Description

Light glasses for high-myopia people

Technical Field

The utility model relates to a glasses field of making, concretely relates to light-duty glasses for high myopia crowd.

Background

Relevant data show that myopia incidence will rise worldwide, from 28% (20 billion) of the global population in 2010 to nearly 50% (50 billion) in 2050. Thus, the prevalence of high myopia is also likely to increase from 4% (2.77 billion) in 2010 to nearly 10% (10 billion) in 2050.

Myopia refers to a condition where viewing at distance is blurred, but closer objects are seen more clearly. Myopic power is expressed in diopters (D). Most myopes are below-6.00D. Conventionally, if the eye requires a corrective lens power of-6.0 or more, it is considered highly myopic.

The most common method of treating myopia is by wearing corrective or contact lenses that refocus the light on the retina. Contact lenses can cause complications (e.g., dry eye, corneal deformity, immune response, infection), but may be advantageous for activities that do not wear lenses (e.g., certain sports).

Refractive surgery is an option, and once vision problems develop in the eye, the head usually comes out at age 20. The most common refractive procedures are laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK). Both alter the shape of the cornea, allowing light to better focus on the retina.

LASIK removes tissue from the inner layer of the cornea. To do this, a thin outer corneal surface is cut and then folded over to expose the inner cornea. Laser removal of a certain amount of tissue remodels the cornea, and the flap is then put back in place for healing. The corrective effect of LASIK surgery is limited by the amount of corneal tissue that can be safely removed.

PRK also removes a layer of corneal tissue, but does not create a surface flap. Instead, corneal surface cells are removed prior to laser surgery. Like LASIK surgery, the limitation of PRK is how much tissue can be safely removed.

Although refractive surgery is mature, many people are reluctant to do it because of concerns about postoperative risks and health problems, or are unable to do it because of health problems such as age, thin cornea, etc.

My target population is highly myopic (6 to 9 diopters), unable or not wanting to cure vision through surgery, most of the time wearing glasses. According to the preliminary investigation of the inventor, the weight of the common material glasses with diopter of-6.0 exceeds 20 g. Generally, a higher diopter lens weighs more. However, due to materials, lens power, lens size, lens refractive index, etc., high-vision spectacles weigh between 20 grams and 40 grams. While most high power lenses weigh more than 20 grams. It is worth noting that the weight of conventional lenses has been found to be uncomfortable for the nose and ears, let alone with a heavier pair of high diopter eyeglasses.

Therefore, based on the above, reducing the weight of the glasses with high myopia and alleviating the discomfort caused by the glasses pressing on the human body are the urgent technical problems to be solved. Therefore, the application provides a light-duty glasses for high myopia crowd, through the selection to the glasses material and the design of glasses structure, when effectively reducing high glasses weight, further slows down the oppression sense of high glasses to the human bridge of the nose, and then effectively solves the problem and the defect that prior art exists.
