People who are in need of eye glasses must receive eye check and get an eye prescription before buying. Similarly, eye examination is also essential if people want to buy contact lenses. Comparatively speaking, eye exam for lenses will take much longer time than that for glasses. And it is strongly suggested to make an appointment before the exam.
The whole eye exam process is very complex. Eye doctors will first decide whether or not the receivers are good candidates by asking a lot of questions. People in certain eye condition can not wear lenses. After that, an eye check will be operated- this is the same as in eye exam for glasses. The eye doctors will make some observations on the eyes and their structures and reaction to certain drops, etc. After that, the eye condition of the patients can be well detected.
When the patients are proved ideal candidates for lenses, they will receive some examination for lenses. Unlike exam for glasses, this exam is really very complicated and personalized- patient’s eye balls, sizes, and other factors will all be measured in the process. Of course, the whole process is operated with the help of some high-tech equipments, which can accurately measure the sizes and other data.
Later, some other aspects, like how health the corneas are, will all be measured and tested. For example, in order to know how patient’s eyes react to lenses, its moisture will also be measured. And the result is every patient’s contact lenses are completely individualized and can not be worn by others.
After that, when every data is measured, the eye doctor may suggest patients to try on some trial contact lenses. This process is very important, for it determines whether patients can get used to lenses or not. Of course, the trial process is also time-consuming. Usually, people have to try on many pairs until their get the ones fit them most. While trying, eye doctor will also offer some guidance on how to insert and remove lenses. Other suggestions on eye health and lenses maintenance will also be given in details.
When people have brought their lenses home, they should also revisit their eye doctors regularly, until their eyes completely adapt the lenses and they know how to use the lenses. If there is anything unusual, just contact eye doctors for help.
