Take care of your eyelgasses

Summer is already on its way; walking on the street, many colorful sunglasses came into people’s view instantly. It seems as if with a pair of sunglasses, the whole atmosphere around the people begins to be much simpler and also makes people feel a sense of liberty. But most of those modern young people seem to be actually unaware of the real functions of the sunglasses, which are sometimes just looked on as a carrier of fashion.

Actually, although the sunglass can act as a facility to prevent the eyes from being harmed by the hot summer’s great sunlight, it is not really doing the effect of prohibiting everything harmful from entering the eyes. So it is very important to pay attention to those different sunglasses’ different functions, which are often mixed up.

Also, how to protect the sunglasses really can do some effects to the eyes, and it is generally like the protection of some common glasses for nearsightedness. The difference lies in that we take on and off the sunglass more often, if it is used carelessly, the lenses can be damaged easily, especially when there is dust or some other dirty things on the lenses, we should not use our hands to wipe them away, and otherwise, the lenses’ using length can be shortened by a single careless action.

Some people put the sunglasses in their pockets carelessly, on the head, or even hang on some objects; these can really do the effect of making the lenses become old easily or even causing the frame to break. The best way is to put the sunglass in its special designed box and then put the box in the bag so as not to mix the sunglass up with the keys or other small things and fret the lenses.

If you have a car, you may put the sunglasses carelessly before your own seat, this is actually improper. The summer’s sunlight may do some harm to your glasses’ frame, which is usually made of plastic. Besides all these, the lenses should always be put upward whenever we fold the glass.

So, with a pair of sunglass, I’m sure the new summer will be more splendid.

The ophthalmology and prescription of the progressive glasses is totally different from that of presbyopic glasses and bifocal glasses. It needs more scientific ophthalmological technology and stricter operating process. If any single chain of the whole process turns out to be wrong, it will not only result in money wasting but also be harmful to the health of consumers. Therefore, on one hand, the ophthalmologist should adhere to the professional morality. On the other hand, we, as consumers, need to have some basic knowledge on selecting progressive glasses.

Firstly, we need to know what we want and ask the ophthalmologist to examine our eyes to make sure whether there is a need for us to wear a pair of progressive glasses.

Secondly, if the examining result turns out to be that we have the need to wear progressive glasses, then the ophthalmologist will do optometry on our eyes—optometry both in near distance and far distance. Next, the ophthalmologist will use FCC as the elementary reading additional glasses for us, basing on our ages, errors of refraction, the present eyesight. 

Thirdly, choose and adjust the frame of the glasses. In the process of selecting a suitable pair of progressive glasses, the adjustment of the frame is very important. The following ten points should be carefully noticed:

1. The frame should enjoy a good stability. Generally speaking, you’d better not choose glass frame without brim, or the frame tend to warp.

2. The glass frame should enjoy enough vertical height, or the myopia part of the glasses is inclined to be cut away when the worker are doing severing work. Currently, the vertical height of the frame should not less than thirty-five millimeters.

3. The space below the glass circle and above the bridge of nose should be broad and deep enough to contain the progressive zone. It is better not to use Ray Ben frame which enjoys a space of highly slanting degree below the glass circle and above the bridge of nose.

4. The frame should be equipped with pseudostipules that have the performance of adjusting vertical height.

5. Under the precondition that the frame keeps no touching of the eyelashes, the smaller of the space between the frame and eyes is, the better the effect of wearing progressive glasses will be. After choosing the frame you like, try on it and then make some proper adjustment.

6. Make sure that the radian of the spherical surface in front of the frame tallies with the radian of your forehead.

7. Keep the frame balanced. Well tune the angle of the legs of the glasses so that the frame could be worn rightly on your face.

8. Oblique angle in front of the frame should be adjusted to 10~15 degrees lest that the frame should be in touch of face.

9. Adjust the pseudostipules so as to shorten the distance between the glasses and your eyes. The shorter the distance is, the better. But you should keep the glasses without the touch of your eyelashes.

10. The legs of the glasses should be well tuned until the frame is stably worn and you feel comfortable. 

At last, the ophthalmologist will measure the horizontal distance (pupillary distance) and the vertical height.

The first thing that comes to mind when one thinks of sun protection is to protect skin, hardly think of protecting eyes. In practice, researches indicate that eyes exposure to ultraviolet radiation will do injury and even cause diseases to eyes. Therefore, we should pay attention to eye protection from sunshine.
Please don’t look up into the sun. Delicate eyes are easily hurt.Short-time direct view to sun may result in transient giddiness. One may suffer from pain, tears, inflammation and blurred vision if he/she looks up to sun for a long time.
As is known to all, eyes are fragile and susceptible to ultraviolet radiation which would easily injury eyes. The UV ray of 280nm wavelength damages the cornea most badly and it brings about the conjunctivitis. The UV rays with the wavelength of 290-400nm are harmful to lens, which would result in cataract. Research suggests that one more hour you bask in the sun every day; you are likely to get cataract with 10% more chance. And now we should talk about some precautions.
When you are outgoing in summer, remember to wear broad-brimmed hat or use umbrella, a pair bifocal glasses is most effective in protecting your eyes. It is worth to note that the bifocal sunglasses you buy should be good enough in quality. Sunglasses of poor quality can’t help in protection but result in injury to eyes. One must buy himself/herself a pair of sunglasses with anti-UV function. Medical research shows that it is unnecessary to choose lenses with too dark color. Grey and light grey are more effective in blocking UV rays. People wearing contact lenses can buy UV-protective ones which are able to block 90% ultraviolet radiation. It would be safer to add a pair of progressive eyewear. Don’t work or do activities outside at noon because the sum at that time is strongest and prone to hurt skin as well as eyes.

Recent years, more and more middle aged people suffer from hyperopia. So the bifocals enjoy higher and higher market shares.But, by using bifocal or progressive glasses, one should pay special attention to the adjustment period.Let’s learn some tips in the process of adjustment together.
For green hand in using multifocal glasses, it is an important lesson to command the methods of seeing objects clearly in different distances.

• Distant objects: raise head; look at things with line of sight parallel to the ground through the upper part of lenses.
• Near objects: keep you head at an angle of about 45°with the horizontal surface; look down through the lower part of the lenses.
• See middle distance objects by looking through the middle area of the lenses.
• You can look objects from distant to near clearly by looking through the lenses from up to down.

For green hand in using progressive glasses, it is common to encounter with following uncomfortable feelings.

• It makes your head swim,be unsteady on one’s feet,have to be beware of the vision when exercising or walking upstairs.
• It is likely for you to be under the delusion that the space state is changing.
• You are unable to distinguish the objects on different distances.
• Your eyes may not feel well when focusing on the objects in near distance, for your eyeballs should move to the lower side.
• You may find objects you look via the peripheral part of the lenses are blurring.

So, it is best for people who wear bifocal or progressive glasses for the first time to move head instead of eyeballs when look at things.Try to look things in different distances through the corresponding vision area.

Prescription Sunglasses

You may sometimes find yourself driving down the road, sun shining in your eyes, as you search in vain for those clip-on that came with your prescription eyeglasses.

At times like these, you might find that prescription sunglasses are much more convenient and more than worth the additional investment.

Contact lens wearers, too, may find wearing prescription sunglasses is sometimes a far more practical alternative outdoors. For example, you may not want to wear your contact lenses on the beach where your eyes can become itchy and watery as you battle the effects of sand, sun, wind and water.
But with prescription sunglasses, you have the option of wearing them anytime outdoors without the need to search for clip-on sunglasses or deal with contact lenses.
