True
Non-corrective lenses do not affect the direction of the rays of light. What they do affect is the composition of the light. Non-corrective lenses are filters blocking out some wavelengths of light in order to do not reach the human eye.
The usual treatment for farsightedness is corrective lenses (spectacles or contact lenses).
Corrective lenses
We use corrective lenses in spectacles. Near sight is corrected with diverging lenses and far sightedness with converging lenses.

Wearing glasses does not make your eyes worse. Glasses, contacts, and all corrective lenses will only make your eyesight better, when you wear them as prescribed.
Only at extreme G-loads will corrective lenses become a problem. During normal aerobatic maneuvers, it is uncommon for pilots to be subjected to more than about 3 G's. This is usually acceptable is as far as contact lenses or eyeglasses goes. It should be noted that the air force allows fighter pilots to use corrective lenses, although if contacts are to be used, soft-contact lenses are required.
Eye care professionals most commonly correct myopia through the use of corrective lenses, such as glasses or contact lenses. It may also be corrected by refractive surgery, though there are cases of associated side effects. The corrective lenses have a negative optical power.
You need to wear corrective lenses.
AnswerSince contact lenses are corrective lenses for contact with the eye, I presume you mean the general case with optics.The answer is that lenses can be in contact with each other and often are. But it is very difficult to put two lenses into contact without a gap, so these lenses are usually bonded together with optical cements.Lenses have been made with liquid elements between lenses, too.
