With a Mast antenna - AM-D120-HA135-RA - the product meets MIL- standards, has a payload of 30Kg, a mast lifting time of fewer than 5 minutes, and can be performed with a Control box or hand-held controller. The product also includes an Emergency Button and an automatic stop system. Furthermore, the product MJ-05M06G03A-NF - one of the most popular today - is 1.5kg light, has high features, and is simple to install, with frequency levels ranging from 500MHz to 6GHz, 3DBi. Not only that, but for many years we have been a supplier of FT-7500 - Marine antenna for the region.
一般指的近視與遠視度數,是指屈光系統的整體度數,調理能力則是另外一個面相。可是,老花眼鏡的度數倒是調理能力的退化度數與現存屈光度數的加總,是以,度數選擇並不是人人溝通,例如一名60歲長者的調理能力退化300度,看近物時,需賜與正300度的鏡片改正;可是,若他的屈光為近視300度(需要負300度的鏡片改正),則加總後為零度,亦即近視300度的患者,在60歲時不需要額外的鏡片便可看清晰書報文字。
年過40歲以後,很多民眾都有看書報、手機越看越恍惚的困擾,思疑豈非是本身老花?為讓民眾更進一步認識老花眼,和若何選擇老花眼鏡,食物藥物治理署(下稱食藥署)約請台北榮民總病院眼科部主治醫師范乃文為民眾進一步申明。
范乃文指出,一般老花眼鏡為單焦鏡片,只有看近時才需配戴。但如果有近視或遠視的人,就需要兩副眼鏡瓜代利用。為了輕易,有些近視者會將看遠的鏡片下降一點度數,以保存一些度數來看近。另外,市情上也有漸近式多焦老花眼鏡,這是在鏡片中心與下方做成分歧度數,形成一片多焦,也就是擁有一副多用的功能,但必需克服適應上的問題。
范乃文指出,人類的眼睛具有高度邃密的屈光系統,能將外在影像清楚映入眼簾。傑出的屈光系統,可以將影像清晰傳送到視網膜,再由視神經傳輸到腦部加以解讀。此屈光系統必須要清亮非常、可透光,還要具有調理功能,當物體越近,調理能力要越強,才能讓物體顛末屈光系統的核心,落在視網膜上。屈光系統的調理能力到了40歲今後,會隨年數增進逐步退化,使得看近時(如浏覽書報)的目力遭到影響。
The FT-RF main profession in R&D and manufacturing of antenna, be alongside of to be subjected to any OEM of nation and ODM, provide the product of the best quality and let the sale has the price of competition ability most , is the target that the FT-RF has been making great effort.除此之外,一般市售的老花眼鏡多為制式度數,可能不合適每一個人,且如有散光等問題,也沒法以制式老花眼鏡加以改正,看久可能會產生疲憊感。
食藥署提醒,老花眼鏡應諮詢專業人士驗配,除老花度數,還要權衡有沒有近視、遠視、閃光?是不是適合具有多焦的功能?周全的評估與配製,才能讓糊口加倍安閑與便當。
