Subject of the invention:
Improving the fit of glasses

Eyeglass wearers often suffer from poorly fitted visual aids. She slips forward what

1. does not look good to the wearer,

2. is very uncomfortable when sweating,

3. Field of vision and visual acuity deteriorated

4. obstructive during sporting activity and

5. cannot be corrected when operated with both hands or when hands are dirty.

The previous options for correcting these deficiencies are in in most cases not effective. For example, attaching pads to the glasses (nose area), attaching of more or less hard foam on the connecting bridge of the glasses, which lies on the nose, tight fitting the artificial horn bracket on the head, which leads to headaches in the long run - all of this is unsatisfactory. The low coefficient of friction between synthetic horn fabric and hair / skin or damp skin does not produce a firm, secure fit. With glasses temples made of metal, plastic or plastic-coated fflet.all hangers a better fit can sometimes be achieved by tight guidance around the auricle. But if there is moisture on the surface of the skin the coefficient of friction decreases and the glasses slip, in particular with jerky movements, inevitably forward. How often do you observe that people wearing glasses are constantly using their visual aids have to push back into the original position, which is very annoying and is annoying.

This annoyance can be remedied by providing an appropriate solution Piece of soft rubber tubing over the ear part of the temple is pulled; up to approx. 5 cm are sufficient in length. By don soft rubber hose will have such a high coefficient of friction too Skin or hair creates that prevents the glasses from slipping will. Skin secretions, uj ^ e, F.eu ^ hti gk ei t, sweat and others

Urganic substances influence the coefficient of friction
almost not. Unfortunately it is inevitable that organic
Skin secretions (fat, acetic acid, etc.) into the elastomer
diffuse, but the adhesive effect remains.

In this case, it is most convenient, since ^r · hose piece if necessary

to renew. In general one should switch to

Take about 3 months. The cost of a new piece of tubing

are minimal.

The rubber hose should have a high level of softness, since one

is very sensitive behind the ears. Shore hardness A about 15.

Rubber hose made of vulcanized para rubber (polyisoprene)

brings sufficient elasticity, toughness and elongation (> B00 $)

with; but synthetic rubbers are also suitable as a base, which must be ulcanized, but with appropriate softness and extensibility.

The tolerance on the skin is. good to excellent.

In addition uon Addi ti v / s, also introduction ärbungen, has the

Maintaining the properties mentioned must be respected. the

Additiue must not cause skin irritation.

Rubber , colored light - yellowish - brownish, made of natural rubber,

is ideally suited for this application, in particular also because of its color.

The inner diameter of the hose depends on the

Diameter of the bracket. In general, the mentioned Properties of the hose 3-4 mm will be sufficient for

Plastic or horn hanger to fit. For children's glasses or

modern forms with relative; thin metal brackets of 1-2 mm

The diameter must correspond to the inner diameter of the hose c be chosen smaller.

The wall thickness of the tube should be around 1.5 - 2 mm.

A wall thickness of less than 1.3 mm can cause pressure points on the head.

The hose can be pulled on without any problems; often that is enough

Air humidity of the breath by blowing through the tube, Otherwise, water is allowed to run through, because on this

Wise, this kind of winding always works, unless you have it

The chosen diameter of the hose is too small.
