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.
