Contact lenses have replaced the traditional eyeglasses at a large extent. They differ a lot from the eyeglasses are provide many facilities that any spectacle cannot provide. These lenses are advantageous over eyeglasses on various aspects. But, there are also some disadvantages that a person has to face while using contact lenses. Here we are going to compare between contact lens and eyeglasses. Everyone knows what an eyeglass is and what its use are. But, there are also few people who do not know much about contact lenses.

Contact lens is a soft plastic plate placed in the cornea of human eye. It works same as that of an eyeglass, but is more advantageous than the traditional eyeglasses. Contact lenses are light-weight and weigh almost nothing, they are fully transparent. When a person wears a contact lens on the cornea region of the eye, it cannot be distinguished. Some contact lens manufacturing companies use tints of color on these lenses, so that they can be visible while cleaning. Since, a contact lens has direct contact with the cornea; there are certain possibilities of eye injury (if certain precautions are not taken). The eyeglasses are safer in such cases, but if a person faces any kind of accident, then also his eyes can get totally damaged by the broken glass pieces of the spectacle. The contact lenses are much better in such cases.

For this kind of reason, people tend to use contact lens more than spectacles.

However, there are some problems about the contact lenses. Most importantly, it has to be cleaned regularly. Most people do not take much care of their lenses and are ignorant about it.

However, contact lens cannot be cleaned like the glass spectacles; it should be cleaned very carefully. There are also certain limitations for cleaning a lens.
