Low Vision Reading Lamp

Little about myself: 30yrs old, male, Caucasian. I have had the monocular diplopia to some degree for the past 2years or so.. give or take. It seems fairly stable, with any 'change' probably being merely my paying attention to it rather than a progression ( at least that is what I am going to believe for now :) ).

What I mean by this is what I described,.. Double vision in each eye , alone. -- If I cover one eye, I see 'vertical' double vision -- more adequately described as a ghost image.. as the ghost image doesn't 100% separate from the real/original source image. But it is your typical diplopia.

Very noticeable from LED's, lights, lamps, digital clocks,.. but also appears on non 'light sources'. It *is* more pronounced the darker it is (ie: the larger the pupil) -- but most aberrations are I would have to guess.. in general.

Not much to say about what I see here, except you could probably reproduce some form of this if you went outside at night and looked at a street light and squinted your eyes until the light started to blur and distort. The rays coming out are what I see with my eyes normally. Very obviously, and prominently ghost images.

Just to add to this, if it might be of relevance,.. is I see halo's around light sources, and starbursts on car headlights, computer power/hd leds (or any led) for that matter.

Thing that just a few years ago were very clear, and sharp.. are now a blur (light sources). IE: I used to love LED's for their look, brightness, clarity, low heat and so on .. now I cannot stand them because they (for I suspect by design) , really bring out this problem in my vision. They are piercingly bright now.. where even on the newer cars that have LED's as their primary source for things such as brake lights make me look in another direction as they are too bright (when they used to just look 'nice' a few years ago).

I am 30,.. as I mentioned, this started in my late 20's.. so it isn't exactly a huge 'age' factor.

Vision wise: -- I have had 2 Optometric exams , dilated fundus, etc.. and visual acuity is 20/16, with no significant astigmatism, or any other low order aberration found that needed correction. *They have found a slight degree of astigmatism, something like .25D - but being so minor I noticed no improvement with correction, so it isn't prescribed (nor does the correction take away the diplopia) (I did not specifically mention this at my last exam.. but will in the future).

One optometrist mentioned that I seem to have 'hawk eyes'.. hinting that my eyes 'over-do' something.. which gives me my acuity but makes convergence harder (IIRC).

At any rate,.. from all the research I have done monocular diploplia is extremely rare -- and nothing seems to really explain it in my case. I do think it is affecting my vision more than just the obvious ghosting I notice on light sources and to some degree on normal objects. As I am having a more difficult time reading, concentrating, focusing, and so on. I know visual problems often are the culprit for problems such as these and people don't realize how much so until they get the problem treated.

The only piece of possible explanation is that this is created by some HOA (High Order Aberration), which standard testing poorly, or does not, detect. I have contacted a local opthalmologist and have a standing appointment for a thorough exam for this.. and importantly the use of Wavefront technology to map my eyes for such HOA's. (This is by my request not theirs).

I just wanted to be very thorough with the question and line of thought so maybe you eye experts could give me your thoughts, or if you have anything to add, ideas,.. potential Dx's, etc.

Don't worry I don't take anything online as 'official'.. but I would appreciate educated (professional or well-read ) opinions on the matter.

Thank you,

You are describing HOA's. I would be suspicious of something in the cornea and that would be the part of the optical media that I would examine most thoroughly. If the cornea appears normal in slit lamp then I would definitely take a closer look with a topography. What you are describing is most often seen after refractive surgery (LASIK, LASEK, PRK) and as you very well describe get worse when the pupil is dilated and more of the refracted light from the cornea is allowed into the eye. HOA's after refractive surgery are a result of an irregular corneal surface or the result of the treated area being smaller than the pupil. If you haven't had refractive surgery before, then I would be interested in corneal dystrophy's that affect the surface of the cornea - Epithelial Basement Membrane Dystrophy, Reis-Buckler's, Salzman.

The lens is also not to be forgotten as slightly displaced lenses or misshaped lenses can cause monocular diplopia.

I am sure that your ophthalmologist will be able to shed light on the matter after your planned examination.

take care,

Professor Armstrong works at NASA, otherwise known as the National Aeronautics and Space Administration, where he is a well-known scientist there. We met with him and asked a number of questions about Quraanic verses dealing with the expertise in Astronomy. We asked him about iron and how it was formed. He explained how all the elements in the earth were formed. He stated that the scientists have come only recently to discover the relevant facts about that formation process. He said that the energy of the early solar system was not sufficient to produce elemental iron.

In calculating the energy required to form one atom of iron, it was found to be about four times as much as the energy of the entire solar system. In other words, the entire energy of the earth or the moon or the planet Mars or any other planet is not sufficient to form one new atom of iron, even the energy of the entire solar system is not sufficient for that. That is why Professor Armstrong said that the scientists believe that iron is an extraterrestrial that was sent to earth and not formed therein.

We read to him the Quraanic verse saying: «"And we sent down Iron, in which is Great might, as well as many benefits for mankind"» (Quraan 57-25).

Then we asked him about the sky and whether it had any gaps or rifts in it. He disproved this and replied that what we are talking about is a branch of Astronomy called the "Integrated Cosmos" which we scientists have only come to know recently. For example, if you have a body in outer space which travels a certain distance in any direction and then travel the same distance in a different direction, you will find that the mass weight is the same in all directions. Because this body has its own equilibrium, the pressures from all directions are the same. Without this equilibrium, the whole universe would collapse. I recalled Allah’s verse in the Quraan: «"Do they not look at the sky above them? How we have made it and adorned it, and there are no flaws in it?"» (Quraan 50:6).

Then we talked to Professor Armstrong about the attempts of scientists to reach the edge of the universe, and we asked him whether they were successful in this. He replied that they are fighting an uphill battle to the edge of the universe, we construct more powerful equipment to observe the universe only to discover that the new stars we see are still within our galaxy and that we have not yet reached the edge of the universe. He is aware of the Quraanic verse which says: «"And we adorned the lowest heaven with lamps and we made such (lamps) missiles to drive away Satans."» (Quraan 67:5).

Indeed, all these stars are adornments for the lowest heaven. He says that scientists have not reached the end of the universe. Professor Armstrong added that because of this, they are thinking of stationing more telescopes in outer space so that their observations will not be obstructed by dust and other atmospheric impediments. Vision telescopes using light are unable to travel long distances, so we replaced them with radio operated ones enabling us to see further, but we nevertheless are still within the boundaries. I mentioned to him this verse: «"So turn thy vision again: Do you see any flaw? Again turn your vision a second time: (your) vision will come back to you dull and discomfited, in a state worn out"» (Quraan 67:3-4).

Each time Professor Armstrong told us some scientific fact, we mentioned to him the relevant verse which he agreed with. Then we said to him: You have seen and discovered for your self the true nature of modern Astronomy by means of modern equipment, rockets, and space ships, developed by man. You have also seen how the same facts were mentioned by the Quraan 14 centuries ago, so what is your opinion about these?

He replied: That is a difficult question which I have been thinking about since our discussions here. I am impressed that how remarkably some of the ancient writings seem to correspond to modern and recent astronomy.

The book of God Quraan is a source of scientists.they will descover more facts in it..
