Sunglasses have a lot of functions and benefits. Wear sunglasses means more than looking fashionable. With the rapid development of society and civilization, people’s living standard has been greatly improved, and they begin to pay more and more attention to their health. As a result, I would like to introduce to you some knowledge about the sunglasses from a health perspective.

First, as we all know, UV rays in the sunlight are harmful to eyes. We should not expose our eyes to strong sunlight directly. The scientific research has revealed that UV light can damage our eyes’ retina and cornea. But don’t be panic. There is a simple and effective way to avoid this. That is to ware a pair of qualify sunglasses to protect your eyes from hazard UV radiation. At the same time, it can also reduce the risk of developing macular degeneration and cataracts. Sending a pair of sunglasses is not only sending wishes but also sending health.

Second, too much bright sun lights entering your eyes would cause the iris to close, which will make you to squint and thus feel uncomfortable. However, with a pair of sunglasses, you do not have such worries at all. A pair of sunglasses can keep the harmful UV light out of your eyes and help you see properly. So now you do not have to flatten your eyes even under the shinning light. It is time for you to open your eyes and show your charm.

The eyes are the windows to the world. How can we allow any to be done to our delicate eyes? We should try our best to give any protection we can think of to them. Do not just care about your skin and your hair style; you have given them enough attention. It is time to turn your concern to your eyes. Buy yourself and your friends a pair of sunglasses, you will bring them not only surprise, but also fashion and health. I strongly recommend that sunglasses sent as a gift should be considered.

When we mention the protection of eye vision, most of us will first of all think up the health care of eyes. However, according what experts say, apart from eye health care, the well balanced diet is an influential factor.

Too sweet food may harm the eyes. As we all know, children are mostly fond of desserts. But beyond our thought, if we have sweet food in a long run, the eyes may get bad influence. It is showed by modern medicine science, people who have excessive amount of desserts for a long period are easy to suffer from eye diseases, among which myopia is the most common one. Generally speaking, the body needs a large quantity of vitamin B1 to consume sugar content. If we take in too much sugar, vitamin B1 will be out of supply. In addition to that, extra sugar content will also reduce the calcium. All in all, these may cause and worsen myopia.

Furthermore, if we eat too finery food, our diet will lack in chromium; and if we eat too much soft food, the facial muscles could not get enough exercises. These may result in eye problems some day.

Different eye diseases could get better by eating. For not only myopia but also other eye diseases caused by diabetes, it is important to control blood sugar through diet. Experts have offered some tips to various eye diseases by matching healthy food to get better cure.

Myopia: Hard food and coarse food grain (e.g. maize.sorghum.millet.etc. as distinct from wheat and rice) are good for myopia, so we should have more often. We also need to eat fishes, grains, citrus fruit, and red fruit often, which have great effect to the prevention from worsening the eye vision. At the same time, we should eat less sweet food in order to avoid the deepening of myopia.

Dry eyes: Owing to working at the desk or watching the computer screen for too long time, we use our eyes too much. Some of us may feel the eyes are very dry. If so, we need to have more different kinds of fruit, especially the citrus fruit, and we should form a habit of being fond of eating green vegetable, fish and eggs.

Farsightedness: It is suitable to have a bit more garlic, onion, milky product (low-fat milk), dry fruit, animal’s liver, and fine rice. We should eat less food with high fat.

Glaucoma: If we suffer from this eye disease, the eye pressure may be very high, so we should have less greasy food. If possible, drink less tea, coffee and wine, and try to give up smoking.

For example, some contact lenses are also available to presbyopia persons in the market, but the eye experts have pointed out that the use of presbyopic contact lenses must meet certain conditions. For instance, he or she is shortsighted, and has been used to wearing contact lenses, thus it is certainly easy to wear presbyopic contact lenses. But presbyopic contact glasses probably could not deal with astigmatism, so they are not suitable for myopic people with deep degree of astigmatism.

As to those who never have myopia and want to wear presbyopic contact glasses, they might need some time to learn and adjust. Maybe some people can not wear it because of adaptation or their own problems like dry eye, finally they still choose other ways. In addition, this kind of contact lenses only help patients to see objects in a close distance, not are accepted by everyone .

Eye expert says that if you change shortsighted contact lens to presbyopic contact lens you will find your ability of seeing long-range view is not good than before. But the general white-collar workers wear short-sighted insead of long-sighted glasses, because their work mainly is to look through documents by computers. As long as they can see clearly the short-term things ,it doesn’t matter a lot when they see the long-term worse.

