WELCOME Welcome Play Video Welcome Play Video Share Whole Channel This Video Facebook Twitter Pinterest Tumblr Copy Link Link Copied Share Channel Info Close Meet Our Eye Care Team Dr. Ngo Optometrist Dr. Ngo is a native of the San Francisco Bay Area and has over 20 years of experience in the field of eye care. He attended the University of California, at Davis where he completed his Bachelor of Science degree in Food Science. Initially his interest in Food and Wine led him to pursue this career path. He imagined working at a tasting lab creating new Umami flavors for food or even at a winery in Napa or Sonoma refining Merlot or Cabernet vintages. Finally after several visits to the Eye Doctor peaked his interest in vision and the science that was used to correct it. This led him to pursue his doctorate degree at The Ohio State University School of Optometry in Columbus Ohio. ​ During his years in Columbus, he completed clinical rotations at the Dayton Veterans Affairs Medical Center in Dayton Ohio, where he specialized in ocular disease and pathology.  Outside of academics, Dr. Ngo was also a member of the Epsilon Psi Epsilon (EYE) fraternity which focused on volunteer and community service. He began practicing in Palo Alto in 2007. Dr. Ngo enjoys his clinic days in Palo Alto because of the diverse population of patients often composed of leaders and innovators from all walks of life. Dr. Ngo loves to spend time outdoors hiking with his wife Betty and 4 year old son Tyson. The family also loves the beach and recently took up paddle boarding! In the winter they head to the mountains of Lake Tahoe for some fun in the snow for Tyson and hopefully some snowboarding for ONE of the parents. The family recently welcomed a new baby girl Abby to join in on their future  adventures . Dr. Santa Maria is a proud Bay Area native. She received her B.S. in Integrative Biology from UC Berkeley. She returned to her college alma mater to obtain her Doctor of Optometry degree with clinical honors. She then completed her residency training at the Veterans Affairs Hospital in Palo Alto, where she specialized in ocular disease, low vision, and specialty contact lenses. ​ Dr. Santa Maria is dedicated to providing excellent, individualized patient care, and she is passionate about enhancing her patients’ quality of life through the best possible vision. In addition to working in private practice, Dr. Santa Maria also dedicates her time teaching and mentoring fourth year optometry students. Dr. Santa Maria’s personal interests include spending quality time with family and friends, traveling, and experimenting in the kitchen. Dr. Janelle Santa Maria Optometrist Dr. Teresa Nguyen Optometrist Dr Teresa Nguyen is a south bay native who's happy to be back in the bay. She attended UC Davis where she received her BS in Psychology with an emphasis in Biology. During her time in Davis, she did research in visual cognition and perception, which sparked her interest in optometry. She then traveled to Philadelphia to pursue her doctorate degree from the Pennsylvania College of Optometry. She is a member of the American Optometric Association, California Optometric Association, and Santa Clara County Optometric Society.    Outside of clinic, Dr Nguyen enjoys reading, backpacking, and indoor bouldering. She also spends time working with children in the foster care system as she is passionate about reducing the long-term effects of adverse childhood experiences. Her other hobbies include NBA/WNBA basketball and live comedy.  Dr. Ngo O.D. and Associates 855 El Camino Real suite #103  Town and Country Village next to Douce France Bakery.  Palo Alto Ca 94301 (650) 326-9111   Palo Alto Appointment Milpitas Appointment Office Hours Monday Closed Tuesday 10am-6pm Wednesday 10am-6pm Thursday 10am-6pm Friday 10am-6pm Saturday 10am-5pm Sunday Closed Copyright Dr. Ngo Optometrist  Webmaster Login bottom of page --> Eye Links Online Color Vision Exam Virtual Simulator Test Warby Parker Dr. Ngo O.D. and Associates Palo Alto top of page Palo Alto (650) 326-9111 Milpitas   (408) 945-0100 Dr. Ngo O.D. and Associates Serving the Bay Area since 2007 with 2 convenient locations Book Online HOME ABOUT SERVICES CONTACT LENSES EYEWEAR GALLERIA REQUEST APPOINTMENT EYE LINKS EYECYCLOPEDIA Use tab to navigate through the menu items.

