Some people are not suitable for multifocal lenses because the optical compromises could worsen their vision or daily comfort.
Eye and health reasons to avoid them
Multifocal lenses split light between different focus points, which can reduce contrast. In eyes that already struggle, this may cause poorer overall vision.
- Significant macular disease such as advanced macular degeneration
- Moderate or advanced glaucoma with existing field or contrast loss
- Irregular corneas, marked scarring, or significant higher-order aberrations
- Severe dry eye that is difficult to control
- Previous retinal surgery or major retinal scarring affecting central vision
Personality and lifestyle considerations
Some people find any visual phenomena unacceptable. If total clarity in challenging conditions is essential, multifocal lenses may not be the best choice.
- Very sensitive to glare, halos, or small visual imperfections
- Frequent night drivers, pilots, or professional drivers needing optimal contrast
- Risk-averse individuals uncomfortable with permanent optical compromise
- People happy in glasses who do not mind wearing them most of the time
- Anyone expecting guaranteed perfect vision without glasses in all situations
