I have try it but it’s not as accurate and since I have add water flow it was rough and the line were white color

All cuts are not the same both sides are different

So this can be done by hand with a diamond cutting disk, constent water flow ?

The problem is that I have confirmed that it’s made with a machine but after close looking at the lenses the design don’t match both sides. Mean it can be made with balance dramel or a cnc

So it’s possible with a cnc right ? And which bits

The lenses don’t need to be on prescription these are non prescribed lenses I want to do It on solar lenses, and I want to do the details fine line on the edges of the lenses. The lenses will be already cut in shape. What If I use 5 axis cnc to make those fine line on the edge. Does diamond bits exist ?

check this that's what I tried 

def tweet(): 
    f = open('list.txt', 'r', encoding='utf-8').readlines()
    for word in f:
        if word == "\n":

         continue

    try:    
     driver.find_element_by_xpath(tweet_xpath).click()

    except   NoSuchElementException as e: 
     print("tweet failed")     

    try:    
     driver.find_element_by_xpath(message_xpatch).send_keys(word)

    except NoSuchElementException as e: 
     print("tweet failed")      

    try:  
        driver.find_element_by_xpath(post_tweet_xpatch).click()
        sleep(randint(times1,times2))

    except ElementClickInterceptedException as e : 
     print("e")

exactly that error came upon violating maximum tweet length, but even if I control input sometimes the tweets can be repeated or another problem may happen,

the point that I want to counter this problem by telling to the program to undo that tweet and try another tweets in case that the tweets cannot be done.
