My name is Dr. Toan Thach, OD. I have been with Daly City Target Optical since its inception in 2010 (the very first Target Optical the Bay Area.) I've moved to the Bay Area for this job from my hometown of Long Beach. I've loved every moment of it for the last nine years. Being an Optometrist gives me the chance to meet and engage with so many people from all different social and economic backgrounds. The people of Bay Area are smart, active, passionate, and loving. I can't think of a place I rather be. I want to be a positive force in the community. One way I can achieve that is being a health care provider but I think more accurately is a health monitor-er (if there?s such a word.) Eye examinations can detect so many health issues that most people are not aware of. Being in a commercial place like Target Optical allows me to help people who might have limited or no access to any kind health check. Our health care systems have many flaws, and I'm trying to be a positive force that help address some of that flaws.

Frequently Asked Questions

When should I see an optometrist?When should I see an optometrist?
You should see an optometrist once a year whether or not you believe you need vision correction. An annual eye exam can detect not only eye diseases but also other diseases like diabetes and high blood pressure. Schedule your eye exam today.
What should I bring to my eye exam?What should I bring to my eye exam?
You should bring your vision insurance and medical insurance information to your eye exam. If you currently wear any prescription lenses, bring your eyeglasses, sunglasses, and contact lenses. You should also bring any and all questions you may have. Contact your optometrist if you have specific questions about any additional items you think you may need to bring to your eye exam.
How do I know if my child needs glasses?How do I know if my child needs glasses?
Taking your child to an optometrist for an eye exam is the best way to learn if your child needs glasses. Many children who need glasses aren’t aware that they do. Signs of vision problems in children include sitting too close to the television, squinting, sensitivity to light, difficulty with eye-hand coordination, and avoiding visual activities like reading and drawing. To see if your child needs glasses, schedule your child’s eye exam today.
How does vision change with age?How does vision change with age?
Changes in vision that occur with age include reduced pupil size, dry eyes, loss of peripheral vision, decreased color vision, and vitreous detachment. The most common vision problem that comes with age is presbyopia, which is the normal and unavoidable age-related loss of focusing ability. Different types of lenses can provide help for presbyopia. The risk of developing cataracts, glaucoma, and diabetic retinopathy increases with age too. Your optometrist will discuss any age-related vision problems you’re experiencing at your next annual eye exam.
Who can wear contact lenses?Who can wear contact lenses?
Nearly anyone who needs vision correction can wear contact lenses. Contact lenses can provide vision correction for people with nearsightedness, farsightedness, astigmatism, or a combination of these issues. Finding the perfect lens for you is sometimes a process of trial and error. All of the lens parameters can be finalized only after you’ve worn the successful combination. Schedule an eye exam to talk with your optometrist about whether contact lenses would be a good vision correction option for you.
