Description

隱形眼鏡產品contact lens products

本發明是有關於一種隱形眼鏡產品，且特別是有關於一種可以預防近視或控制近視進展的隱形眼鏡產品。The present invention relates to a contact lens product, and in particular to a contact lens product that can prevent myopia or control the progression of myopia.

根據世界衛生組織（WHO）資料顯示世界各國近視盛行率介於8%至62%之間，然而在臺灣的調查發現18歲以下青少年與兒童的近視率高達85%，其近視發生的比率明顯超越其他國家，其中原因很可能是由於近年來高度發展的3C電子裝置，使幼童的眼睛過早接受不當刺激與造成用眼過度，目前研究顯示，一但幼童罹患早發性近視，其後會以一定的速度增加近視度數，研究另指出，得到近視的年齡越低，日後演變成高度近視(大於等於6.0 D)的機率越高，而高度近視患者更可能引發視網膜剝離、青光眼等嚴重的併發症。因此，倘若能夠於察覺幼童患有假性近視時即進行控制與減緩近視，則可有效避免假性近視轉變為近視，進而預防高度近視的發生。According to data from the World Health Organization (WHO), the prevalence of myopia in various countries around the world ranges from 8% to 62%. However, a survey in Taiwan found that the myopia rate among adolescents and children under the age of 18 is as high as 85%, and the rate of myopia is significantly higher than In other countries, the reason is probably due to the highly developed 3C electronic devices in recent years, which expose young children’s eyes to premature stimulation and excessive eye use. Current research shows that once young children suffer from early-onset myopia, they will later develop myopia. Myopia will increase at a certain rate. Research also points out that the younger the age at which myopia occurs, the higher the chance of developing high myopia (greater than or equal to 6.0 D) in the future, and patients with high myopia are more likely to develop severe myopia such as retinal detachment and glaucoma. Complications. Therefore, if myopia can be controlled and slowed down as soon as it is discovered that a young child has pseudomyopia, it can effectively prevent pseudomyopia from turning into myopia, thereby preventing the occurrence of high myopia.

近視的主要成因是眼球光學構造的變異所造成，其中形成光學成像主要藉由眼球的角膜、水晶體與眼球長度等因子所影響，正常人的眼睛可以將影像正確聚焦於視網膜上而得到清晰的影像，近視患者則可能由於角膜與水晶體的屈光度過強(屈光性近視)或是眼球軸距過長(軸性近視)而導致影像聚焦於視網膜之前，呈現影像模糊的近視症狀。幼兒童的近視症狀可分為近視與假性近視，其中近視是屬於眼球軸距過長的情形，無法藉由矯正而恢復，但若為假性近視，則為睫狀肌過度用力的短暫近視症狀，屬於可矯正的近視症狀。臨床上有許多用於矯正兒童假性近視的方式，主要有角膜塑型鏡與長效型散瞳劑等方式，但其中的角膜塑型鏡易造成高度外部壓力而使配戴者產生不適感，而一般單獨使用長效型散瞳劑須要較高濃度的劑量方能發揮矯正近視的效用，但也相對提高產生藥物副作用的機率。The main cause of myopia is the variation of the optical structure of the eyeball. The formation of optical imaging is mainly affected by factors such as the cornea, crystalline lens, and length of the eyeball. Normal people's eyes can correctly focus the image on the retina to obtain a clear image. Myopia patients may suffer from myopia symptoms in which the image is focused in front of the retina due to the excessive refractive power of the cornea and crystalline lens (refractive myopia) or the excessively long axial distance of the eyeball (axial myopia). Myopia symptoms in young children can be divided into myopia and pseudomyopia. Myopia is a condition in which the axial distance of the eyeball is too long and cannot be restored through correction. However, pseudomyopia is a short-term myopia caused by excessive exertion of the ciliary muscles. Symptoms are correctable symptoms of myopia. Clinically, there are many ways to correct pseudomyopia in children, mainly including orthokeratology lenses and long-acting mydriatic agents. However, the orthokeratology lenses can easily cause high external pressure and cause discomfort to the wearer. , and long-acting mydriatic agents generally require a higher concentration of doses to correct myopia when used alone, but this also increases the probability of drug side effects.
