It is impossible to give universal advice on choosing the perfect frames and lenses. But there is one golden rule: when choosing frames you should consider not only their appearance but also discuss the following questions with a specialist (optometrist): Where and how, mostly, are you going to use your glasses? What are your habits? Do you plan to wear your glasses while playing sports, for example? Eyeglass lenses have different optical powers, which are expressed in dioptres. The optical power is determined by fitting glasses. Size of the frame - the larger the frame the more aberration (distortion) may be at the edges of the lens.
What frame fits on the lens?
Metal and plastic frames are equally suitable. In particular, active activities such as riding a motorcycle, running or playing ball require curved frames to protect the eyes from wind, insects, debris, etc.
How do you know if eyeglass lenses aren't right?
You can tell if lenses are not suitable by certain signs. It is important to understand that there is an adjustment period for any optics. Symptoms of improperly fitting glasses are as follows: headache; dizziness; a feeling of sand, increased tearfulness of the eyes; high fatigue of the organs of vision.
Why do my eyes hurt when wearing new glasses?
Eye muscles learn to compensate for changing visual demands. Because these muscles and focusing systems suddenly have to work differently, you may develop headaches, dizziness, or just a feeling that something is wrong with your eyes. (This also applies to contact lenses).
Which glass or plastic eyeglass lenses are better?
Glass makes it difficult to make a progressive or aspherical lens. Also, glass lenses do not fit rimless frames. Plastic lenses are twice as light as glass lenses, so glasses with them are more comfortable to wear for a long time, and plastic lenses are much less traumatic than glass lenses. Firstly, plastic itself is more resistant to breakage, and secondly, its splinters are not as sharp and dangerous.
Which lenses for glasses are more expensive?
The thinner and stronger the lenses, the more expensive they are. Lenses made of photochromic, polarizing or sunglasses are more expensive than colorless (clear) lenses. Lenses can be stock or prescription lenses. Stock lenses are cheaper - they are ready-made, in stock, and can be quickly fitted to eyeglasses.
