Contact lenses are special thin plastic discs which rest directly on the cornea. What are they advantages in comparison with glasses?
Advantages of contact lenses
Better correction for certain eye conditions, such as keratoconus and irregular astigmatim.
Thick glasses reduce the side vision in spectacles, because the power is only at the center. The frame also reduces side vision. This problem is solved by contact lenses.
No fogging of vision from humidity and perspiration.
Cosmetic approach to eye problems.
Very comfortable for sportsmen.
Use of optical instruments such as microscope and camera becomes easier.
Soft Contact Lenses
Soft Lenses are made of gel-like plastic and they absorb water as a sponge, which makes the lens more comfortable to wear.

For a lot of people the soft lenses are considerably more comfortable than the gas permeable ones. Especially convenient are disposable lenses. Every morning you apply a new lens and in the evening you throw it away. You don´t have to either to clean the lenses or store them, therefore you don´t need any lans case or cleaning solution..
Advantages
More comfortable so fits easily.
Can be worn part time.
Does not pop out so better than hard lenses for active and sports related lifestyle.
Remains centrally located in the eyes.
Dust does not get trapped so comfortable even in dusty atmosphere.
Disadvantages
Need of proper care and cleaning.
Vision may not be as sharp as hard lenses especially with astigmatism. However these days toric soft lenses are available for astigmatism which are even more expensive..

Constant presence of the edge of lens and the frame. Reflections off the backside of the lens occur in specific light conditions. | With contacts, no annoying obstructions or reflections are present. |
Presence of uncomfortable burden on your face and ears. Periodic need for tightening or other adjustment. | No weight and resulting discomfort. No frame constantly slipping down your nose. |

Both require careful handling and cleaning.
Glasses have to be wiped several times a day, while contacts need varying degrees of care, depending on the type. The cleaning is usualy fast and easy.
Both can correct astigmatism.
Astigmatism, an irregular, vision distorting cornea shape, is something that many people think only glasses can correct. But nowadays contact lenses do an outstanding job of correcting astigmatism.
Both are affordable.
When you consider that you wear glasses or contact lenses every single day of your life, the amount you spend on them is far less than some other items of daily use. Considering how important they are to the quality of your life, they're invaluable.
Since glasses have few, if any, advantages over contact lenses, you may decide to start using contact lenses.
If you're still undecided about which vision option is best for you, talk about it with your ophtalmologist.
