Sure Vision Pinhole Glasses For Hypermetropia

We’ve all heard the term hypermetropia or farsightedness and some of us are more familiar with it than others. If you recall your physics lessons in school then you must have a complete idea of how hypermetropia works. But for those of us who can’t remember, why not go down the memory lane and refresh the lesson on hypermetropia.

The human eye is quite unaccommodating. This allows it to easily view focused images of both distant and nearby objects. The eye lens assumes a large curvature (short focal length) for bringing nearby objects into focus and a flatter shape (long focal length) for bringing distant objects into focus. Unfortunately, the eye cannot provide a wide variance in focal length which leads to many vision defects. Generally, the defect occurs at one end of the spectrum - either by not being able to assume a short focal length and focus on nearby objects or not being able to assume a long focal length and thus focus on distant objects.

Farsightedness/hyperopia/hypermetropia makes the eye unable to focus on nearby objects. The farsighted eye, on the other hand, has no difficulty in viewing distant objects. But viewing nearby objects requires a different lens shape - a shape that the farsighted eye cannot assume. Subsequently, the farsighted eye cannot focus on nearby objects.

This problem is mostly observed on those on latter stages in life, because of the weakening of the ciliary muscles and/or the decrease in flexibility of the lens. These two potential causes lead to the result that the eye lens no longer assumes the high curvature required for viewing nearby objects. The lens' power to refract light gets diminished and the nearby objects’ images are focused at a location behind the retina. On the surface of the retina, where the light-detecting nerve cells are located, the image is unfocused. These nerve cells thus detect a blurred image of nearby objects.

 

Correcting for Farsightedness

The cure for the farsighted eye is through assisting the lens in the refraction of light. Since the lens is unable to assume the convex and highly curved shape required for viewing nearby objects, it needs external help. Thus, the farsighted eye is assisted by using a converging lens. The traditional correction for hypermetropia is the same for kids and adults - a converging lens.

Since there are many annoyances and problems associated with the continued use of eyeglasses, Sure Vision Vision Correction Glasses has been created to treat hypermetropia and reduce your dependence on eyeglasses. The tiny holes in Sure Vision Pinhole Glasses For Hypermetropia change the light entering the eyes from an overpowering block of light to narrower and lower intensity light rays that effectively makes a more "organized" pattern for focussing.

The light coming through the pinholes motivates the ciliary muscles to become stronger, pulling the lens into the right shape. The theory is that the eye can be made to adapt to its environment and can be motivated to change shape towards normal. Improvements can be made within a few weeks in those who use reading glasses.
