[0002] More and more people are wearing glasses these days. Wearing glasses can lead to problems such as glasses slipping off and leaving marks on the bridge of the nose. One reason is that the increased thickness of the lenses adds to the weight of the glasses. Another reason is that the ears act as a fulcrum, causing an imbalance in weight between the frame and the temples, which intensifies the pressure of the frame on the bridge of the nose.

[0019] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0020] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of eyeglasses according to one embodiment of the present invention; Figure 2 This is a cross-sectional schematic diagram of the temple and counterweight of one embodiment of the present invention. Figure 3 yes Figure 2 A partial schematic diagram.
[0021] A pair of eyeglasses with a counterweight includes: a frame 1 and temples 2; the temples 2 have a sleeve 3 and a counterweight 4 at their tail ends, the sleeve 3 is fitted onto an ear loop at the tail end of the temple 2, and the counterweight 4 is connected to the tail end of the ear loop. The tail end of the ear loop has a threaded portion 5 and a pressing portion 6. One end of the counterweight 4 has a threaded hole 7 and a connecting hole 8, and an annular step 9 is provided at the junction of the threaded hole 7 and the connecting hole 8. A limiting sleeve 10 is adhered to the annular step 9, and one end of the limiting sleeve 10 has a plurality of annular arrays of limiting... The inner wall of the connecting hole 8 is provided with a protruding ring 12, and one end of the sleeve 3 is provided with a connecting part 13. The outer surface of the connecting part 13 is provided with an annular limiting groove 14. The sleeve 3 and the hanging ear are simultaneously inserted into the counterweight 4. The limiting groove 14 on the connecting part 13 cooperates with the protruding ring 12 on the connecting hole 8. The threaded part 5 of the hanging ear cooperates with the threaded hole 7. The pressing part 6 drives the limiting part 11 on the limiting sleeve 10 to abut against the inner wall of the connecting part 13. The hanging ear is connected to the counterweight 4 and limits the sleeve 3.
[0022] The cross-section of the pressing part 6 is an isosceles trapezoid; one end of the limiting sleeve 10 is provided with three ring array limiting parts 11, which can be bent outward; one end of the limiting part 11 is provided with a protrusion 15; the diameter of the connecting hole 8 is larger than the diameter of the threaded hole 7, and the depth of the connecting hole 8 is equal to the length of the pressing part 6.
[0023] In summary, the counterweight 4 fixed to the end of the temple 2 of this invention balances the frame 1 and the end of the temple 2, which can prevent the glasses from slipping and reduce the pressure of the glasses on the bridge of the nose, thereby improving the wearing comfort.
[0024] The specific matching method for counterweights:
[0025] 1. Estimation of total basic counterweight: Reference for front and rear weight ratio
[0026] It is generally recommended that the ratio of the weight of the front half to the total weight of the temples (including counterweights) be controlled between 1.2:1 and 1.5:1 (that is, the weight of the front half is slightly greater than the total weight of the temples, but the difference should not be too large).
[0027] Formula reference: Additional weight required for a single temple ≈ (Total weight of the front half ÷ 2) - Original weight of a single temple
[0028] Example: The total weight of the front part is 24g (12g on each side), and the original weight of a single temple is 5g. Therefore, the weight required for a single temple is approximately 12g - 5g = 7g (a total of 14g of weight is required for both temples).
[0029] Special case: The front part of children's glasses is usually lighter (10-15g), and the weight of the temples needs to be even lighter (2-3g per eye) to avoid pressure behind the ears.
[0030] 2. Counterweight Position: Precisely Adjust the Center of Gravity
[0031] The position of the counterweight is more critical than its total weight, as different positions have significantly different effects on the center of gravity.
[0032] The end of the temple (most common): has the strongest effect on shifting the center of gravity backward, and is suitable for situations where the front half is obviously heavier;
[0033] Middle of the temples (near the back of the ear): Moderate effect, can enhance the fit behind the ear, suitable for scenarios with slight forward tilt or when an optimized fit is needed;
[0034] Front of the temple (near the hinge): The effect is weaker, mainly used for fine-tuning the body balance and avoiding excessive weight that could cause the glasses to tilt backward.
[0035] 3. Try-on and optimization: The core step of personalized adjustment
[0036] After theoretical estimation, it needs to be verified through trial wearing. Pay special attention to the following feedback:
[0037] Does the glasses slide down when you lower your head, or is there a noticeable pressure on the bridge of your nose? If so, you need to add weight or adjust it to the end.
[0038] Does it tilt backward: When tilting your head back, do your glasses slide backward, and do you feel tightness behind your ears? If so, you need to reduce the weight or adjust it to the middle.
[0039] Long-term comfort: After wearing it for 1-2 hours, do you experience soreness in the bridge of your nose or behind your ears? If you experience soreness in the bridge of your nose, you need to increase the weight; if you experience soreness behind your ears, you need to decrease the weight.
[0040] Common misconception: Avoid the "counterweight as a panacea" theory.
[0041] Not all glasses need weighting: if the frame itself is lightweight (such as pure titanium + high refractive index lenses) and the weight is balanced from front to back, no additional weighting is needed;
[0042] More weight is not always better: Excessive weight can lead to fatigue of the temples (especially acetate temples), which may deform over time, and excessive pressure behind the ears can cause headaches.
[0043] It is necessary to combine the elastic design of the temples: elastic temples (such as spring temples) can enhance stability through their own tension, and the weight can be reduced appropriately; rigid temples need to rely on weight to improve the fit.
[0044] Summarize
[0045] Matching the weight of the counterweights to the overall weight of the frame is a process of "dynamic balancing": using the weight of the front half as a baseline, combined with the original weight of the temples and the user's physiological characteristics, the center of gravity is stabilized in the balance zone through a three-step process of "estimating the total weight → adjusting the position → trying on and optimizing". The core goal is not "adding weight", but "optimizing the distribution" - ensuring that every part of the weight serves comfort and stability, rather than simply being added together.
