There are two major types of contact lenses: soft contacts and hard contacts. Soft contacts are the most common day-to-day lenses. They are made of a very flexible polymer material designed to provide comfortable and clear vision. Hard contacts are made of a less flexible polymer material and are often used in specialty cases to provide clear vision. For example, they may be good options for individuals with a high prescription, dry eye disease, keratoconus and for myopia management.

Below is a comparison between soft and hard contact lenses.

Soft Contact Lens

Advantages

  • Better comfort
  • Shorter adaptation period
  • Rarely fall out of the eye making them ideal for sports
  • Available in UV protection
  • Available in coloured options
  • Available in daily disposable options which are convenient and healthy for the eye
  • Available in multifocal options to correct for presbyopia

Disadvantages

  • Vision may not be as sharp for some individuals compared to hard contacts
  • More difficult to handle for lens insertion and removal
  • More prone to drying out causing discomfort for some individuals
  • More susceptible to protein and lipid deposits on the lens causing discomfort over time

Hard Contact Lens

Advantages

  • Excellent vision
  • Excellent oxygen supply
  • Long life span
  • Good durability
  • Easy handling of lens insertion and removal
  • Decreased risk of eye infection compared to soft contacts
  • Available in multifocal options to correct for presbyopia

Disadvantages

  • Less initial comfort
  • Longer adaptation period
  • More easily dislodged from the eye making them not ideal for contact sports
  • Require consistent wear to maintain adaptation making them not ideal for part-time wear
  • More susceptible to debris under the lens causing discomfort
