i need help with optics.
i just got nikon seemax optics, have isues with it. gets scratches super easily.
regretted it big time.

price is not of a concern at all, literally.
requirements.
1) minimal chromatic abberation
2) ideally maximium corner to corner sharpness.
3) NO color shift.
4) weight of optics not an issue.

i have tried nikon seemax, essilor and corning.
i tried carl zeiss, the shop kept getting my focal eye distance wrong even after 3 attempts.


my eyes.
L-9.5, R-8.25, distance 64.5mm


i am basically a photographer with better than perfect vision when corrected. very super anal of color shift.

corning/glass tends to be yellowish,
essilor/plastics tends to be reddish
nikon, very neutral which is good.
all the other 'inhouse' are either purplish and reddish.

so far optically nikon seemax is the best, but at this rate, i probably have to change every 3 months, this is officially my 2nd pair of seemax, i literally just kept my frame and just change the lens.

reason why it gets scratched is because of the camera viewfinder.

i cant possibly change my seemax every 3 months cant i?

Anyone knows where can I find Oliver Peoples frame in SG?

The Eye Place and Kwong Shin Optical.

From what i see.. your case is very difficult to please. Not implying you are troublesome.. its possible to have minimal aberrations with certain type of lens material and good optics from corner to corner. but i wonder why u need good corner to corner optics when our focus is very much lesser than the lens height and width itself.

your issue is ANATOMICALLY AND PHYSIOLOGICALLY IMPOSSIBLE for the colour shift issue. For nikon lenses i agree that when worn have a significantly sharper image for myself. with your "Degree" so high, it can be the reason why you are experiencing all the aberrations and nikon being one of the lenses with the best AR coating, solves most of the "problems". Another way, try making a change to contact lenses.

From a scientific point of view.
2cents worth from an optom slogging his way out of NS.

JUST A QUESTION.

MAY I KNOW YOUR VISUAL ACUITY? with that kind of power, its kind of rare to even have 6/6 vision unless over corrected.

ah, what i meant was glass is also an option, it doesnt have to be plastic.

i tried contact lenses. it isnt sharp.
corning lenses are sharper than nikon, BUT it only has a 20 degree view for sharpness. beyound that it feels like the degree has shifted -/+3.0
the corning i used was 1.9 index, glass w/ gold coating.
at least with nikon, i get almost 90 degrees of perfect sharpness. how i wish nikon would make a ED glass version of seemax. seemax has the lowest CA i have ever experienced.

from what i remember, i am 2 steps higher than perfect vision, just 1 sbort of eagle's eyes.

and because of this, noone wants to do lasik for me.

 

[warhunter]

Just like to know I just did lasik and i have 6/6 vision. My job requires me to face at least 10 hours a day in front of the pc.

Is there any non degree lenses with properties or coating that really can shield against pc screen rays? Or is it marketing gimmicks?

one word. GIMMICKS.
no scientific proof as of now.

 

[warhunter]

If you are facing computer for long hours, you will probably get computer vision syndrome (eyestrain) more than the harm that you will get from radiation from the screen.

Even though you had lasik done, there may still be slight degree in your eyes, maybe slight myopia and astigmatism. This may cause eye strain if not corrected.

You can consider getting a pair of lenses that have UV coatings, anti reflection coatings and perhaps a slight color tint for glare from the screen.

just get a normal AR lens for computer. that will help alot already. relax the muscles.

6/6 i can see 100% accuracy
6/5 i can see 100% accuracy
6/4 i can see 60% accuracy
6/3 i can see 30% accuracy
6/2 cant see anymore, if there is such a thing as 6/2.
yap, been to 3 shops. all 3 said the same thing of my eyes.

also my eyes are more developed for night. which may be the reason why i do better in the tests. 2 specialists confirm that for me(the lasik surgents)

my room is usually dark, black out curtains are usually drawn.
my room lights uses philips graphica, and so is my diy table lamp.

Cool. Haven't really seen one for myself. To be accurate none. Usually patients with that high prescription power would not be able to achieve VAs of better than 6/6.

What do you mean by "do better in the tests"? It can be true that people have good night vision but do you mean you read the chart better in a dark room as compared to a lighted room?

 

[purezerg]

yap. isnt the test usually conducted in a darkroom with the board backlit?

someone told me before, cant remember who that usually human eyes are 60% receptors for day, and 40% for night. but in my case it's the other way around where night is better for me. so my receptors are 40% day/60 night. but only 1 person told me that. so not sure how true that it. but i'm open to retesting my eyes again.

