Awareness Tool
What are you spending on glasses?
Cataract surgery is a one-time investment. This tool shows what continued glasses and contact lens spending adds up to — it isn't a price quote.
Projected spending over 15 years
$6,000
Many patients find that, over a 10–15 year horizon, the lifetime cost of updated glasses approaches or exceeds the one-time investment of cataract surgery.
