Materials Used to Make Contact Lens

When considering buying a pair of contact lenses the first thing to look into is material. There are 4 types of lens, based on the material they are made from, which include:

Soft lens: Soft lenses are made out of a gel-like material that contains hydrogels. They are thin and highly pliable and easily conform to the front surface of the eyeball.
Silicone Lenses: Silicone hydrogel lenses are an advanced version of soft lenses, which allow more oxygen to pass through the lens, into the eye. They are highly popular today for their breathability.

Gas Permeable Lens: These lenses are also known as GP lenses and are rigid, maintain their shape on the eye, and are ideal for astigmatism and other refractive errors of the eye. They have a smaller diameter than the typical lens and are made of oxygen-permeable materials. Most people claim to go through an adjustment period with these lenses, but eventually, find them very comfortable.
Hybrid Contacts: Hybrid contact lenses are made from a combination of GP and silicone hydrogel materials. They have a rigid gas permeable central zone that is surrounded by hydrogel materials. They are designed to offer the comfort of a hydrogel lens and the high corrective ability of a GP lens.

Contact Lenses Based on Wearing Time

Contact lenses are classified into two categories, depending on how often they are worn.

Daily wear lenses: These are lenses that can be worn all day long and are very durable. However, they need to be removed before sleeping.

Contact Lenses Based on Function

Spherical Contact Lens: These lenses have the same lens power throughout the optical portion of the lens. They are used to correct near and farsightedness, or Myopia and Hyperopia.
Toric Soft Lens: Toric soft lenses are made to have different powers in the various meridians on the lens. They are used to correct astigmatism mainly but can also be used at times for Myopia and Hyperopia.
Multifocal Contact Lenses: These include bifocal contacts, and contain different power zones for near and far vision. They are used to correct presbyopia. Some lenses of this type can be used for astigmatism correction as well.
Cosmetic lenses: These lenses come as 0 power lenses and powered lenses as well. They are designed to change the color of the eye. You can find a variety of colors, designs, and funky textures under this category. The lenses used for special effects or Halloween are included in this category.
