A pair of sunglasses is a must for us to have a safe and comfortable summer since the scientists have warned us that strong sunshine and UV rays can do a lot of harm to our eyes. Sunglasses have become more and more popular among common people. But to those who have eyesight problems, wearing sunglasses to protect their eyes is unworkable because common sunglasses do not have the function of eyesight-improving. To solve the problem, some people choose to wear contact lenses first and then plus a pair of sunglasses. In this way, they can both have clear eyesight and protect the eyes from the strong rays at the same time when spending time outside.
However, this method is not so convenient. For one thing, contact lenses are not comfortable enough to wear, especially when wearing for a long time. We must keep special hygienic when wearing contact lenses. For another, contact lenses would easily cause eyesight problems for the wearers. What is more, to some people who cannot adjust themselves to contact lenses, this method is unworkable too.

In fact, there are several other choices such as wearing clip-on eyeglasses or fitovers. To put it simple, Clip-on eyeglasses are eyeglasses that have two pair of lenses on one frame; and fitovers are kind of oversized sunglasses that can be slip over your prescription eyeglasses.
In my opinion, the most convenient way to is to wear prescription sunglasses. As its name suggest, prescription sunglasses are special kind of sunglasses whose lenses have vision-corrective power. Though prescription sunglasses have been in the market for a long time, not all people know them well because of their high prices before.
