If you need vision correction and are wondering if contact lenses are a good alternative for you, there are a few things you need to take into consideration.
Think about your lifestyle. For example, do you participate in any sports? If you jog, do aerobics, or other jarring sports, you will likely find glasses cumbersome. They will have a tendency to slip and fall off, or you will have to purchase a strap to keep them on. Even then, they may fog up when you sweat or sweat may drip onto them. Contact lenses will save you all this trouble. You will be able to see clearly and wont have to worry about them falling off. If you play contact sports, you may not be able to wear glasses, or you may have to invest in goggles large enough to cover them, or even more costly, prescription safety glasses. If you are a swimmer however, contact lenses may not be a good choice, as you could lose them if you open your eyes underwater.
Another factor to bear in mind is maintenance. Glasses will get smudged and will need to be cleaned occasionally to optimize your ability to see through them, but keeping contact lenses clean is critical not only for your vision, but for your health...
