korjauslasit

Korjauslasit, often referred to as prescription glasses, are optical devices designed to correct vision impairments. They work by bending light rays to focus them properly on the retina, the light-sensitive tissue at the back of the eye. This precise bending of light compensates for refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism (an irregularly shaped cornea), and presbyopia (age-related difficulty with close-up vision).

The lenses in korjauslasit are custom-made based on an individual's eye examination results, known as a prescription. This prescription specifies the type and strength of lens needed for each eye. Common lens materials include glass, polycarbonate, and high-index plastics, each offering different benefits in terms of durability, weight, and thickness. Lens coatings can also be applied to enhance performance, providing features like anti-glare, scratch resistance, UV protection, and blue light filtering.

The frames of korjauslasit are chosen for comfort, fit, and aesthetic preference, and they hold the lenses in front of the eyes. Regular eye check-ups are recommended to ensure the prescription remains accurate, as vision can change over time. Korjauslasit are a widely used and effective tool for improving visual acuity and quality of life for millions of people worldwide.