Comprehesive Eye Care For Your Family Our practice was designed and built around our patients, and we strive to provide the best possible service and care. Our office uses the latest technologies and techniques to give you the best and most comfortable vision at work and at play. Dr. Ngo recommends annual eye exams to maintain optimal visual health. By looking inside your eye we can observe  diseases before they affect your vision. Most eye diseases change slowly  and are painless so you don't notice until you have lost some sight. We  have on site visual field testing with the Carl Ziess Frequency Doubling (FDT) visual field perimeter. This advanced technology allows us to detect Glaucoma much earlier than other visual field analyzers. We also offer advanced imaging and diagnostic techniques to capture detailed photos of the retina where many systemic conditions such as Diabetes and Hypertension can be seen.  ​ We provide Specialty contact lens services such as Scleral Contact lenses for the treatment of corneal irregularities such as Keratoconus. We also offer contacts for slowing down the progression of Myopia (Myopia Control). Studies show that we can reduce the advancement of nearsightedness up to 50% with these types of treatments. We also offer FREE Lasik evaluations as well! Because we know how much your eye health and appearance can mean to the quality of your life, we are committed to excellence in servicing your complete eye care needs. We have  a highly trained staff that guarantees that you will be treated with fairness, courtesy, and respect. If you're looking for quality care with a personal touch, we hope you'll give us a call. For your convenience our Optometry office is open evenings and weekends! ​ Why Are Annual Eye Exams Important?  Routine eye exams are important — regardless of your age or your physical health. During a comprehensive eye exam, your eye doctor does much more than just determine your prescription for eyeglasses or contact lenses. He or she will also check your eyes for common eye diseases, assess how your eyes work together as a team and evaluate your eyes as an indicator of your overall health. Also, eye doctors often are the first health care professionals to detect chronic systemic diseases such as high blood pressure, diabetes, cholesterol, and auto-immune conditions.  ​ Eye exams for children also are very important to insure normal vision development and confirm that children have the visual acuity and vision skills required for schoolwork and other activities. Children don’t always know what “normal” vision looks like, so they’re unlikely to complain of vision problems. However, because vision is so closely linked to the learning process, undetected learning-related vision problems can lead to trouble with schoolwork. If your child is performing poorly at school, be sure to have his or her eyes examined to ensure optimum vision for learning. Myopia Control Does your prescription seem to increase every year?

EYECYCLOPEDIA ​       AMBLYOPIA -- Amblyopia, also known as lazy eye, is a vision problem that affects just two to three percent of the population, but if left uncorrected, it can have a very big impact on their lives. Central vision does not develop properly, usually in one eye, which is called amblyopic. A related condition, strabismus, sometimes causes amblyopia. Untreated amblyopia may lead to functional blindness in the affected eye. Although the amblyopic eye has the capability to see, the brain "turns off" this eye because vision is very blurred. The brain elects to see only with the stronger eye.   ANISOMETROPIA -- A condition of the eyes in which they have unequal refractive power. ANTI-REFLECTIVE COATING -- A coating on the front or back of the lens, which minimizes the glare for patients who are extremely bothered by glare. APHAKIA -- The absence of the lens of the eye. ASTHENOPIA -- Eyestrain. ASTIGMATISM -- Objects are blurred at all distances because the shape of the cornea is not uniform. BIFOCAL LENSES -- Lenses containing two focal lengths, usually arranged with the focus for distance above and near focus below. BLEPHARITIS -- Blepharitis is the general term for inflammation of the eyelids. This may occur from irritations and allergies, insect bites, infections, etc. Blepharitis is an eye infection which produces symptoms of sticky, crust and reddened eyelids. This eye infection is caused when excess oil is produced in the glands near the eyelashes creating a growing environment for bacteria. Blepharitis may vary from a chronic, mild condition to a severe form with