yksittäislasit

Yksittäislasit, known in English as single vision lenses, are a type of eyeglass lens designed to correct vision at a single distance. This means they are crafted to provide clear sight for either near vision, far vision, or an intermediate distance. Unlike multifocal lenses such as bifocals or progressive lenses, which have different optical powers in different parts of the lens to correct for multiple distances, single vision lenses have a uniform prescription throughout.

These lenses are commonly prescribed to individuals experiencing myopia (nearsightedness), hyperopia (farsightedness), or astigmatism. For example, a person who can see clearly up close but has difficulty seeing distant objects would receive single vision lenses for distance correction. Conversely, someone who struggles with reading or close-up tasks would be fitted with single vision lenses specifically for near vision.

The manufacturing process for yksittäislasit is relatively straightforward, involving the grinding of a specific curvature onto the lens surface to achieve the desired refractive power. They are a widely used and effective solution for common refractive errors. Patients typically find them easy to adapt to due to their consistent visual correction across the entire lens surface. The simplicity and effectiveness of single vision lenses make them a popular choice for many eyeglass wearers.
