✔ 最佳答案
理論上無論近視度數有幾深都唔會盲不如我講下所謂既度數有咩意義
近視度數其實係指隻眼最遠可以睇清幾遠既野(維持隻眼應該有既清楚度)
果個最遠既地方咁far point
公式係咁
Far point = 1 / [近視度數 / 100]
單位係米
姐係0度 = 無限遠
50度= 1 / [50 / 100] = 2米
100度 = 1米
200度 = 50厘米...
所以1000度 = 10厘米
2000度= 5厘米
去到10000度(=.=||)都仲有1厘米...
類似數學上limit既概念...
而且近視同眼球長度有關
所以近視應該有上限
所以應該係唔會盲既
但係近視深會令視網膜易脫落
呢個會致盲

所以，你個朋友o既近視眼
其實都唔知係咪天生
不過眼球過長的話，斷估都唔會係佢用手整長
所以多數都係天生

１００００度近視其實唔需要帶眼鏡
因為可以正常咁睇野
你可能比你朋友呃呀！

1000 or 10000?
1000 is very serious short-sight,I cannot imagine how is 10000.He/She shouldn't see anything even with glasses.
People with such degree of short-sight usually inherit from their parents.