ulceration of the lids and damage to the eyes. Signs and symptoms may include: itching, swelling, redness, scaling and crusting of the lashes and lid margins. Blepharitis may also be part of more widespread skin conditions including seborrhea, acne, and rosacea. This condition is easily treated and rarely threatens sight, but it may cause the loss of eyelashes. Mild, nonspecific or seborrheic varieties may simply require warm soaks and daily lid hygiene. Other infectious varieties of blepharitis may require antibiotics and/or cortisone creams or even oral antibiotics all of which should only be used under medical supervision. CATARACT -- A cataract is a gradual clouding of the eye's natural lens. The formation of a cataract occurs during the normal process of aging. Although cataracts may affect people of any age, they are most common in older adults.   CHALAZION/CYSTS/STYES -- Small lumps or bags filled with fluid that form on the upper or lower eyelids are called cysts. A cyst is caused when an oil-producing gland in the eyelid becomes blocked and in some cases, infected. There are times when a cyst can enlarge to the point that vision is affected. And sometimes a cyst will remain small and disappear on its own without the need for medical treatment. There are also times when a cyst will remain and enlarge to a size that causes pressure on the cornea. This can cause a slight impairing of the vision. Treatment of a cyst may consist of applying a warm compress to the eye or your doctor may prescribe antibiotics. In some cases, surgery may be needed to remove the cyst. A chalazion cyst is an inflammation and swelling in one or more of the oil glands of the lid margin (meibomian glands). An acute infection of a meibomian gland is called an acute chalazion or internal hordeolum. This type of chalazion is often loosely referred to as a "sty." A sty is an infection that can occur at the base of the eyelashes. Acute chalazions often respond well to hot compresses and the instillation of antibiotic drops or ointment.   COLOR BLINDNESS -- Color blindness is not a form of blindness at all, but a deficiency in the way you see color. With this vision problem, you have difficulty distinguishing certain colors, such as red and green or blue and yellow. Red-green color deficiency is the most common form of color blindness; a less common form is blue-yellow color deficiency. COMPREHENSIVE EYE EXAMINATION --This examination service provides evaluation of the complete visual system. Comprehensive services constitute a single service entity, although it is not necessary to perform all services in one session. CONJUNCTIVITIS (Pink Eye) -- The mere mention of the words "Pink Eye," gets immediate attention from parents and teachers everywhere, largely because "Pink Eye" is highly contagious, and is often passed from one child to another. The medical term for pink eye is conjunctivitis. It is important to note that all cases of conjunctivitis are not "pink eye" and there is no need concern about the contagion of noninfectious forms of conjunctivitis such as allergic, chemical or environmental varieties. "Pink Eye" is an inflammation of the conjunctiva, or the transparent membrane lining the eyelids and the white of the eye. Redness or itching of the eye, blurred vision, sensitivity to light, and a gritty sensation in the eyes are all indications that conjunctivitis might be present. Thick yellow secretions may form a crust during the night, making the eye stick shut in the morning. The infection is caused by bacteria or virus and is very contagious. Allergies can also cause conjunctivitis. Depending upon the cause, treatments can vary. Hot or cold compresses or medicated eye drops or gels usually are the recommended course of treatment. CONTACT LENSES -- Lenses which fit directly on the eyeball under the eyelids. CORNEA -- The cornea is the clear outer covering of the eye. The cornea covers the colored portion of the eye and protects it, much like a crystal covers the face of a watch. Light rays enter the eye through the cornea and are later interpreted by the brain.   