Selecting glasses components

Depending on the habits, lifestyle and the received recipe, the components of the glasses are selected. Properly selected models give maximum visual acuity or complete correction. According to indications, for example, with astigmatism, an ophthalmologist may prescribe an incomplete correction.

Lenses

The lenses of eyeglasses designed to restore visual acuity have a refractive power. Optical power is measured in diopters and indicated in the prescription in accordance with the diagnosis. Lenses are classified:

• according to the materials of manufacture. There are polymer, polycarbonate, mineral glass. Glass lenses are superior to plastic lenses in many ways;
• by type: monofocal, progressive, multifocal;
• by thickness: standard, thin, ultra thin;
• by type of coating: anti-reflective, anti-shock, photochromic, anti-faux blue, mirror.

Models with anti-reflective coating, anti-blue tone are suitable for working at a computer, driving a car, fishing. Photochromic “chameleons” provide eye protection from ultraviolet rays. The mirror coating makes the product opaque from the outside. For people working in difficult conditions, dirt-repellent compounds are applied to the lenses.

All of the listed lens parameters affect the quality of vision, so you need to add or remove options with professional advice and taking into account habits and lifestyle.

The second important component is the frame, which determines the aesthetic component.

If there are contraindications or deviations from the indicated norms, you should pay attention to corrective glasses or contact lenses.

General recommendations for scoring

Points can be ready, ie. mass-produced according to standard parameters. Models are suitable for people whose vision deficiency is expressed in round diopter values and who are not going to use the accessory often.

When choosing a model, it is important to take into account not only prescription data. Matter:

• manufacturer of frames and lenses. Korean, Israeli, German, Japanese products are considered the best;
• lens material. Plastic is lighter, glass is more scratch resistant;
