Standard monofocal lenses provide clear vision at one distance (typically far), requiring glasses for other distances. Premium lenses include options like multifocal, EDOF (Extended Depth of Focus), and toric lenses that can correct astigmatism and provide clear vision at multiple distances, potentially eliminating or reducing dependence on glasses.

For most adults, a comprehensive eye exam including glaucoma screening is recommended every 1-2 years. However, those with risk factors (family history, diabetes, high myopia, or over age 60) may need more frequent monitoring. Early detection is crucial since glaucoma often has no symptoms until significant damage has occurred.

Watch for signs like squinting, head tilting, frequent eye rubbing, sitting too close to screens, poor concentration, declining school performance, or visible eye misalignment (crossed eyes). All children should have their first comprehensive eye exam by age 3-5, even without symptoms, as many vision problems can be corrected if caught early.
