Sight Guard is for adults who want to support long-term eye health, especially those over 40 or with a family history of vision concerns. It is meant to complement your doctor’s care, not replace prescribed treatments.
Can I take Sight Guard with my eye drops?
Yes. Sight Guard is a dietary supplement, not a medication. It’s designed to support your overall eye wellness and can be taken alongside most treatments. Always check with your doctor first.*
How do I take Sight Guard?
Just take one capsule a day with food. Morning or evening—it’s up to you.
How long should I take it?
Sight Guard is designed for long-term support. You can take it daily, just like a multivitamin. Most people use it as part of their wellness routine.
