If used correctly, contact lenses are a comfortable alternative to glasses. But people with dry eyes should be careful with these little visual aids, because wearing them can aggravate symptoms of dry eyes such as burning, itching and weeping. Here are a few tips for the correct use of contact lenses.
As convenient as small contact lenses may seem to you compared with uncomfortable glasses, contact lenses can be a stress on your eyes. You should therefore bear a few general things in mind when wearing contact lenses:
Once you get the hang of it, inserting your contact lenses can be quick. Newcomers to contact lenses usually need some practice. Proceed as follows:
1. Wash your hands thoroughly with soap and dry them well.
2. Remove the contact lens from its container and rinse it thoroughly with saline solution. Check the contact lens for possible damage.
3. Place the contact lens on the tip of your index finger. The contact lens must be placed like a hemisphere with the inside facing up. With soft contact lenses, the margins should slope slightly inward.
4. Keep your eyes open and pull the middle of the upper eyelid slightly upward with the middle or index finger of your other hand.
5. You can pull the lower eyelid down slightly with the middle finger of the hand holding the contact lens.
6. Look straight ahead and place the contact lens very gently on the surface of the eye. The contact lens “sucks” itself almost automatically onto the eye, i.e. you need not touch the cornea at all.
7. Slowly release the upper and lower eyelids. By blinking several times, the contact lens will slide into the correct position. By rolling your eyes from top to bottom and from left to right, you can adjust the contact lens, if you have the feeling it is not in the right position.
It is best not to apply makeup until after insertion, otherwise particles of mascara or eye shadow may get onto the contact lens and irritate your eye. The contact lenses should be taken out before removing your makeup.
Actually, you hardly feel modern, soft contact lenses. A foreign body sensation should no longer occur twenty seconds after lens insertion at the latest. If you still feel scratching, then a small foreign body may have got under the contact lens, or the contact lens may be the wrong way round on your eye. In this case remove the contact lens again and check that the margin is facing directly upward or is turned outward like a soup bowl.
Before replacing, rinse the contact lens again with saline solution to remove any little dust particles and impurities that could have caused the disturbing feeling. Also check whether the contact lens has any cracks or kinks. In that case it is damaged and should not be inserted back into the eye.
Before removing the contact lenses from your eyes, have the storing container and contact lens fluid ready so that you can immediately store the contact lenses safely.
There are different cleaning systems for the different types of contact lenses, whether rigid or soft, which are adapted to the respective lens type. Only daily disposable lenses do not require a cleaning solution, as they are disposed of directly after wearing. For all other contact lenses, be sure to clean them thoroughly and take care of them:
There are different solutions for cleaning, protein removal, disinfection and storage, depending on the different contact lens materials.
Through constant further development, contact lenses are nowadays usually well tolerated and rarely experienced as an unpleasant foreign body on the eye. When used properly, contact lenses are not harmful to healthy eyes.
However, if the contact lenses are worn for an excessive period of time, if they are not maintained in a perfectly hygienic way, or if an eye disease already exists, the contact lenses can become harmful to the eyes and additionally aggravate existing symptoms, for example in the case of dry eyes or conjunctivitis. Then you should remove the contact lenses immediately and put on your glasses instead. The same applies if you have a febrile infection or a severe cold. If necessary, you should then replace your contact lenses with new ones.
Damaged contact lenses should not be used under any circumstances to avoid possible damage to the surface of the eye. Dispose of this contact lens and use a new one.
