Why We Ask These Questions – Patient Education.

Welcome! This page explains the medical and vision-related importance behind the questions on your health questionnaire.

👁️​Vision, Lifestyle & Eye Health

• When was your last eye exam?
  Regular eye exams help detect early signs of vision problems and eye diseases—even when you haven’t noticed symptoms. For example, someone who hasn’t had an exam in over a year might not realize their blurry driving vision is due to a prescription change or early cataracts.
• Do you currently wear glasses or contact lenses?
  This lets us understand how you manage your vision day-to-day. For example, if you wear over-the-counter readers but complain of blurry distance vision, it may be time for a full prescription.
• Would you like to try contact lenses and schedule a fitting today?
  We ask this to explore your interest in contact lenses as a convenience or cosmetic option. For instance, someone who wears glasses but plays sports or attends social events may benefit from contacts as a backup or primary vision correction method.

💻Screen Use & Driving

• How many hours per day do you use digital screens?
  Extended screen use can cause digital eye strain, dryness, and blurred vision. For example, someone working on a computer for 6–8 hours daily may experience tired eyes or frequent blinking without realizing it's connected to screen time.
  
• Do you primarily use screens for work or school?
  Knowing the reason for screen use helps tailor our recommendations. For example, students using tablets or professionals on dual monitors may benefit from blue light filters or specific lens coatings to reduce fatigue.
  
• Has your night vision changed recently?
  Sudden or progressive trouble seeing at night can indicate cataracts, retinal issues, or prescription changes. For example, if headlights seem extra bright or you notice halos while driving, it might point to a condition needing evaluation.
  

⚠️​Vision Symptoms 

• Blurred Vision
  Can indicate uncorrected refractive errors (nearsightedness, farsightedness), or more serious issues like cataracts or diabetic changes. For instance, a patient who struggles to see signs while driving may just need updated glasses—or may have early lens clouding.
  
• Dry Eyes
  Common in patients who work on screens, wear contact lenses, or live in dry environments. Someone who constantly uses artificial tears or rubs their eyes may be experiencing chronic dryness that needs treatment.
  
• Night Vision Problems
  Often related to cataracts, retinal health, or high prescriptions. A person who avoids night driving may be struggling with glare, halos, or depth perception changes.
  
• Headaches
  Can stem from uncorrected vision problems, digital eye strain, or focusing difficulties. For example, tension headaches after using a computer may be relieved by proper prescription lenses or adjusting ergonomics.
  
• Eye Strain
  Frequently seen in students, office workers, or anyone focusing at near distances too long. Symptoms include tired, heavy eyes or needing to close eyes to “reset.”
  
• Light Sensitivity
  May be caused by dry eyes, inflammation, or photophobia from conditions like migraines. Someone squinting indoors or always wearing sunglasses might benefit from medical evaluation.
  
• Flashes or Floaters
  Important to monitor—new floaters or flashing lights can signal a retinal tear or detachment. A patient who sees “spiderwebs” or sparkles should be examined urgently.
  
• Frequent Eye Infections
  Recurring styes, conjunctivitis, or red eyes could be signs of poor lid hygiene, contact lens issues, or chronic blepharitis. Identifying these early helps prevent long-term damage.
  

👁️Medical History – Eye Conditions 

• Cataracts
  Clouding of the eye’s natural lens. Patients often notice blurred vision, trouble with glare at night, or faded colors. It’s a common age-related condition that may eventually require surgery.
  
• Glaucoma
  A condition that damages the optic nerve, often without noticeable symptoms until significant vision is lost. Family history or elevated eye pressure increases risk. Patients may lose peripheral vision without realizing it.
  
• Macular Degeneration (Degeneración Macular)
  A disease affecting central vision, critical for reading and recognizing faces. Someone who says, “I can see around things but not directly at them,” may be showing early signs.
  
• Keratoconus
  A progressive thinning of the cornea that causes visual distortion. Common symptoms include double vision in one eye, ghosting, and frequent prescription changes.
  
• Retinal Detachment
  A medical emergency where the retina separates from the back of the eye. Sudden flashes, floaters, or a shadow in peripheral vision may be signs. Early treatment is critical to prevent permanent vision loss.
  
• Diabetic Retinopathy
  Caused by diabetes damaging the retina’s blood vessels. Patients may not notice early symptoms but could develop blurry vision, floaters, or vision loss without proper diabetes control.
  
• Dry Eye Syndrome
  A condition where the eyes don’t produce enough tears or the tears evaporate too quickly. This causes discomfort, burning, and blurred vision—especially in screen users or contact lens wearers.
  
