Take care of your eyelgasses

It is released by authority that tens of youngsters become blind due to unscientific usage of contact bifocals lens every year in the United States. Aiming at this severe phenomenon, we provide seven methods for prolonging life-span of contact lens.

1.      Remember to knead lens with hands.

The recent research proved that kneading lens with hands are much more effective than by any other machines or care solutions in getting rid of impurity and precipitates. It is suggested by some ophthalmologists bifocals that contact lens should be kneaded for at least thirty seconds every time.

2.      Replace contact lens every one or two years bifocals.

Even if you do not often wear contact lens, the material of the lens will age in one or two years’ time. At that moment, you must replace the old pair for a new one lest the old contact lens should do harm to your eyes.

3.      The lens cannot be dipped in physiological brine.

The physiological brine is totally without the function of sterilization. If you physiological brine to conserve contact lens, the bacteria will breed quickly and widely. As a result, your lens would be contaminated.

4.      Remember to use care solution of the same brand.

Care solutions of different brands may consist of different medical ingredients, so if you change the brand of the solution casually, your contact lenses are likely to be damaged.

5. Get rid of the protein precipitates at a fixed time every week.

There is no care solution in the market that can wholly get rid of the protein precipitates on the lens up until now. Therefore, we should use protein-dispelled fluid to get rid of the protein precipitates on the lens every week. It is suggested by experts that we should not dip contact lens in the fluid for more than twelve hours every time we do the protein-dispelled work.

6. Pay attention to the expiry date of the care solution.

Before unsealing the bottle of contact lens solution, take a look at the expiry date. Once it is out of its time limit, throw it right away, for the solution would probably have gone bad.

7. Be careful of ill-using rewetting drops.

Lots of people wearing contact lens abuse rewetting drops nowadays. Every time they feel something uncomfortable in their eyes, they tend to drop some rewetting drops into eyes. They misunderstand that the rewetting drops are of magical power which could deal with all the problems in eyes and keep eyes healthy. Actually, ill-using rewetting drops would do great harm to the cornea.

Take contact lens wearers who have to face computer screen for a long time in their works as an example. Generally speaking, their eyes would tend to become dry or get tired at certain intervals. At that moment, most of them turn to rewetting drops of antibiotics. In fact, it is a damn wrong way of comforting eyes, because long-time immoderate watching is inclined to be the radical cause of the ill symptoms mentioned above bifocals. The rewetting drops are used for killing bacteria and virus but cannot tackle the problem of long-time immoderate watching.

In addition, due to the antiseptic in most of the rewetting drops, the conjunctiva cells can be damaged if you ill-use it for a long time. If you have some eye diseases such as exophthalmia or blear eye that need eye drops, remember to use it under the guidance of oculists.

In addition to the right choice for contact lens, the maintenance for contact lens is also quite important. It not only can prolong the time of use, also can make contact lens healthier and safer. There are some notes for it. 

First, maintenance for contact lens can be in accordance with the instruction of maintenance lotion. Generally, the focus of each bottle of maintenance lotion is not the same, and these lotions do not have the so-called quality difference. Actually, as long as followed the instruction of the use, all lotions can achieve the same cleaning effect. For example, bifocals contact lens should soak in hydrogen peroxide solution at least for 6 hours, while in other multi-functional maintenance lotion for 4 hours after scrubbing. Then, pay attention to the manufacture date and the storage life of maintenance lotion. Do not use expired lotion! Moreover, it is best not to continue to use the lotion which has opened for three month.

Second, periodically replace contact lenses. Even if the long-wear contact lens, such as rigid contact lens also need renew each one or two years. Besides, care about the use of disposable contact lens. Do not use daily disposable type as bi-weekly disposable type, or use bi-weekly type as monthly type, in order to extend the period of use. This behavior is quite harmful to the cornea. Moreover, do not soak the lens in the lotion for a long time. The lotion can gradually lose its sterilization strength, and then become a hotbed for breeding bacteria. Hence, those who not frequently wear contact lens can replace the soaking liquid every two days; while before wearing, be sure to sterilize and cleanse again.

Third, lens cannot be stored in physiological salt water, because the physiological salt water do not has the function of sterilization. Hence, if to put lens in such water, it is easy to promote the growth of bacteria, and then infect wear’s eyes.  

Four, the lens box need to clean up at least once a week, and replace every three months, avoiding becoming a hotbed for breeding bacteria. Generally, using cotton ball dipped cleaning liquid to clean the inside of the box, then putting the box under the hot water with 79 ℃ or more to disinfect, lastly dry it. Do not put lens box in the bathroom, for it easily gets mildewed in the moist room.   

Five, do not wear contact lens when  bifocals swimming because chlorine, bacteria, impurities, and other thighs will adhere to the contact lens, which can injure cornea or cause eye infection, even cause corneal ulcer. Hence, remember this point for your bifocals eye health.

Contact lenses are one kind of delicate and expensive product for eye health, so they are worthy of careful maintenance.
