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
