Difference between an ophthalmologist, optometrist, and optician
Selecting the right eye care professional to care for your eyes is crucial. There are three types of eye care experts: ophthalmologists, optometrists, and opticians, and each has a distinct role in providing eye care services to consumers.
- Ophthalmologist: An ophthalmologist, an eye M.D., is a medical or osteopathic doctor specializing in providing medical care and treatment for vision and eye-related issues. Their extensive training of at least eight years beyond college and their requisite license enable them to perform surgeries, offer diagnoses, prescribe eyeglasses, and fit contact lenses to correct vision problems. Ophthalmologists are also actively involved in scientific research to better understand the causes and cures of eye-related diseases and vision disorders. Ophthalmologists can specialize in specific medical or surgical eye care areas, known as subspecialties. These subspecialties include glaucoma, retina, cornea, pediatrics, neurology, plastic surgery, and others. To become a subspecialist, ophthalmologists complete an additional one to two years of training in their chosen area of expertise. Subspecialists can care for more complex or specific conditions in specific eye areas or certain groups of patients.
- Optometrists: These eye care professionals offer various services. They offer comprehensive eye care services, including eye exams, vision tests, prescribing corrective lenses, detecting abnormalities, and managing vision changes and eye diseases with medication. To become an optometrist, one must first complete three or more years of college, followed by a four-year optometry school program to earn a Doctor of Optometry (O.D.) degree. Optometrists are licensed to practice optometry and help people maintain good eye health.
- Opticians: These highly skilled technicians specialize in designing, verifying, and fitting eyeglass lenses, frames, contact lenses, and other devices to correct visual impairments. They rely on prescriptions from ophthalmologists or optometrists to perform their work, but they do not test vision or prescribe medications for eye conditions. It is also important to note that opticians are not certified to diagnose or treat eye disorders.
Tips to take care of your eyes and overall health
The last two years of COVID-19 have accelerated exposure to digital devices, resulting in prolonged screen time, a growing concern for overall health. Electronic devices, including computers, laptops, smartphones, and tablets, have seen a tremendous increase in use by adults and children. Excessive screen time can adversely impact your physical and mental health. It also has a significant effect on your eye health. Since digital devices are here to stay, let us look at how to care for our vision health.
It is said that protecting your overall health helps to keep your eyes healthy. Therefore, encourage your kids to choose healthy lifestyles and adopt them.
A healthy lifestyle includes eating fresh and healthy foods, which reduce your risk of diseases and conditions that impair your vision and cause numerous eye problems. While keeping that in mind, start incorporating the following things into your lifestyle for healthy eye vision:
- Eat healthy foods: Ensure you consume plenty of dark leafy vegetables, including kale, spinach, and collard greens. Leafy vegetables are best for your eyes' health. Inclusion of green foods in diet will give your eyes a good vitamin boost. Also, consume fish like salmon, tuna, and halibut as they are high in omega-3 fatty acids.
- Be active: Including light exercise or yoga in your daily routine is crucial to maintaining a healthy lifestyle. Being physically active helps you stay healthy by pushing away the risk of several diseases that can cause your overall health to deteriorate. Diabetes, high blood pressure, and heart conditions can significantly impact your eyes. Being active can lower the risk of health conditions that can affect your vision health and cause several eye diseases. A brisk walk for 45 minutes can also help you stay healthy!
- Say NO to smoking: While harmful to your lungs, smoking can also harm your eyes. Regular smoking increases your risk of age-related eye diseases such as cataracts and macular degeneration. These diseases result in affecting the optic nerve of the eyes.
- Maintain a healthy body: An unhealthy lifestyle affects your overall health, including your eyes. Therefore, it is crucial to maintain a healthy lifestyle by maintaining a healthy body weight, consuming proper nutrition, and incorporating regular physical exercise.
- Take care of your eyes: Preventive practices can help in maintaining your eye health. Here are some tips for you to take care of your eyes:
- Eye protection: Use proper eye protection such as safety glasses and goggles when doing certain activities like playing sports, swimming, construction work, or home repairs. There are high chances of something falling into your eyes during these activities and affecting them adversely.
- Wear sunglasses: UV-A and UV-B sun radiations harm your skin and eyes. Safeguard your eyes from harmful rays by wearing sunglasses when out in the sun and on cloudy days.
- Give your eyes a break: Monitoring screen time also helps limit the stress our eyes are exposed to. Try to practice the 20-20-20 rule. Look away from the screen, about 20 feet before you, for 20 seconds every 20 minutes. It will prevent eye fatigue, headaches, and migraines.
