CRT lens for kids

Both my 2 kids are taking CRT now.

My son started at 3rd grade, now he's a Junior. So 8 yrs experience on CRT. He takes on alternative days. Every couple of years, I took him to different eye doctors for 2nd opinion. 

One doctor said the eyeball can be flat after CRT pressed. The flexibility to turn back can be weak after years of use. 

Last year, we had him checked by a Harvard graduate whose expertise is on laser. His opinion is interesting:

Cons:
1. CRT is difficult to get populate as the cost. It's very expensive - here $2500 for the 1st year package, then $500 for the replacement. No insurance coverage. Well, Chinese family is willing to pay higher cost to do anything good for kids :-)

2. CRT needs the patience/persistence to take on/off every day. It's difficult for young kids to keep the lens clean. Mom has to provide help every day, year by year.

Pros:
1. CRT has existed for many years, the theory is correct and the lens has improved a lot over the years. Not like laser, it's doubtful now.

2. CRT has no age limit. Actually, the younger the better for the growing kids. Once the growth is slow or stable, the eye problem won't get worse. My son had 100 increase every year from the 1st grade till 200 @ 2nd grade. After 8yrs of CRT, it's still 200.

3. CRT can be life-time if kids can build up the persistence. Does he need to change to soft lens after 16yr old? Not necessary. College students may have less sleep or sleep late night. This may have impact.

4. Eye usage will be less and less after college. He doesn't need to look at white-board daily at work.

As for laser on my hu*****and (40+ year old), the doctor doesn't suggest him to take it because he is in the development period of "lao3 hua1".

As for the Vitamin pills for eyes, the doctor doesn't recommend either. The doctor is ABC whose parents from Taiwan. Lots of Taiwan-nese enjoy Centrum vitamin pills. Now daily Vitamin is also in doubt as it's a medicine pill not natural.

I tried to avoid CRT for my daughter, especially she is good at sports. She started 100-200 lens @ 6th grade. It worsen @ 7th grade, so we decided to have CRT. 

For me, I used to take on/off for my son for last 7 years. Cleaning is also my daily routine in the busy morning. Now both kids take care CRT by themselves. Really appreciate it!
