Eyecare in Eastvale, CA


At One Vision Optometry, we are committed to continuing to learn and expand our knowledge in providing the best possible eyecare to all our patients. We utilize the best and latest technology to detect, diagnose, and manage all your vision needs. We provide the following services at our office:

Adult Comprehensive Eye Exam

Adult Comprehensive Eye Exam

Visual system and ocular health change as people age. Often, these changes may not have any signs or symptoms for many people. Some of these changes, when undiagnosed, can lead to visual discomfort, unexplained headaches, poor work performance, and even permanent vision loss. We recommend that all adults have yearly eye exams so that we can detect and monitor all visual needs and ocular health conditions. Our comprehensive eye exam includes screening for visual problems, electronic eyestrain conditions, diabetes, hypertension, cataracts, glaucoma, macular degeneration, and retinal eye diseases.

Children Comprehensive Eye Exam

Children's Comprehensive Eye Exam

Many of us believe that all children are born with perfect vision and eyes. While this is correct in most cases, there are many children who are born with less-than-perfect situations. When undetected, they can develop lazy eyes, irreversible vision impairments, delay development, or perform poorly in their schoolwork and social skills. We recommend that all children have yearly eye exams so that we can detect and monitor their visual needs and performance.

Ocular Health Screening

At One Vision Optometry, we prioritize safeguarding your eyes and overall health. Our comprehensive eye examinations, including vital retinal health screening, aim to identify early ocular issues that may lack noticeable symptoms. Undetected signs could lead to complex and potentially sight-threatening medical conditions.

Optomap retinal technology, recommended annually by our Optometrists, offers advanced imaging for quick and accurate detection of eye problems. This technology is particularly effective in imaging children's retinas. If abnormalities are found, our doctors may perform eye dilation for further evaluation and discuss management strategies.

While some insurances cover this procedure annually, others require a medical diagnosis. For those without coverage, the procedure fee is $45. Please inquire with our staff for more information.

Contact Lens Fitting And Evaluation

Contact Lens Fitting & Evaluation

Contact lenses allow many people with visual problems and active lifestyles the freedom from having to wear glasses all the time. Contact lens fitting and evaluation are in addition to a comprehensive eye exam, as this procedure requires extra time and follow-ups. Contact lenses come in many different brands and forms that can correct multiple visual problems from spherical, astigmatism, monovision, and multi-focal.

Orthokeratology | Corneal Refractive Therapy (CRT)


Corneal Refractive Therapy -CRT

This is an FDA-approved non-surgical treatment that uses precise, specialized shaped contact lenses to temporarily reshape the cornea while patients sleep in order to eliminate nearsightedness, myopia, and mild astigmatism. Patients who are fitted with CRT lenses can enjoy good distance vision without wearing eyeglasses or regular contact lenses throughout the day. While not approved at this time in the United States for this purpose, numerous studies worldwide indicate that this type of lens can help greatly stabilize myopia progression in many children whose eyesight continues to deteriorate every year.

Keratoconus Scleral Contact Lens Fitting

Keratoconus Scleral Contact Lens Fitting

Sclera lenses are specially designed gas-permeable contact lenses that vault over the entire cornea and rest on the white sclera of the eyes. They are used mostly for patients who are diagnosed with challenging conditions such as keratoconus, corneal ectasia, post-corneal transplant visual impairments, and severe dry eyes. These patients usually enjoy superior comfort and excellent vision with scleral contact lenses over other lenses available today.

Gas Permeable Contact Lenses Fitting

Gas-Permeable Contact Lenses Fitting

While most people enjoy the comfort and convenience of soft disposable contact lenses, there are still many people who want the crisp and clear vision that gas-permeable contact lenses can offer. Dr. Le enjoys fitting this type of lens at her office.

Diabetic Eye Examination

Diabetic Eye Examination

This exam specifically emphasizes the monitoring and management of diabetes and changes in the eyes. Since diabetes is the leading cause of blindness in the United States, it is recommended that patients with diabetes have their eyes checked yearly or every six months, depending on the severity.

Macular Degeneration

Macular Degeneration

Macular degeneration is a deterioration of the central portion of the retina, the inside layer of the eye that records the images we see and sends them through the optic nerve from the eye to the brain for processing. The macula, or the center of the retina, is responsible for focusing central vision in the eye and controls our ability to see and process information.

Although macular degeneration can occur naturally through old age, living an unhealthy lifestyle increases your probability; smoking, being overweight, genetics, and exposure to blue light play a crucial role in the likelihood of being diagnosed with this disease.

To detect whether or not you may be suffering from macular degeneration, we perform a variety of macular tests and will determine your prognosis during your appointment.

Dry Eyes Management

Dry Eyes Management

Living in the Inland Empire, many of us are familiar with dry eyes as a major problem due to our dry, windy climate; however, many people are not aware that too much electronic screen viewing can cause dry eyes as well. Acute dry eyes, when left untreated, can lead to chronic problems in many cases and be difficult to manage. Dry eyes' symptoms are often confused with other ocular problems and can be easily misdiagnosed. The symptoms range from red, irritated eyes with sandy and scratching feelings to blurring vision, contact lens intolerance, and severe eye pain and headaches. Consult with Dr. Le if you believe you are experiencing dry eyes.

Computer Vision Syndrome

Computer Vision Syndrome

Most of us, if not all, are living in a new normal world where electronic viewing is a part of our daily life: from PCs to tablets to smartphones. For most of us, surviving without one of these each day seems impossible and unavoidable; however, many people are unaware of the effect and danger of the continuous closed-up viewing of our visual systems and how it can change our eyes forever. This is especially true in our young children's eyes. Having gone through the problem as a child and young woman in college, Dr. Le is aware of these effects on our visual systems and has determined to educate all her patients to understand the problem and what they can do to help protect themselves from worsening.
