For people who have eyesight problems, if you want to get rid of eyeglasses at least for a while, you might like to try contact lenses. Some may be afraid of wearing contact lenses because they directly make contact with your eyes, one of the most important organs. I cannot tell you that there is no risk in wearing contact lenses, but if you are hygienic enough and are careful about wearing them, it will be safe. If you want to try contact lens, but the optician did not advise you about them, don’t be shy, just ask them about trying contact lenses.

  
Contact lenses can increase your sight range. Normally you can see clearly only within the eyeglass border. But using contact lens, you can see clearly over the full range, because the lenses attach to your eyes. Also the size of what you see is not distorted. Normally when you wear a concave lens, the things you see are smaller than what they are. For people who have a highly different lens power between the two eyes, they may have headaches, but contact lenses can solve this problem. Contact lenses also make you more attractive, without eyeglasses.  And for athlete, it will be more comfortable and convenient.

You also have to accept the difficulties in wearing contact lenses. Contact lenses may not last long. They may lost or be torn. You have to practice wearing them and taking them off. You have to take good care of them, clean them thoroughly, and put them in the solution, etc. For best results, you  should wear them only 8 hours per day, except for the extended wear contact lens. After you take the lens of and then wear an eyeglass, at the first glance the sight may not so clear. It will take a few seconds to adjust the eyesight back to glasses again.

However, if you still want to use contact lenses, your eyes must be diagnosed by an ophthalmologist (the doctor) before wearing a contact lens. He can tell you if you can wear contact lenses or not. And the ophthalmologist will also recommend the suitable contact lens type for you.