- Take precautions if you wear contact lenses: Make sure your hands are clean before wearing contact lenses. Always wash your hands thoroughly, even when you have to extract an eyelash or if you have the urge to rub it slightly.
- Know about family history: Some eye diseases are inherited, making it imperative for you to be aware of any eye conditions running in your family. Awareness always helps mitigate the risk of eye diseases or infections influenced by family history.
- Know about age-related disorders: Aging increases the risk of developing several age-related eye disorders and conditions. Therefore, it is crucial to know your risk factors to lower the risk through preventative practices.
How does a routine eye exam boost your health?
During a routine eye exam, ophthalmologists analyze the patient's risks for a specific disease based on family medical history, age, and race. They may conduct health screenings and diagnostic tests for a proper disease diagnosis.
Most eye conditions are called silent ailments, as they do not usually show symptoms. In most cases, the patient may be partially vision impaired when the symptoms first get noticed. For instance, glaucoma, ocular melanoma, or age-related macular degeneration are potentially blinding eye diseases that do not show any early signs until they become severe and impair vision. Ophthalmologists can identify these eye diseases early and provide effective treatment. It helps cure the disease and prevents it from becoming a major health complication.
Ophthalmologists also guide patients on healthy lifestyles and eating habits to protect their vision and ensure the longevity of the treatment results. They suggest safeguarding the eyes from direct ultraviolet light exposure to avoid worsening the eye condition. Some dietary supplements may be detrimental to eye health. Ophthalmologists can also guide you on which supplements to avoid or add to your diet, depending on your ailment.
When should you see an eye doctor?
- Sudden vision loss should never be ignored, even if you experience vision darkness or blackout for a few seconds. It could be a sign of potentially blinding eye disease. Ophthalmologists are trained to detect these conditions and offer necessary treatment to prevent vision loss.
- Eye infections can lead to severe complications and even blindness if untreated. If you experience an eye infection, do not ignore its symptoms; see the eye doctor immediately.
- Sudden blurriness and vision change could indicate underlying eye ailments like age-related macular degeneration, cataracts, and systemic or retina disease. See the eye doctor immediately if you notice such symptoms.
- Acute eye injury can be severe as the eye is a delicate organ. If you experience an eye injury, you must see a qualified ophthalmologist. Emergency departments can provide the first line of medical care and even help restore eye vision.
- Double vision can be caused due to nerve injury or systemic brain conditions. You must pay attention to the issue and see the eye doctor at the earliest.
- Flashes or floaters in your eyesight could be a symptom of an underlying disease like retina detachment. Seeing the ophthalmologist helps understand the condition and receive treatment.
What is digital eye strain? How can you relieve or prevent it?
Spending long hours on a computer screen or other digital devices can cause eye or vision-related symptoms, leading to eye strain or fatigue. This is known as computer vision syndrome or CVS. CVS can affect people of all ages and cause headaches, blurry vision, eye pain, tearing, tiredness, or a burning sensation. These may be caused by poor lighting, poor seating posture, glare on a digital screen, or a combination of all these problems.
If you experience constant eye strain, you may want to consult an eye doctor near you who can find out the underlying cause of your eye problem.
Incorporating a few simple practices in your routine can help alleviate digital eye strain:
- Switch to computer glasses: Prescription computer glasses are designed to meet the visual demands of screen use and enhance visual comfort. These are not the same as blue-light-blocking glasses. Computer glasses may include multifocal lenses, which help shift focus between near and distant objects.
- Blink often: Humans naturally blink about 15 times per minute, but this can drop to 5–7 times per minute when using digital devices. Frequent blinking keeps the eyes lubricated, preventing dryness and discomfort.
- Follow the 20-20-20 rule: To reduce strain, look at any object that is placed 20 feet away for a minimum of 20 seconds at every 20 minutes. This practice allows your eyes to fully relax.
- Adjust your device's brightness, font size, and contrast: When your phone or computer screen glows brighter than your natural surroundings, your eyes may have to work harder to read or see things on the screen, which often leads to strain. You can use a matte screen to reduce the glare. Increasing the font size to view text on your screen can prevent squinting, thereby reducing your eye strain.
- Use lubricating eye drops or artificial tears: Lubricating eye drops can relieve dryness by replenishing the tear film and protecting the surface of the eyes. These drops are available over the counter and can be used as needed or as directed by an eye doctor.
