How to Improve Your Eye Health & Offset Vision Loss | Dr. Jeffrey Goldberg

Every newborn should have a basic eye exam in the nursery, primarily to confirm a normal red reflex (the same red-eye effect in flash photos). An absent or white reflex can signal serious problems like retinoblastoma. Through early childhood, parents should watch for lack of eye contact, failure to track sounds/objects, or rapid flickering eye movements (nystagmus), all of which warrant an eye exam. In early elementary years, school screenings often catch amblyopia (lazy eye) due to unequal prescriptions or misaligned eyes (strabismus), which must be treated early to avoid permanent vision loss.

Older thinking blamed near work (reading, screens) alone for myopia, but newer cohort studies and randomized trials suggest time outdoors in full-spectrum daylight is a stronger protective factor. Kids who spend at least 1–2 hours a day outside tend to show slower progression of nearsightedness. The exact dose–response and optimal duration (e.g., 1 vs. 3 hours) still need rigorous trials, but combining outdoor time, mixed near/far viewing, and limiting continuous near work appears beneficial.

Silent diseases like glaucoma can progress for years without symptoms, especially because they initially damage peripheral vision and elevated eye pressure cannot be felt. In your teens–30s, a single baseline comprehensive exam may suffice if asymptomatic. After ~40, presbyopia and increased risk of glaucoma and macular degeneration make regular exams more important. A real exam includes pressure measurement, dilated or imaging-based evaluation of the retina and optic nerve, and alignment/refraction checks, whether done by an optometrist or ophthalmologist.

For presbyopia and distance prescriptions, Goldberg emphasizes that wearing appropriate correction does not meaningfully accelerate dependence. Under-correcting to “exercise” your focusing muscles may slightly affect progression, but it deprives the retina and brain of sharp input, which is more important for function and learning. For alignment problems (strabismus), however, clinicians often intentionally under-correct prisms or use exercises to train the extraocular muscles rather than fully compensating with lenses.

Contact lenses often provide sharper, higher-quality correction than glasses because they sit directly on the cornea and can smooth higher-order aberrations. But they reduce oxygen and alter tear dynamics on the corneal surface. Goldberg strongly favors daily disposables over 2–4 week lenses to reduce infection risk and discourages sleeping in contacts due to hypoxia and bacterial/fungal infection risk. As people age and tear quantity/quality decline, many will need to reduce wear time or reserve contacts for limited use.
