Today, I just want to say something about contact lenses. First, I jus want to introduce what contact lenses are. They are functionally the same as eyeglasses that can be used for vision correction. However, they are totally different from glasses, for they can be directly put onto corneas. Of course, the cleaning of those lenses is also very easy, as some tinted indicators can assure they can be found easily.
Wearers should be very careful in selecting and wearing contact lenses, for those lenses will be directly worn onto corneas and this act may lead to some corneal problems.
Some people are not candidates for contact lenses. For example, for sufferers of allergies, diabetes, etc. contacts are not alternatives. Therefore, before wearing those lenses, people are suggested to do some eye examinations. Even though people are candidates for contact lenses, they should also follow some guidelines.
While purchasing those lenses, people should pay more attention to something, such as the quality and reputation of the vendors.
If the eye doctors are trustable, their advices are very important, including the products that they have recommended.
Of course, people can also choose to purchase contacts online. But there are many points to be noticed, such as the reputation of the online vendors and other consumers’ feedbacks.
Before inserting contact lenses, more attention should also be paid. People should make sure that their hands are clean, no dirty or bacteria should be left on. The reason is dirty hands will lead to eye infections.
While inserting those lenses, people should make sure that the contacts are well arced. Two hands should be used together-one to hold the eye lid and the other insert the contact.
Be gently while adjust the contacts to their proper position. Only after one has realized that those lenses are properly positioned can he open his eyes. Then make several blinks, so as to make those lenses much better adjusted.
Moisture is very important for eyes and make sure that those lenses should not be slept in. Generally, some contacts can be worn for very long hours while others only for short time. Especially, those for cosmetic purposes can be worn for very short time.
In a word, people should be careful in the maintenance and usage of contacts, or some potential eye problems and risks will occur. If any problem occurs, just ask the eye doctors for help.
