How to correct our eyesight?

It is common that people may feel eye stressed and tired after working on computers, watching TV for long time. Researches show eye stress is one of the main reasons for eyesight problems. Then we need to find solutions to correct our eyesight. There are the following ways we can use to help us to see clearly:


The most commonly used one is to wear eyeglasses, which is also an old way. People benefit from eyeglasses for long centuries. Nowadays, there are a wide variety of glasses available on the market. The lens is made of different materials, such as polycarbonate, high-index and regular plastic. There are coatings outside in order to be UV resistant and anti-reflective. And there are various frames and colors available for your choice.


While enjoying the clear vision eyeglasses bring to us, people find there are also disadvantage and inconvenience of wearing eyeglasses, for example, wearing glasses will influence their appearance and show their weakness to others, and it is not convenient for people to take some sports with a pair of eyeglasses on their nose bridge, bouncing up and down.


There are many different kinds of lens available in order to satisfy people’s different needs. Soft contact lens is the most commonly used one. They are comfortable to wear as there are high amounts of water rich in oxygen, which can pass freely through our eyes. For people wearing soft contact lens, please keep in mind to clean and maintain it every day, or else, it will be easy to get infected.


Compared with soft contact lens, hard contact lens are less comfortable to wear as it is made of rigid material and allows less oxygen to pass through our eyes. Rigid gas-permeable lens can make up the disadvantage of rigid contact lens, which is made of semi-hard lens and can allow more oxygen to pass through the eye. Rigid gas-permeable lens is often used by astigmatism patients.


As people may feel it is inconvenient and time consuming to clean their contacts everyday, the extended-wear lenses and disposable contact lenses are invented. Extended contacts can be worn continuously without removing it at night. But people with extended contacts are likely to get infection. And disposable lenses can allow people to wear for the limited period of time, such as a day, a week or a month, after it, just throw them away. This kind of contact lens is comfortable to wear as it is made of thinner material with higher amount of water, and another disadvantage of it is it is not easy to get infected.


Besides wearing eyeglasses or contact lenses, people can also resort to Laser eye surgery for help. For certain eye problem, Laser eye surgery can help people to realize their dream of discarding eye glasses in their later life. And it has a high rate of success and less time for recovery. But before taking this surgery, it is advised to visit our eye doctor to do some eye tests so as to see if the surgery is applicable to us.
