Types of reading glasses for presbyopia
Vision decline is inevitable for most people due to natural aging. When people reach 40 years old, the most common vision problem is presbyopia, which makes individuals unable to see objects that are close on hand. Presbyopia is not a serious vision defect, but it can be quite bothersome. Materials reading can be affected.
Presbyopic individuals always have normal levels of distance vision so that distant objects are still clear. But daily activities such as writing, reading, sewing and long hours of computer work can be very difficult and even cause severe headache. Presbyopia is such a natural phenomenon that only the nature can be blamed.
There are no preventive solutions to presbyopia. The only way is to treat it. Reading glasses are the most popular solution to presbyopia. In general, there are full frame reading glasses and half frame ones. Full frames are suitable for people focusing on close work regularly. The limitation of full frames is that they are effective only for long hours of close reading. If someone tries to see distance objects, the vision is blurry.
Half frame reading glasses are developed to solve this problem. This type of reading glasses sits low on the nose. Wearers can peer over the top part of the glasses in order to see distance objects because this part has no reading prescription.
Reading glasses may be annoying if one person has to pull them out at public places. Some wearers feel embarrassed to get out their reading glasses in public when they need to read some materials. In this case, folding reading glasses can be very helpful. This type of reading glasses can be slipped into cases that look quite like pen holders. Folding reading glasses in cases can be easily carried in the pocket. What’s more, these glasses are always equipped with hard frames so that they will never be broken or twisted easily.

A variety of means to ease computer eye strain
About 50% to 90% of computer workers are being affected by bothersome CVS symptoms such as eye strain. Researches have revealed that this discomfort can cause physical fatigue, decreased productivity and increased work mistakes. The following is a detailed introduction on how to address CVS.
The National Institute of Occupational Safety and Health (NIOSH) recommends people to take a computer eye exam before computer work, and tell the doctor your computer work frequency. Excessive light from either exterior sunshine or interior lighting brings eye strain at a higher possibility. The proper lighting should be about half of that in most offices, so that you should close drapes, shades or blinds to reduce outside light and use lower intensity bulbs and tubes.
Light glare and reflections from walls and the computer screen also contribute to eye strain. Many convenient ways are available to solve this problem, such as setting up an anti-glare screen on your monitor, painting bright walls into dark and applying anti-reflective coating to your lenses.
Liquid crystal display (LCD) is built with an anti-glare surface, which is beyond a cathode ray tube monitor (CRT). Even set to the highest possible refresh rate, CRT screens may cause image flicker and lead to eye strain. For LCD, a higher refresh rate and larger size are more helpful.
Most displays provide a series of settings for adjustments. The screen brightness should be the same as the ambient environment, and the contrast between the screen background and the on-screen words should be high. Text size and color can also be adjusted.
Most people blink less frequently during attentive computer work, which may lead to high rate of dry eye. Long period of non-blinking phase speeds the evaporation of tears so that your eyes can not get rewetted in time. Dry environments can also bring dry eye problems. You can ask your doctor for artificial tears to ease this problem. Lubricating drops are not capable of reducing dryness and irritation.
Two ways of exercising your eyes to reduce focusing fatigue are widely applied. One way is gazing at a distance object outside every 20 minutes, which relieves the eye’s focusing muscles. The other way is to alternately look at a distance object and a close thing. Frequent blinking is also needed during these exercises.
The NIOSH advocates that more frequent small breaks during the work day can sharply reduce eye strain and discomfort. It is also recommended to divide long breaks into several short breaks. During the break, you can stretch your arms, legs, back, neck, shoulders or do other quick sequence of exercises.
Many factors that involve your computer workstation may also affect your comfort. Your desk lamp should not shine into your eyes or onto the computer screen. You should properly place your chair at proper height to get a suitable posture. Ergonomic furniture can also provide useful help.
A variety of computer glasses including single vision type, bifocals and trifocals offer the greatest comfort for computer use.

Of which, bifocal reading glasses are very typical and useful. However, as for those sportsmen, who also have such eye problems, they may do not know what to do. The reason is very simple, they can not see objects clearly if do not wear bifocal glasses; or their eyes can not be protected if not with safety glasses. No one wants to carry bifocal glasses and safety glasses at the same time, for doing so are neither inconvenient nor impractical. Fortunately, every problem has its solution- there are bifocal safety glasses in the market. Bifocal safety glasses, as their names show, are functionally the combination of bifocal glasses and safety glasses. Even though, those glasses are almost the same as other ordinary glasses in weight, styles, etc. Up to now, more and more sportsmen or non-sportsmen who are in need of bifocal glasses begin to use bifocal safety glasses. Maybe some people are now just hesitating whether to buy them, here are two basic facts about those glasses.

With those glasses, people can see clearly of anything outdoors on the one hand, and have their eyes safely protected on the other hand. This was unimaginable for them before. During then period, they could see clear of neither nearby nor afar objects. This was very horrible for any one, let alone for outdoor sportsmen. Or in some other serious cases, when some of them could not stand the pain of staying indoors everyday, they decided to go outside with bifocal glasses only, and the results were-their eyes were seriously damaged.
Second, bifocal safety glasses are also representatives of fashion. This is because bifocal safety glasses are now different from traditional safety goggles. Generally, safety glasses are made in the form of goggles. And wearers have to tighten them around their heads. Doing so is really brothering and uncomfortable. Fortunately, some innovations are made in bifocal safety glasses, for they are almost the same as other glasses, not goggles. The first impression of those with bifocal safety glasses can give is coolness. Or in some other cases, the design of bifocal safety glasses always keeps up with the latest fashion in the industry. In particular, some tinted bifocal safety glasses with special styles have attracted a lot of people. For example, some young women are arduous for those glasses in purple.

Benjamin Franklin and Bifocal Spectacles
Bifocal eyeglasses, also called bifocal spectacles, are some of the most widely used glasses among people who have presbyopia and other nearsighted vision problems at the same time. However, many people still do not know who has invented bifocal spectacles. And even for those who know something, they are still uncertain about the answer. Benjamin Franklin is only legally and universally recognized inventor, though many data has it that other people may be the first creators of bifocal spectacles.
It matter little what the reality is, but the story about Franklin and Benjamin Franklin is really very interesting. Here is the bifocal glasses history.
Compared to other glasses, bifocal spectacles are much younger with a very short history, less than two and a half century up to now. They do not come into being till 1784 when Benjamin Franklin spends more time in reading. As one of the most respectable state men in the history of US, Benjamin Franklin has also made many achievements in other fields. Of which, Bifocal spectacles are very typical. During that time, he becomes older and gradually looses his vision, just because of presbypia and other eye problems probably. He has to replace the glasses for farsighted vision when he wants to look afar; and he has also to replace glasses for nearby vision when he reads. This is very boring and inconvenient. Therefore, he wants to change such situation- whether the two lenses, one most convex lens and another least convex lens, can be placed into the same frame. As one of the most creative men in the world, Franklin has found the best way and embedded the two lenses in the same frame successfully. With the new glasses, he thinks now that there are two different focuses on each lens, they should be called bifocal spectacles.
However, the first bifocal eyeglasses invented by Benjamin Franklin are totally different from what people can now see. Generally, for each pair of glasses, there are four lenses. That’s to say, he has used two wholesome lenses on each side of the frame for one eye. Therefore, it can easily explain why the early bifocal spectacles are very heavy to wear and funny to see. And such situation dose not change until the 20th century when more people have to wear glasses and great achievements are scored in the industry. Those modern bifocal eyeglasses are combined by two half-cut lenses. And now, more and more innovations are made in bifocal glasses. This is what Benjamin Franklin has never thought of.
