Glasses aren't for everyone. Then again, neither are contact lenses. Choosing what's right for you depends largely on your personal feelings about how you look either way and whether you are willing to properly care for whichever one you choose. And of course, there are those who straddle both lines and have glasses and contacts. There really is no ”°right”± choice for everyone, but there are advantages and disadvantages to both in terms of vision quality and health benefits.
Contact lenses, since they sit right on your eye, provide you with clear peripheral vision, something that glasses do not, because glasses sit on the bridge of your nose, and the lenses are a short distance from your eye. Contact lenses are also said to cause less distortion of vision in general for the same reason, because the contact conforms to the curvature of your eye. It does not force your eyes to adjust to the curvature of a lens as glasses do. Contacts also don't provide any vision obstructions, since there are no frames to get in the way.
On the other hand, a piece of plastic sitting right on your eye can pose the occasional problem. If you are prone to dry eyes, contacts can sometimes worsen the dryness. Also, dust and other debris can get stuck to a contact lens and hold it in place, causing serious irritation to the eye. Also, you can take off your glasses to rub your eyes, but rubbing your eyes with contacts in place may cause irritation or dislodge the contact lens altogether. You could damage your eye, the contact, or both.
On the other hand, when you go from cold winter weather outside to warmer indoor areas, glasses can fog up and totally impair your vision. Contact lenses will not do this. Similarly, contacts won't become obscured by rain, snow, sleet or any other kind of precipitation. They also cannot be knocked out as easily as glasses can be knocked off. On the other hand, on rare occasions, a contact might roll up, fold over or get caught up in the eyelid, forcing you to work at getting it back in place, which is a bit more complex than simply putting your glasses back on your nose.
The cleaning of your corrective lenses is another big difference. Eyeglasses only need to be cleaned as often as they get dirty. If they aren't absolutely filthy, you can generally see fine through them. Glasses don't increase the risk of infection or other eye problems. With contacts, you have to make sure you clean them properly every day, store them safely at night, and ensure that your eyes can "breathe" well enough. If you don't pay attention to these concerns, you could end up with problems.
Some research has shown that the myopic process is slowed down somewhat if you have rigid contact lenses. Other than that, most of the differences between the two options are cosmetic and style-related. Choose what works best for what you do and how you like to live. Consult with an optometrist, ophthalmologist or other vision-care professional if you need more advice.