'but i wonder why u need good corner to corner optics when our focus is very much lesser than the lens height and width itself.'

i shoot with both SLR and hassleblad. with a viewfinder, i cant turn my head,i can only shift my eyeballs. so that is why i need maximium possible corner to corner.


as for essilor, i remember now, field of sharpness is around 50 degrees, but chromatic abberation starts at nearly 40 degrees.
essilor glass 1.8 index. not sure which generation, year 2006.

basically my degree hasnt change since 2004, but my va seems to slowly get better has i specialize deeper into photography.

By right the test should be conducted in a brightly lighted room. Most who do it in a dark room are lazy to do it in a bright room because of reduced contrast. Most people who do it are just in for sales IMHO. Faster eye checks =more time for sales.

It is not true that photorecptors ar active at night. There is no such theory. Photoreceptors are bleached or activated once exposed to light photons. All of the rod recepptors(for vision in dark environment) will be bleached in the day. In the day cone receptors are also bleached but they send signals for motion,speed,colour,etc. In the night there would be insufficient light to bleach cone thus, no colour vision at night.

Your view in the viewfinder wouldn't be affected. At most you will be looking through the center and few degrees off center. So there is no need to get such lenses u mentioned. In fact we were not taught of such corner to corner nonsense. What you are stating might apply to photography but not prescription lenses. If you really want to factor in the field of view, what I can tell you is, once you are off center, not only there will be chromatic aberration. There will be all kind of aberrations induced; astigmatism,spherical aberration,coma,trefoil,tetrafoil,secondary astig,etc.

So don't worry so much. For myself. I use nikon lenses because they are "sharp and define" for me. If u are worry of scratches, chromatic aberrations, get contact lenses. Contact lenses do not induce prism effects thus no chromatic aberration in that sense.

Try getting custom soft lenses. Those conventional lenses. Most disposable lenses in the market are made to fit the general population and mostly the caucasian population. Thus, it may not have the perfect power for you. I mean the step increment of every len may not be available. Let's say ur rx is -9.25 and the only closest available is -9.

Another option would be to get GP lenses aka hard lenses. They provide the best optics in the world of Prescriptive lenses.

 

[xiao_cai7]

Anybody know how much roughly does a Prada spec(not sunglasses) cost? the frame cost how much?

More than $238, cause that was the RRP for my Evisuand is defintely Prada more expensive than Evisu.

However the shop owner very nice uncle gave me good price.If you interested to check out, i can PM the shop address.

hard lenses? hmm. thats something i can consider. I had the impression that all contact lenses are equally bad optically. i'll give hard lenses a try on my next trip back to singapore. kumsia.

$450 odd...i got my prada plastic frame about 2 years ago, about that price not including lens. . .

Have you tried hoya bi aspheric lenses? or zeiss glass lenses? maybe you can let us know your experience with these.

If scratches is an issue, glass is the only way to go. As for the chromatic abberation, you can consider lenses that is of a lower index which have a higher abbe value. very high index lenses usually have higher chromatic abberation. I assume you are using 1.74 index lenses. So you can go for bi aspheric 1.67 index instead. or 1.71 (from hoya).

Otherwise you can always go for soft contact lenses when you do your photography. With your prescription there should not be any issue.

AS for lasik, your prescription is also quite ideal. but since you need to have very high contrast and wide field of vision and and very sharp vision, I don't think any eye speciallist will take on your case lest you complain after the surgery.

 

[warhunter]

read up on RGPs or GP lenses. only Soft lenses provide a poorer optical quality. GP lenses are still the best bet for you. get some one to fit them for you. A poor fitting GP lens not only feels "****ty" you don't see well either.

 

[narutiment]

getting a new pair of spectacles soon, need some recommendation on lens and frame. And also the shops that offer them.

Prefer:
- light weight (my current pair is pretty heavy, which strains my eyes after prolong period of wearing)

Is the Puma : No Limit good?

Budget : About $200

 

[remy06]

anyone bought eyewear from these online stores before?any reviews?

Whatever it is depends on yourself. You already know you're on the $200 budget. work towards that. all you have to know is you look good, feel good and pay what you think is worth.

I don't get it why people are asking, "Is gucci, prada, puma, adidas, everlast, etc. (any brands whos main business isn't in eyewear)" THEY ARE ALL THE SAME. Since it's not their main business to make eyewear, they get licensed manufacturers to produce them.

the same damned factory in LETS SAY CHINA, may produce sh(i)t loads of different frame.

That's why, get what you look good and feel good in. No point getting a prada, gucci, chanel to only know that it's made in let say again CHINA?
