You should know what is the proper lenses type to your eyes first, and then choose the brand with good quality to buy. 



Firstly, let’s start from how to choose the proper contact lenses type:

There are many different types of contact lenses, we could classify them by materials, wear schedule, and replacement schedule (for soft contact lenses).


  • According to the lens material, contact lenses can by divided by soft of hard (Rigid Gas Permeable)

   - Soft contact lenses are made of soft, flexible plastics that allow oxygen to pass through to the cornea. Soft contact lenses may be easier to adjust to and are more comfortable than rigid gas permeable lenses. Newer soft lens materials include silicone-hydrogels to provide more oxygen to your eye while you wear your lenses. 

   - Rigid gas permeable contact lenses (RGPs) are more durable and resistant to deposit buildup, and generally give a clearer, crisper vision. They tend to be less expensive over the life of the lens since they last longer than soft contact lenses. They are easier to handle and less likely to tear. However, they are not as comfortable initially as soft contacts and it may take a few weeks to get used to wearing RGPs, compared to several days for soft contacts.

  • According to the wear schedule, there are daily wear and extended wear contact lenses.

  - Daily wear contact lenses are designed for using during the day, not for overnight wear.

  - Extended wear contact lenses are available for overnight wear ranging from 1-6 nights or up to 30 days.

  • According to the replacement schedule, soft contact lens wearers must replace contact lenses periodically.

  - Daily Disposable: A brand new pair of lenses can be used each day, but should discarded at the end of each day.

  - Disposable lenses: discard every 2 weeks or sooner.

  - Frequent replacement lenses: discard monthly or quarterly.

  - Traditional (reusable) lenses: Discard every six months or longer

In addition, for those who want to change the color of eyes, you may choose colored contact lenses. For example, if your eyes are blue, wearing a pair of colored contact lenses in brown may make your eyes look more naturally. You may find different options at Gellense.



Secondly, how to choose safe contact lenses with good quality? You should check 5 specifications before purchasing:

  • Oxygen permeability: Oxygen permeability describes the amount of oxygen that is able to pass through the contact lens to reach the eye.

  • Water content: The water content of a contact lens means how much of the contact lens is made up of water. This figure is always given as a percentage.

  • Base curve(s): This describes the curvature of the back surface of the lens. It determines how much the lens that match the natural curvature of your eye.

  • Central thickness: it measures the thickness of the contact lens in the center. The thickness depends on the power of the lens. As a consumer, you do not really need to know exactly about the thickness of the lens, but you need to know exactly about the degree of your eyes, and choose the correct lenses from certain power range.

However, before you buy contact lenses, you should always remember to confirm with a ophthalmic institution or an oculist first, you need know the condition of your eyes first.
