Eye patches are generally worn for medical reasons. It is important to note; diagnosis is made for the wearing of an eye patch by a doctor. There are many reasons doctors diagnose wearing eye patches, and they are usually made of leather or a cloth material which is held in place with a string or an elastic band. Other bandages are made of plastic that is kept in place by clipping them to the lens of a pair of eye glasses, and there are still others that are made of adhesive that is placed over the eye like a band aid.
Reasons for Using an Eye Patch
Medical issues like “lazy eye” or Amblyopia, which is a situation of one eye not functioning as it should, is one reason. By wearing the eye patch on the good eye, it gives the Amblyopic eye the chance to strengthen the muscles and it gets accustomed to doing the work as well as the good eye. This treatment is generally for children when this condition is discovered. Some kids have issues with being teased by their peers about having to wear a patch, so other treatments may be used to correct this condition.
Double vision or Diplopia is another medical condition that warrants the use of an eye patch. The symptoms are blurred or double vision. This condition occurs with people who suffer from Vertigo, dizziness, and nausea. Other medical conditions that warrant having to wear an eye patch include, having lost an eye in an accident or losing an eye from a disease. There are also other reasons that people wear eye patches that are not necessarily medical, but practical.

Practical Reasons for Wearing an Eye Patch
It is known that commercial airplane pilots used to wear an eye patch to cover their eye when having to fly in the dark; it helps their eye to become accustomed to the dark especially when flying over cities that are brightly lit and have the need to see the instruments in the dark cockpit. This practice helped pilots, but it is advised by the FAA nowadays that pilots close one eye while flying at nights and use a light in the cockpit. This exercise helps to preserve their night vision for reading instruments. Military pilots will wear special eye patches lined in gold or lead which could potentially protect their eyes from particular types of attacks while flying through dangerous territories.
Historically, eye patches were worn by pirates for the same reason as pilots to get their eyes acclimatized to the dark if they have to go below deck. The blacksmiths of old would wear eye patches as well to protect their eyes from the damage of sparks when working.