DIABETIC RETINOPATHY -- Diabetic retinopathy is a complication of diabetes caused by the deterioration of blood vessels nourishing the retina at the back of the eye. This condition can cause blindness in people under age 65 and the longer a person has diabetes, the greater the chance of developing this complication. There is no pain associated with diabetic retinopathy. Gradual blurring of vision may occur, but changes in the eye can go undetected without a medical eye exam. In many cases, treatment may not be required; in others, laser treatments may be recommended to halt further progress of the disease. Early diagnosis and treatment are vital to preventing visual loss from diabetic retinopathy. DIPLOPIA -- Diplopia is more commonly known as double vision. Each eye has six different muscles responsible for moving it in various directions. That means the brain has to control 12 eye muscles simultaneously. The control of these 12 muscles is coordinated through a system of nerve connections that course throughout the brainstem. Not surpisingly, such a complex system is vulnerable to a large number of disease conditions. Three different cranial nerves supply the eye muscles of each eye, and anything causing damage to them can cause double vision. Strokes, trauma (injury) and brain tumors are some of the things that can damage these cranial nerves. Diabetes is also a common cause of double vision and occurs when the damage caused by diabetes causes a small stroke to one of the cranial nerves. Any disease process that involves the eye muscles themselves can also cause double vision. Interestingly, children born with eye alignment problems, such as esotropia ("crossed eyes"), do n --> Palo Alto Menlo Atherton | Stanford Eye Exam | T & C Village Optometry | Dr. Ngo O.D. and Associates Optometrist top of page Palo Alto (650) 326-9111 Milpitas   (408) 945-0100 Dr. Ngo O.D. and Associates Serving the Bay Area since 2007 with 2 convenient locations Book Online HOME ABOUT SERVICES CONTACT LENSES EYEWEAR GALLERIA REQUEST APPOINTMENT EYE LINKS EYECYCLOPEDIA Use tab to navigate through the menu items.

Aren't all contact lenses the same?  I have dry eyes and allergies, am I a candidate for contact lenses? ​ If you are wearing contact lenses that are more than a few years old you may benefit from a contact lens re-evaluation to see if you are wearing the best type of lens for YOUR eyes. Incredible advances have emerged in biomaterial engineering and surface chemistry, allowing scientists to generate a new breed of contact lenses called silicone hydrogel . The development of highly oxygen-permeable silicone hydrogel lenses is the biggest breakthrough in lens material technology since soft lenses entered the market in the 1970s. Not only do silicone hydrogel materials provide ocular health benefits, they also allow people to wear contact lenses longer, making continuous wear a healthier option.    Traditional soft contact lenses are made from hydrogel polymers (soft, water-containing plastics). The plastic itself is not oxygen permeable, so the water performs the job of carrying oxygen through the lens to the eye. But water can carry only so much oxygen — and the more water a lens contains, the greater its tendency to dehydrate after long periods of wear.  Silicone is oxygen permeable. So silicone hydrogel lenses use both their water and polymer content to transmit oxygen to the eye. ​ ​ ​ ​     Silicone hydrogel lenses  are healthier than conventional soft lenses because they allow up to 6 times more oxygen to pass through them and increased oxygen transmission results in better overall eye health. Advantages of silicone hydrogel lenses over conventional soft lenses include: more resistance to protein deposits, less drying of the lenses, and lower risk of eye infection. This advancement has allowed even dry eye patients the ability to wear contacts and to finally be glasses free safely and comfortably!  ​ ​ I wear progressive glasses, are there contact lenses that can help me read without having to put reading glasses over my contacts?  Our office carries many brands and types of the latest disposable  silicone hydrogel contact lenses such as Johnson and Johnson Acuvue Oasys , Coopervision Myday and Biofinity, Ciba Dailies Total One, and many more.  We are experts in helping patients who are having difficulty reading up close with their current contacts. We specialize in Bifocal and Mono Vision contacts to help you see your computer and phone without the need for reading glasses over contacts. We also treat corneal irregularities such as Keratoconus using the Jupiter Scleral Contact Lenses. ​ We also offer contacts for slowing down the progression of Myopia ( Myopia Control ). Studies show that we can reduce the advancement of nearsightedness up to 50% with these types of treatments. We also have colored contact lenses to enhance or change your eye color! We have all the latest Freshlook contact lenses, including Freshlook Colorblends! We also now carry the new light adaptive Acuvue Oasys Transitions contact lenses with UV protection!
