Soft contact lens and Hard contact lens
Today, many people use contact lens. Contact lens is useful for people with bad eyes. Contact lens has two types. It is soft contact lens and hard contact lens. Although, they have similarities, they also have a number of differences.
First, let’s compare the two. Both soft and hard are lens for bad eyes person. Like soft, hard can see if bad eyes person don’t put on glasses.
Contrasting the two lenses, the first things you’ll notice is the difference in size. Soft is bigger than cornea, while the size of hard is smaller than cornea. So, hard is apt to drop and lose. On the other hand, soft doesn’t drop much. But, small doesn’t have only bad thing. As hard is smaller than cornea, hard can get many oxygen. Soft can’t get oxygen much.
Unlike hard, you don’t hurt when you put on soft lens. On the contrary, you feel prickly when you put on hard.
Also, one excellent feature of hard is durable. So, hard can use for long. Soft is tear easily. And, hard is easy to improve. The improve way is only soak in washing liquid. But, soft must washing and boiling. This is very troublesome. You may be disliked soft for this reason.
Both, soft and hard have merits and demerits. I use soft present. I don’t use up to now. Using hard may good choice.
