Yes
Is it me, or do they leave the eye looking less sharp? I know I have been in focus on the eyes (or at least one :D) doing some test shots and the eye ball is in focus, but the pupil is slightly hazy.

I will be conducting a test when I give my eyes a break from the lenses at the weekend, but thought I would seek advice from you lovely people :D:nuts:

Dave.
 
Do you have an astigmatism or a prescription where it's 1/4 or 3/4 of a unit? Contact lenses are only available in half unit incriments and even toric lenses, with astigmatism you'll never get it as good as a contact on an eye without astigmatism (or the same as glasses).

I hope that makes sense?
 
Makes sense, I do have a Toric lens in my right eye - Thanks, thought they looked a little 'cloudy' compared to some other shots I've taken of people :)
 
No worries, I have the same thing (and it's my right eye too). I prefer to either wear no lenses/glasses if I'm using the view finder or glasses when shooting using the LCD screen. Though it's not like you can just pop a lens out in the same way that you can take glasses off, every few minutes, LOL

I'm an optometrist.

The above is tosh.
 
The problem the OP may be having is the surface of the contact lens drying out.

If the lens is a hydrogel (soft) lens, the lens material itself is about 60-70% water on average and acts like a sponge so can go dry quite quickly. The surface of the lens may then reflect light more, or look uneven.

Try to blink just before the shot is taken, or keep a supply of artificial tears on hand.

When you say the pupil looks hazy, I presume you mean the iris (the coloured band). The pupil is just a hole: there's nothing to look hazy and nothing to focus on.

Could you post some shots so we can see what you mean?

Most contact lenses have a blue handling tint which may be more obvious on photography rather than the naked eye.
 
I wear contact lenses, my eyes are -22 on the dioptre scale:eek: blinking is a good tip before releasing shutter, dry eyes does make them appear cloudy, try blinking really slowly as well that helps, for a few blinks that is not constantly.
 
Wouldnt look hight for me though, couldnt see the ground.:D:D:shrug:

well that's what my opticians (4 of them) explained it to me over the past decade, they've all said the same as each other - that contacts could only be in half units and that for some astigmatisms contacts will never be as good as glasses, that it'd always be a bit blurry :shrug:

With regards to them drying out, there's some new ones on the market ATM, they're made of silicone and don't dry as fast
 
Soft contacts are renowned for not being on par with hard contacts or normal glasses. Even more so if there toric soft contacts. Not only are they not exactly shaped to your eye but they also deform. Depending on exactly what is required for your eyes you may be bale to try custom made hard lens.

Edit: just to add i did try hard ones and you could see great but i did not like them so dont use them any more. Now back to good old glasses

Ive made them over the last 7 years and will have to check into the Values available on the toric lens Not my Line and most if not all of it gets shipped abroad. I will have to check when i go back to work,the soft-lens daily disposables are in quarter values as well but not sure about Toric as its not my division.
 
Sorry guys, I have to bring some actual facts to this thread. I do not mean to criticise the well-meaning if a little misinformed posters.

Soft contacts are renowned for not being on par with hard contacts or normal glasses.

Not true.

Even more so if there toric soft contacts.

Toric softs occasionally don't fit correctly or are not stable enough on the eye, but this is rare. The majority of soft toric wearers are very happy.

Not only are they not exactly shaped to your eye but they also deform.

Soft lenses "drape" over the cornea - they do not need to be manufactured to exactly match the corneal curvature. In this way it could be said they match exactly the corneal curvature in wear.

Depending on exactly what is required for your eyes you may be bale to try custom made hard lens.

Every patient can choose to wear rigid gas permeable (RGP) lenses if they wish. Every RGP lens is custom made to fit the cornea exactly, there are no stock RGPs. The fact that most patients choose to wear soft lenses is a tribute to the comfort and quality of vision available with soft lenses.

Edit: just to add i did try hard ones and you could see great but i did not like them so dont use them any more. Now back to good old glasses

RGPs are uncomfortable until your eyes have adapted. In some cases the patient will not tolerate RGPs even after a long period of adaptation. Again, another reason why soft hydrogel lenses are the first choice for a new fit.

RGPs are good for unusual corneas, for instance irregular astigmatism. For the vast majority of cases, prospective contact lens wearers will have simple hyperopia, myopia or astigmatism, which can be easily and accurately corrected with soft lenses.

As I said before, the main source of dissatisfaction with soft lenses is dryness, which can be managed with blinking techniques, artificial tears, or changing the lens material. Mynx is correct, the new silicone hydrogel materials work well in preventing dryness.
 
Thanks for all the replies :)

I'll take some shots today or tomorrow without my lenses in.

In regards to my monthly lenses, and nothing to do with the original question, the toric lens is fine, I only struggle slightly with low light situations. These are soft lenses that you can keep in for the month :)

Thank you :thumbs: That makes sense with what they told me (cause apparently my right eye is wonkier than it should be, so makes sense as to why the last optician I saw said that some people can get a perfect fit but I never would in that eye)
 
Is it me or are people missing the point of the question? Isn't the OP referring to subjects wearing contacts lenses being slightly OOF...not the photographer's?!

That was the point :)
 
Interesting reading as i wear glasses and was thinking about getting lenses for when i am out with my camera. So some things to think about now.

exactly

i think you may be getting the effect of double glazing...twin planes...and a little bit of diffusion perhaps not evident normally

Honestly, I've found wearing contacts and taking pictures is harder than wearing glasses (I try to take my glasses off and shoot through the view finder and ajust the view on the view finder so it's not blurry, when I can). I was also told (and agree with) by a few opticians that my distance vision wouldn't be as good with contacts compaired to glasses. I've found that to be true with every daily and monthly disposables that I've tried.
 
I've been using extended wear contact lenses for about 10 years, no problem taking photos, in fact it's a pain when I'm using specs :)

this is all about the eyes in a portrait..?

I will be conducting a test ...............


when I give my eyes a break from the lenses at the weekend, but thought I would seek advice from you lovely people :D:nuts:
this seems to be dave's eyes causing the problem

Dave.

i really thought you meant the eyes of the sitter...etc and answered in such a manner
but i see you have trouble with your eyes in focussing due to your contact lenses
sorry

hope it clears up anyway dave...i wear glasses and HATE cameras with viewing only via a screen...even a big one
wearing glasses and photographing do not go together for me...and probably for others...that is why i guess there are dioptre corrections facilities on viewfinders
 
Sorry, to clarify it is the eyes of the sitter, in this case it was me (self portrait), I wear monthly lenses so took them out this weekend to give my eyes a break!

I too hate using the camera with my glasses on.

Think you were right in your first assumption of 'the double glazing effect'

I did take a couple of test shots, and my eyes look clearer in the photos when I'm not wearing my lenses

I was never confused :bonk: :D

Dave.
