According to research, most people with sight problems prefer to wear contact lenses than glasses. It is important to consider certain factors, like the cost, before getting a contact lens. The type of lens you choose and the lens prescription significantly affects the cost.
This article will discuss certain things you need to know about a contact lens, such as the cost, type, safety and others.
How to Use Contact Lenses?
The primary purpose of contact lenses is to correct sight disorders. They are usually prescribed by an eye doctor to correct several kinds of refractive errors and other eye disorders, like:
- Presbyopia (changes to near vision due to aging) 
- Nearsightedness (myopia) 
- Astigmatism (distorted vision) 
- Farsightedness (hyperopia)
People who use glasses to correct any of these vision problems can also wear contact lenses.
Your eye doctor may also recommend contact lenses to facilitate eye healing. Therapeutic lenses or Bandage lenses are types of contact lenses used to cover the surface of the eye and protect the cornea from trauma or surgery. It is important to know that contact lenses are not for everyone. If you have inflammation of the cornea  or dry eye, your eye doctor may advise you not use contact lenses as they can worsen irritation.