The most common way to rectify presbyopica is to wear the glasses with right degrees, including two kinds below, which normally are used for nearsighted people. Bifocal glasses: two focus; wearers should use different areas of lens to see near or far. For example, look far with upper focus, such as watching television; lood near with lower focus, such as reading. The double-focus eyeglasses bring convenience to a certain extent, but meanwhile they are different from general shortsighted glasses. As a result, it requires process to adapt this kind of glass.

progressive spectacles: which has multiple focuses and the degree varies from up to down, ususlly the up for far view, the down for close objects and the midst for middle-distance things. The convenience of gradual glasses is favored by many people. Not only the middle aged and elderly people, even some parents let their little children to choose gradual glasses.

Furthermore, presbyopia sufferers without myopia can wear reading glasses only for near vision. This kind of glasses is only to pick up when reading, and take off on the other time. People who wear contact lens duo to nearsightedness can wear presbyopic glasses at the same time according to the instructions of oculists.

However, some people wear contact lenses for a too long time that they even do not take them off when they go to sleep. In fact, contact lenses are not supposed to wear for more than eight hours. There are some long-term contact lenses in markets advertising that they can be worn for a week without taking off, which is fake propaganda and does great harm to your eyes. It is best not to wear contact lenses over night, during the day you can wear, but you had better remove contact lenses over night. However long a pair of contact lenses can last, they cannot be totally not airtight.

Long time oxygen-poor for cornea gives mold the chance to nourish and cause infection. Moreover, contact lenses of the previous night can gather dirty matters like dust if not cleared in time and may cause conjunctiva infection as a result. Many people have the habit of siesta. It will be best for you to take off contact lenses and put them in the matching tending liquid. You may wear them after you wake up and wash your face. Thus you can relax both in body and eyes, and create chances to make your eyes breathe freely. It’s important for you to wash your face after you wake up, it can clean out impurity and dust in your eyes and it’s more beneficial to the sanitation and protection of your eyes.

There are still some people who do not remove contact lenses when taking the bath. If shampoo or shower gel gets into eyes, they will contaminate contact lenses and cause discomfort in the eyes. What`s more, some fall contact lenses in the bathtub. So I strongly suggest that you should get contact lenses away from eyes when having baths.

In addition, it`s right for people starting using contact lenses to wear less 4-5 hours a day. Once your eyes feel sore and exhausted, you should take it off at once. Gradually you will adapt to wearing it.

We recently compared buying lenses online vs. the high street, and although buying contact lenses from the high street will also get you free check-ups and the lenses delivered to your doorstep, it can also leave you out of pocket.

Alison Hunt also checked out daysoft lenses, which offers contact lenses from as little as £9.98 for a month’s supply.

Daysoft is a one-size-fits-all lens, and claims its ‘Uni-Fit’ design allows it to replace lenses which have a base curve (BC) of between 8.3 and 9.2 mm and a diameter between 13.8 and 14.5mm. Its lenses also have two different liquid contents – 58% or 72%.

So, in theory, if you wore 1 Day Acuvues, which have a BC of 8.5mm or 9mm and a diameter of 14.2mm, or Focus Dailies, which have a BC of 8.6mm and a diameter of 13.8mm, you could wear daysoft lenses.

But with such large differences between 1 day Acuvues and Focus Dailies, I don’t see how the same box of lenses could be right for both lens wearers. After all, choose the wrong lens and it will feel like you have grit in your eye – or worse, it could do more lasting damage.

Our guinea pigs at lovemoney.com also had mixed reactions to the lenses, and most felt they would not switch brands just because of the price.

If you are brave enough to try Daysoft, they do offer a full money back guarantee, provided you’ve used no more than seven pairs when you return them.

Hard lenses are produced from hard gas-permeable plastic and it covers only part of the cornea. Today colored lenses are also available.

Contact lenses are better than eyeglasses for certain vision disorders like shortsightedness, long-sightedness, astigmatism and presbyopia. In the field of sports people prefer it because eyeglasses are hard to handle. Some prefer it for its wider view. Eyeglasses don’t cover the sides. Temperature, rain or perspiration does not affect contact lenses. And lastly people buy contact lenses for the feel and look good factor. It is a fact that eyeglasses do not look good on many peoples faces.

But contact lenses also have disadvantages such as:
1. The eye becomes drier than normal

2. Risks of eye allergy increase if the contact lenses are not handled properly.

3. It is not good for people with conditions such as diabetes.

Hence we can safely say that it is the condition that decides whether eyeglasses or contact lenses are better. It also depends on the user’s personal choice.
