Do Not Stare at the Computer for a Long Time While Wearing Contact Lenses

April 7th, 2011

With contact lenses we can do sports freely and see things clearly, but we should not stare at the computer for a long time. Most of the contact lenses wearers will feel dry in the eyes or have other uncomfortable feelings after facing the computer screen for a long time. This is because they don’t blink eyes frequently. Currently, the commonly used contact lenses are made from high polymer material, so their oxygen permeability is not so good, which prevents the eyes from breathing oxygen to some extent and thus causes the cornea anoxygenous. Besides, the long time staring at computer makes the eyes under high pressure. The normal people blink more than 20 times every minute; while people who wear contact lenses sitting in front of computer blink only 4 to 5 times per minute.

What’s worse, almost all contact lenses will gradually decompose and degenerate under the radiation from the computer. Some of these decomposed micromolecule will reach the crystalline lens through lymph circulation and then combine with the repaired tissue of the crystalline lens, so that to form new polymer. A small amount of polymer will be discharged from the inner part of eyeball to its surface and finally be discharged in the form of gum. However, when the polymer is too much the dust and debris in the eyes will accumulate in the crystalline lens, thus gradually develops into cataract.

Therefore, for myopic people who have to face the computer for a long period everyday, they had better wear framed glasses. If they must wear contact lenses, they should pay attention to the rest of their eyes. For instance, look into the distance after one hour staring at the computer; not rub the eyes but wet them by using the eye drops that don’t contain preservatives when they feel dry in their eyes; take off the contact lenses to leave sufficient time for their eyes to discharge wastes during having rest; and wash hands before taking off their contact lenses when they are going to bed. Moreover, do replace the contact lenses once their service life is exceeded.

What Should Contact Lenses Wearers Notice While Camping

March 29th, 2011

Many myopic fans of outdoor activities would love to wear contact lenses in the open air, but do you know contact lenses have two enemies, namely cold and dirty. But here are some tips to cope with them.

As we usually contact some dirty things outdoors, if there are dirt or other such small particles between the contact lens and the eyeball our eyes will be painful while they are rolling because of friction which will even lead to permanent eye diseases. Therefore, please make sure your finger is clean when you indeed have to touch your eyeball or take off the contact lenses. If it is impossible to wash your hands with soap, you should at least rinse your fingers that are about to contact your eyes with the water you take with. If there is no water, it is better to wash your finger with the contact lens solution than to contact your eyes directly.

In order to avoid the contact lenses from losing during taking on and off while you are camping, the best solution is to take on and off your contact lenses with your elbow supporting on the damproof pad or sleeping bag. In this way you can easily find your contact lenses even if they fall down the damproof pad or sleep bag by accident. What’s more, they will be much cleaner than falling down on the ground.

Do remember to take a bottle of solution with you while preparing your travel bag before setting out. If you forget to bring it carelessly, you can put the boiled water into a clean vessel, and then use it instead of contact lens solution after it is cooled.

If you intend to stay outdoors for a long time you must take a pair of framed glasses with you, otherwise you will get troubled once your contact lenses are lost. Additionally, OSA points out that long-time wearing of contact lenses is harmful to the eye health, so it is better to wear framed glasses while camping.

Get an exam for cornea before you wear contact lenses

November 14th, 2009

Nowadays, through the technology of contact lenses has got an incredible improvement in test and diagnostic capabilities, still, contact lenses can damage contact lens wearers’ eyes in a complicate way.

Besides the basic testing measures such as refraction, cornea readings and corneal health evaluation, proper contact lens fitting and follow ups still need to take the corneal topography and endothelial cell count measurements into consideration. The corneal topography examines include the tests of the outer most layer to make sure whether the cornea irregularities, curves or pathology. The endothelial cell count examine the inner most layer, which is one cell layer. The number of cells per unit area and the quality of the cells are evaluated by the ECC, it said there are 2400 cells per unit area which are similar in color, shape and regimented. Once any change happened in the cell, the cell would die and leave a gap in its original position. The function of the endothelium is pump water out of the cornea. Once it gets some hurt, it will affect the corneal swelling, thickness, glare, and, of course, the ability of vision adjusting will decrease.

People who wear contact lenses should get an ECC to certain the function of the eyes is okay. Once find any abnormal situation, the wearers should make some changes in contact lens wearing.

The size and appearance of the cell in endothelial layer cause polymegathism, which means the ability of the endothelial cell to pump water from the cornea becomes weak. As a result, people get opacificrion, which also called cloudy cornea. Essentially, the changes are caused by the increase of lactate, the PH has changes, which decrease the cellular ATP and increase the endothelial hypoxia.

All of these are caused by contact lenses over wearing. The contact lenses not so fit the eyes brings about the endothelium overload, which makes the number of irregular cells increase. Some cells may be really abnormal.

People who get serious Polumegathism contact lens wear should stop wearing contact lens or reduce the time of wearing contact lens a lot, less than 10 hours per day. There exist highly permeable contact lenses which can allow enough oxygen to cornea.

People should do their best to avoid any corneal surgery which may cause endothelial cells loss. What is more, future cataract surgery may develop the technique to avoid losing of endothelial cells during the surgery.

In general, people who want to wear contact lenses should get an exam to make sure their cornea are totally healthy and do not put their frail eyes at risk.

Basic knowledge of contact lenses

October 25th, 2009

Contact lenses have been around for over one hundred years. In those early days, some people were not suitable to wear contact lense since the technologies were not so advanced. But nowadays, contact lenses are available for everyone. And contact lenses today are provided in more options that even colored ones are manufactured.

Contact lenses are one of the three ways that can correct eye diseases such as myopia, hyperopia and astigmatism. The other two are eyeglasses and eye surgery such as LASIK. Actually, contact lense has been the choice of a considerable population. In the United States, about 20 percent of people who need vision correction wear contact lenses.

To some content, contact lenses are special eyeglasses, because they also use lenses to help people improve their vision. However, the two types do have some differences. Eyeglasses are visible to others. They have obvious frames and lenses. In contrast, contact lense is invisible to others, because the lenses are made of transparent materials. This feature of contact lenses does help some people who prefer their appearance without a pair of eyeglasses. Contact lense also eliminates their need for eye surgeries.

Contact lenses can provide the vision correction effects as well as any eyeglasses. Once you put them on, contact lenses “contact” your pupils. Contact lense is large enough to cover your whole pupil even if you turn your eyes around in all directions, so that it can provide complete vision correction. Contact lense just provides unobstructed vision, which is helpful during sports and other activities.
