Is It True That Only Aging People Require Bifocal glasses?

Bifocal glasses refer to those having one section that corrects for distant vision and another section that corrects for near vision and Benjamin Franklin is believed to be the one who invents bifocals.

The reason why it is called bifocal derives from its special designation of the two lenses of different convexes posited in respectively the lower and upper half of the frame. At the very beginning the two parts were just combined directly, resulting in a sharp switch for the wearing when s/he read something from the above or from the top. Later, to solve this problem, at the end of the 19th century, Louis de Wecker developed a method for fusing the sections of the lenses together.

Bifocals were originally invented for the elders to read, and then people think that only aging people require bifocals their development of presbyopia all the time, but this is a misconception. The fact is that bifocals are also suitable for those who develop a combination of nearsightedness and farsightedness. For them, the lenses posited in the lower half of the frame are for nearsightedness correction while the upper are for farsightedness correction. Therefore, when you find young friends around you wear bifocals, do not feel surprised.

Based on the same principle, bifocals can help correct any combination of two different eyesight conditions, for example, bifocals can help correct astigmatism that is present in combination with other refractive defects.

However, every coin has two sides, bifocals lead to discomfort for the sharp vision switch from the upper to the lower or in reverse as mentioned above. Some wearers may experience from headaches and even dizziness. For the computer users, they would probably experience muscle fatigue due to the unusual angle and constant movement of the head.

Fortunately, with the progress of relative researches on it, new models come into being, the trifocal glasses and progressive glasses. As their names self-explanatory, the former consist of three corrective lenses on each side of a pair of glasses, for a total of six lenses for a pair while the latter are characterized by a gradient of increasing lens power. Both of them work similarly to bifocals do, but they aim at reducing the sharpness between different corrective lenses so as to make wearers suffer from fewer headaches from strained eyes.

Those progresses are not enough, researchers are trying to make new materials to make better bifocals, and to discovery new technologies that may provide a method which can selectively adjust the optical power of a lens.

At last, I would like to remind you that if you find yourself a need to wear bifocal glasses, you can firstly consult with an optician, who is best to be licensed, for there are different types of bifocals. With her/his help, you can decide which type of is the one for you.

How to Treat Glaucoma

Glaucoma is a disease that affects the eyes and if not treated can permanently damage the optical nerve which can result in blindness and loss of vision. This article will detail a few Glaucoma therapy treatments available and the advantages and disadvantages regarding each.

The damage caused by glaucoma is commonly caused by a high intra-ocular pressure. This pressure is provided by a clear liquid, aqueous humor, which flows through the eye helps to maintain and nourish the tissue within the eye.

In circumstances where the production of this liquid is increased and the methods for drainage are decreased damage occurs to the nerves and peripheral sight is lost, this effect is called Open Angle Glaucoma (OAG).

A way to treat this form OAG is to assist in lowering the pressure within the eye, the treatment for this is usually through eye drops, laser therapy or surgery.

The most common Glaucoma therapy treatments are the eye drops, the disadvantages for using eye drops are that they can be expensive, messy and can have side effects. In addition to this depending on the severity of the OAG you may need to use them for the remainder of your life. Some of these drops assist in draining the fluid whilst others act to reduce the amount of fluid produced, the effect being the same.

Lasers also can be used for Glaucoma therapy. This technique is called laser therapy. Laser therapy uses lasers to target the cells in the eye which contain melanin which is a natural pigment. The body will then act to repair the damaged cells and as an effect of this will decrease the pressure that has built up within the eye.

Glaucoma as stated can cause permanent loss of vision if it is not treated. There is no way to determine whether the glaucoma has been successfully controlled and as such if you have this condition you should make regular trips to your GP to ensure it does not get out of control.
