You may wear contact lenses except when wearing the chemical/gas mask. A special pair of glasses/lenses with your prescription are perscribed.
In Basic Training you will be issued a pair of black or brown glasses.
The Army is very strict about the wear of contact lenses. You can wear them in garrison (when at work in the office in the states), but wear is against Army policy in field and deployment environments. The main reason for this is that contact lenses can hold chemicals against the eyes, which would really hurt in a chemical attack!
Wearing contacts or glasses does not preclude military service. Your corrected vision needs to be good enough to pass the physical. And you may be required to wear glasses in boot camp.

Some brands of continuous wear contact lenses that are available on the market are Acuvue and Air Optix. Before buying these it is a good idea to read up on the risks of these lenses so that they may be used safely.
The safety of it is irrelevant - no air force will let you do that.
Longer lasting contact lenses are more durable that daily or weekly wear contact lenses. The most durable set of contact lenses available from 1 800 contacts would be Air Optix.
Air resistance is a contact force because you are in contact with the air in order to apply that force.
I wear contacts, and they only get air under them when you first put them in. Once you blink, the air escapes and they are stuck to your eye. Hardly feel 'em

Decorative contact lenses are often made from cheaper materials. They have a much shorter wear time than prescription lenses and let less air through to the eye. Also- they do not come in the same wide range of shaps and sizes as prescription lenses so you are less likely to find a comfortable fit. Only ever buy contat lenses from an Optical practice and never wear any lenses that haven't been fitted by an Optometrist or qualifies contact lens fitter.
The production of both eyeglasses and contact lenses can contribute to pollution of the environment.,an example is air pollution.
it is contact force
Drag (or air resistance) is a contact force because in the air there is loads of tiny air particles which collides with an object when passing through,slowing it down until it eventually stops and that makes it a contact force. Crystal
