Soft Contact Lenses: Advantages and Disadvantages

11/01/2017

Advantages

• Increased initial comfort
• Less time to get used to
• Lenses are more stable (they are bigger and they usually move less)
• Ideal for sports with risk of impact
• Its use does not usually deform the cornea
• It is more difficult to introduce particles between the contact lens (CL) and cornea

Disadvantages

• Lower duration
• More difficult to manipulate
• They have less gas permeability than modern rigid materials
• Not all optical powers are manufactured
• If they are not special (toric), they do not correct corneal astigmatism greater than 0.75 dioptres.
• The vision obtained with these CLs may be lower than with rigid CLs
• Do not correct irregular astigmatism
• Greater "lipophilia" (they get dirtier)
• Increased risk of contamination
• Cleaning and maintenance more complex and expensive (if done properly)
• Produce more allergic problems
• May cause more eye dryness than rigid
• Less tear exchange when blinking, (they move too little)
• Can easily break (do not pinch)
• They are the ones that cause more eye problems and dropouts
