Why I can see more clearly when I look through tiny hole? - index of/ tiny model jpg
I have about 4 in the eyes, but when I walk through a small hole in the thumb and index finger can clear to me without seeing the glass. How can this be?

Index Of/ Tiny Model Jpg Why I Can See More Clearly When I Look Through Tiny Hole?

When a lens bends light like a magnifying glass to the sunlight curve a small point, around a campfire .... some rays of light to break a lot, and onto the center of the lens, not to almost nothing. Used as seen through a small opening, light rays are not diverted or misused is minimal almost directly through the lens.
This is the basis of Pinholes in sports magazines that anyone can watch these glasses and go, without going through your doctor and get money for a test, then the frames and lenses and coatings. .... This is the type of display. You think you have a headache now? They work when it comes to nothing else but a squint will do the same.
For a more detailed explanation, let me know. Perhaps an optician (who is the master of refraction, refractive errors, how to correct these problems, contact lenses and other things ...), you want it explained.
Quite simply focus: lenses break light. Each beam of light through the center never bent by the lens
If your light deflection Sytem is inaccurate (ie, you need glasses), his vision blurred.
When you go through a needle "holes" you see the light, which are bent through the middle, passed by without the faulty system of the athlete. This explains the clearer picture!
b Paul has done an excellent job. the so-called "pinhole effect" and said his gut as an optical phenomenon that the "removal of paraxial rays or just the light rays observed directly from the source directly through the center of the cornea is known and projected directly to the center of the retina.
This can only work if literally any refractive error: nearsightedness, people with vision, people astigmatism and presbyopia. Works for everyone. everyone looks better by a small hole.
Therefore, it is not very practical for daily use is twofold:
1) most real situations require the use of a certain amount of peripheral vision, and seem to be disposed of in a pinhole camera
and / or
2) the majority of real situations in which the scanning eye movements, the constant movement of the pinhole camera
Paul B hit the nail on the head. Just so you know, were the cameras are used for many years, forcing people to spend hours immobile. Very little light passed through the hole, even if the picture is clear, and emulsions camera to a low level of exposure to respond quickly light.
This principle uses the same hole camera to see a solar eclipse. Your project an image on the inner surface of a box, a hole on the opposite side.
why are you a recipe box (myopia), because the cornea does not focus on one thing, in other words, if one thing that is fuzzy, but when your cornea, one thing is clear, immediate purpose, because instead of relying on a variety of things that you only have one.
