blurring disappear. Markings on the ring indicate the current degree setting. This adjustment is also performed entirely without an ophthalmologist.

[0008] 8. The fashion eyeglass frame with reference number 2 is made of high-quality acetate. This material is hypoallergenic and sustainable. The frame invisibly integrates all technical components. The touch sensor with reference number 5 is located in the bridge area above the nose. When the user touches this area, various functions are activated. A Bluetooth connection to the smartphone app is established. Switching between different saved user profiles is possible. Switching between manual and automatic settings is achieved by touching and holding the sensor. A small LED indicator shows the active mode.

[0009] 9. The integrated AI system is based on an ESP32 microcontroller. This processor uses TensorFlow Lite for edge computing directly in the glasses. A time-of-flight (ToF) sensor continuously measures the viewing distance. The measurement range extends from 5 cm to 5 m. This data is processed in real time.

[0010] 10. The AI ​​functionality is highly advanced. Automatic diopter adjustment takes place in just 0.5 seconds. The system uses machine learning to recognize usage scenarios. It distinguishes between reading, computer work, distance vision, smartphone use, and driving. The wireless connection to the app is established via energy-saving radio technology such as Bluetooth Low Energy. The system is powered by a replaceable coin cell battery, such as a CR2032, and allows for 72 hours of continuous operation.

[0011] 11. The accompanying smartphone app significantly expands the functionality. It allows the management of up to 10 different user profiles. The AI ​​system learns each user's personal vision habits. Health data can be exported. Firmware updates are performed wirelessly over-the-air.

[0012] 12. The invention comprises two embodiments. The manual version operates via a rotary dial and ring without a power supply. The automatic version uses AI-supported adjustment via an app. Both versions can be used independently or in combination. This guarantees functionality in all situations.

[0013] The invention relates to adaptive fashion glasses with a liquid lens for stepless adjustment of the visual acuity from -6 to +4 diopters. They feature an integrated astigmatism correction ring (0-180°) that, for the first time, enables variable cylinder correction without the need for an ophthalmologist. The glasses are multi-user capable and offer both manual adjustment via dials and optional AI control via a smartphone app. Self-adjustment is performed by the user by looking at an eye chart. No ophthalmological fitting is required.