• Amblyopia (Lazy Eye)
  Reduced vision in one eye from poor development in childhood. It’s important to know if a patient had this, especially for depth perception or visual acuity differences between eyes.
  
• Other
  This lets patients list uncommon or unique diagnoses like ocular tumors, past eye surgeries, or rare inherited conditions that may impact current care.
  

🩺​General Health Conditions 

ENDOCRINE & CARDIOVASCULAR Questions:

• Have you been diagnosed with diabetes (Type 1, Type 2, or Gestational)? Important for identifying patients at risk for diabetic retinopathy — damage to the retina from high blood sugar. Tracking A1C levels helps monitor systemic control. Example: A patient with high A1C is more likely to develop retinal bleeding.
• Do you have pre-diabetes? Pre-diabetes can still cause early retinal changes. Early intervention helps reduce long-term eye risks. Example: Even without a diabetes diagnosis, blurred vision may be related to glucose fluctuations.
• Do you have a thyroid disorder? Thyroid conditions can cause dry eye, double vision, or eye bulging due to inflammation or muscle involvement. Example: Graves’ disease may lead to swollen eyelids or difficulty closing the eyes completely.
• Do you have high blood pressure? Hypertension can lead to hypertensive retinopathy — a condition where retinal blood vessels are damaged. Example: Uncontrolled pressure may cause vision-threatening retinal bleeding.
• Have you been diagnosed with heart disease or had a stroke? These can affect blood flow to the eyes or brain. Strokes can cause permanent vision loss or field defects. Example: A person with a history of stroke may experience difficulty with side vision.​

NEUROLOGICAL & AUTOIMMUNE Questions:

• Do you suffer from migraines or headaches? These may be linked to eye strain or visual disturbances such as flashing lights or tunnel vision. Example: Ocular migraines can mimic retinal symptoms, needing accurate diagnosis.
• Have you had seizures or epilepsy? Seizure activity or medications may affect visual fields or clarity. Example: Some seizure medications can cause double vision or dry eye.
• Do you have autoimmune conditions such as lupus, rheumatoid arthritis, HIV/AIDS, or shingles? These conditions often lead to inflammation inside the eye or complications from medications. Example: Lupus may cause uveitis; Plaquenil use requires regular eye monitoring.
• Other autoimmune disease? Allows detection of rare conditions affecting ocular structures. Example: Sarcoidosis or MS can present with optic nerve swelling or visual symptoms.

RESPIRATORY & HEMATOLOGIC Questions:

• Do you have asthma, chronic bronchitis, or tuberculosis? Respiratory conditions may influence oxygen flow to the eye. Inhaled or systemic steroids may elevate eye pressure. Example: Asthma patients using steroids may develop steroid-induced glaucoma.
• Do you have anemia or blood clotting disorders? Anemia affects retinal oxygenation, and clotting issues may increase the risk of retinal hemorrhages. Example: A patient with anemia may report fatigue and blurry vision.
• Other health conditions? Gives patients space to mention conditions we might not have covered. Example: A rare genetic condition may require referral or special testing.​

🧬​​Family Medical History

• Do you have a family history of blindness or glaucoma? These can be inherited and may require more frequent eye exams. Example: A patient with a parent who had glaucoma is at higher risk and may need annual pressure checks.
• Is there a family history of diabetes or high blood pressure? These systemic conditions increase the chance of developing diabetic or hypertensive retinopathy. Example: A sibling with diabetes can suggest shared genetic risks, guiding earlier screenings.
• Have family members had cataracts or macular degeneration? Both have hereditary components that can prompt earlier evaluations. Example: If a patient’s mother had macular degeneration, we may start early retina imaging.
• Other family medical history? Open field allows inclusion of genetic disorders or rare diseases that impact the eyes. Example: Retinitis pigmentosa or Marfan syndrome might not be listed but are important to know.​​

🎨​Color Vision Screening

• Have you ever had a color vision test before?
  Establishes a baseline and reveals whether the patient has ever been evaluated for color deficiency.
  Example: Someone unsure may benefit from a screening to uncover undiagnosed deficiencies.
  
• Do you have trouble telling certain colors apart (like red/green)?
  Screens for congenital or acquired color deficiencies, important for occupational and safety reasons.
  Example: A school-aged child struggling with red and green may misinterpret classroom visuals.
  
• Have you noticed recent changes in how you see colors?
  Color perception changes can signal optic nerve or retinal issues.
  Example: A patient with optic neuritis may suddenly see washed-out or dull colors.
  
• If yes, when did it start?
  Provides timeline for changes, helping differentiate between acute vs. chronic issues.
  Example: Sudden color change may need urgent evaluation for inflammation or swelling.
