未有近視都唔可以掉以輕心!
點解小朋友6歲前要有遠視?
小朋友在3~4歲的時候,大概還會有150度以下的遠視。隨着眼球發育變長,遠視度數會越來越少。一直到16-18歲左右,眼球發展比較成熟時,度數才會穩定下來。尤其在6至12歲,眼球發育速度最快的階段,如果沒有保持著一定程度的遠視,度數就有可能快速增加變成近視。
假如小朋友6歲前已經沒有遠視,又沒有積極治療,每年加深速度可高達100度以上。如果小學一年級就已經有近視,等到小學畢業,按推算下會有600、700度左右的近視。阿托品眼藥水Atropine為目前
唯一有效預防近視的藥物。
4至9歲,沒有近視兒童
155名接受安慰劑
160名接受
0.05%阿托品
0.05%阿托品
每日滴一滴安慰劑兒童
兩年內出現近視比率高達53%2
每日滴一滴阿托品Atropine兒童
兩年內出現近視比率只有28%2
咁我本身有近視滴唔滴得阿托品Atropine眼藥水㗎?
緊係得!同埋你都快啲換咗你副普通近視眼鏡,如果唔係度數會愈嚟愈深!
咁點算呀?!
勿再戴普通近視眼鏡!
普通近視眼鏡主要功能是矯正中央視力,結構設計較為簡單。當在近距離用眼情況下(33厘米內),普通近視眼鏡會將周邊光線聚焦在視網膜後,形成較大程度的遠視離焦,從而可令近視加深。對於小朋友在近視加深的高峰期,佩戴普通近視眼鏡對近視的控制或預防沒有太大幫助,因此近視控制眼鏡(離焦鏡)才能更有效預防及控制近視加深。最有效的近視控制方案是混合治療
6至14歲是近視加深的高峰期
6-14歲是近視加深的高峰期,把握時機關注眼睛健康,可減慢近視加深速度。 隨著近視加深,有機會會演變成深近視,會大大增加患上嚴重眼疾的機會。近視800度以上的人患上嚴重眼疾的風險比正常人高,例如視網膜脫落,白內障,青光眼,黄班點病變等。激光矯視都無法減低風險,所以絕對要及早做好近視防控,防患未然。
