Can that be changed even though there's warranty? since if it's due to wrong prescription or axis out?

I guess having a good optician is important...

it's a must to change for you..

 

[iNETeVO]

it's a must to change for you..

zzzzz...... if cannot? I think the optician would need... its like that for the beginning... after some time you would get used to it...

 

[iNETeVO]

and what are the ways to prevent over correction...

or symptoms during the test to know that it is under power or over corrected?

It's a 100% can if the degree does not suit you...

If you say it this way mean you are accommodating the spec degree and not the spec accommodating you!!

usually at most 3days to 1week at most for new prescript single vision lens to be @ comfort point. if it's still not ok mean it's something wrong.

ok...

so it's still early to tell... since I only continuously wore it for 1 day.. and switched back to old spec
can't help it... need to work and do things... can't tell vision affect my tasks...

But since your degree have increase so you will not be able to switch between new and old pair.

yah... so far I tried for 1 full day and switched back to old spec... it feels blur at first... but within minutes i'm adapted to it...

once put on the new lens... its slightly sharper... since its only 25deg increase

 

[iNETeVO]

question about prescription...

if the degree is exact.. would it cause giddiness or eyestrain?
how about only 25deg or 25 astigmatism lesser? would this slight blurness cause frequent eye strain...

..........
guess i'm considering a new pair of lens...

Thinking of trying Zeiss or Nikon...
wonder which one is better... ?

need to be super clear and good in anti reflection for easing eye strain...

May try the Zeiss lens!!!

if the degree is exact.. would it cause giddiness or eyestrain?
ans: Yes, due to new lens would be slightly different as the lens will be much more shiny especially Half or No Rim Frame

how about only 25deg or 25 astigmatism lesser? would this slight blurness cause frequent eye strain...
ans: Yes, If you are saying looking very far away, or unless your degree have gone up very high......

For astigmatism not only the power but the axis is also very important!! Some ppl are very sensitive to Axis line.

and what are the ways to prevent over correction...

or symptoms during the test to know that it is under power or over corrected?

there isnt any method to prevent over-correction. an optician/optometrist will base an eye examination on ur responses to certain alphabets or numbers. wat makes the difference between a good optician/optometrist from the bad is the ability to interpret a response in various possibilities.

a lot of optician/optometrist are jus going through motions. i.e if u read O as C then this is wat i should do. but this isnt ALWAYS the case. there are many variations to that response and a good optician/optometrist will know how to interpret tat differently to give the most comfortable prescription cos there isn't THE correct prescription.

if ur sensitive enough, u will feel an eye-strain if there is only a -0.25 over correction. as in, u may feel tat something's pulling ur backwards into ur brain. maybe even a throbbing feeling to go with tat.

if ur prescription isnt too high and if u can read without ur glasses, u may even feel more comfortable if u remove ur glasses to read than to wear them to read.

hi bro,

its very interesting that u put out such a definite answer to these questions cos i don experience these symptoms all the time.

i have tried new glasses with no problems at all and im sure that there are many bros out there who have similar experiences. i think there are no hard and fast rules with regards to a persons' reaction to a new prescription

i believe there isnt THE correct prescription but there is the most comfortable prescription and the best optician/optometrist may not even be able to give anyone THE correct prescription. i always believe tat the optician/optometrist who can give me the most comfortable prescription is the best optician/optometrist

It still might. There are so many other factors that come into play, lens type (very important), incorrect PD etc.

If you use the computer often, you need to take breaks and also speak to the optician attending to you what you mostly use it for. The eye test is a mid distance set-up that may not be the best for your needs.

thanks for the reminding of the question~ [this is not a definite answer to anyone] but this may be also a effect which will happened that i have gone through with sensitive px before... which are more for sensitive eye's ppl...

Hi there

Sorry to interrupt. A little off-topic here.
I have a 2 years old Lindberg Acetanium for sale.
Buzz me if interested. Thanks!

NAH. You are so wrong. If we give patients the prescription that they are most Comfortable with then what for train optometrists?

Many Ah tiong Patients that i see always ask me to give them a lower prescription even when they are seeing 6/9 or worse. This is because of a wrong mindset. Their doctors over in Ah tiong land told them that if a full prescription was given to them, their prescription will increase as the year go by. This is a false perception of the public.

Similarly, If a patient prefers a OVER-corrected prescription, WE CANNOT GIVE IT TO THEM. This is because an over corrected near sighted (myopia) prescription sets of the focusing muscles in the eye and strains it. Research studies have shown that this Strain caused on the muscles is one of the possible factors leading to the development of myopia. This is especially true in young children because of the very active muscle in the eye. This can potentially cause them to be severely myopic in the future. Thats why you must always trust your optometrist on your prescription.

However, human do make errors. That is why our patients response is very important when checking their prescription. you must voice out any discomfort and the optometrist will adjust accordingly. that is why frequent eye checks is required. Most commonly, once a year so potentially blinding diseases can also be detected early.

My glasses are 1100 both eyes but my optcian give me 1000 only bot eyes is that ok?

If the optician gives a wrong prescription what the worse that could happen?


retinal detechment?

 

[iNETeVO]

Thanks for all the response! Looks like we have a number of experts here...

Now wearing my old lens make me feel tired....
wearing the new lens make me slightly giddy...

Won't want to go back to that optician anymore... although the shop offer cheap Seiko Lens....

Need to feel a good optician...

anyway some more questions:

Can lens be migrated from one frame to another?
If frame A is bigger size than frame B... can cut and migrate frame A lens to fit frame B?

aldric12, what is axis line??

I often hear people said that Zeiss is the best lens... even better than nikon? Why is it so? Better in terms of what? Clarity (reflection)? durability? sharpness? or special features?

If he prescribe 1000 means your degree is 1000 la. How u Noe it's 1100. Ur prescription is given based on the best corrected line you see. And for cases like you. I have seen many. Most have best vision of less than 6/6. Around 6/9 to 6/7.5. To improve to 6/6 require 100 degree or more. So I will not prescribe that extra 100 degrees. Cos it will be too strong. Get it?

Usually to adapt to a new prescription will take about 2-3 days. DONOT interchange between new and old prescription cos will take longer to adapt. TRY IT for a week. IF you still feel headache 1 week later go back to the optometrist/optician and request for a change. MOST LIKELY the prescription is wrong.

Lenses can be cut to fit the new frame but the PD (distance between both eyes) MAY not match in some cases but the lenses can still be worn. FOR lower prescription there will be little effect. but for high prescription it will be harder to adapt because of the LARGER amount of PRISMATIC EFFECTS(GOOGLE IT).

AXIS line is where ur astigmatism orientates or lie. its the angle where the astigmatism is.

Carl Zeiss lenses are superior in terms of the optical quality. which means the quality of images transmitted. and also their COATING. Go to zeiss website and read about their lenses. can find more information.

 

[iNETeVO]

For 1.67... 600 degree... what's the price range for Zeiss? how about Nikon?

Are they fully aspherical (flat at the front)?... perhaps that's the trend... though it's ugly...
