How do I take care of my glasses?

Few tips to extend the life of your spectacles:

1.Always take them off using both hands

2. Store them in a case and never place them with the glass down to prevent abrasion.

3. Do not expose them to temperatures higher than 40° C (car, sauna, hair dryer, heating sources, grill).

4. Clean them with warm water and a neutral dish cleaner. Rinse them with running water.

5. Don’t expose the glasses to solvents and other agressive substances.

6. When on the way, clean the lenses with microfibre cloth and cleaning spray. Make sure the cloth is kept clean, best by always storing it in enclosed case.

7. The microfibre cloth is washable up to 40° C. The rubber parts on one side ensure better grip for optimum cleaning.

 

 

How to get used to progressive lenses??

Progressive lenses have three zones of vision – distance, intermediate and near. They provide sharp vision at all distances. It is fairly simple to learn how to use them.

different zones of progressive lense

No matter what you are looking at, always turn your head towards the object, then raise or lower your head to focus the image. This way, you will always use the part of the glass that is intended for specific distance.

Looking up and down through the glass allows you to smoothly and continuously change the distance of sharp vision.

Simple exercise:
– look straight out the window (this is your far vision)
– slowly look closer to you, e.g. on the table (this is the intermediate vision)
– by using lower area of the lense look at a script on a paper sheet you are holding (this beeing your near vision)

Now change the view from a distance to near and back – the glasses allow continuous viewing at all distances.

The sharpness of the image changes as you raise and lower your head – you can use the following technique to finetune your focus while performing various visual tasks:
Look at your feet while standing straight and not moving your head down. Now lower your head until your image of legs is sharpened. This exercise will help you walk the stairs.

Now let’s explore the peripheral vision. Look straight ahead and move your eye view away from the center of the lens to the side. The side part of the lense is not intended for sharp, but it helps your orientation. Use the central parts of the lense for sharp vision by turning your head towards objects you observe.

It is important to adjust the spectacles in such a way that the position of the lenses will be close to our eyes. If they slip down the nose, the lenses will be positioned to far away and consequently the fields of vision will narrow.

If it happens regularly, it is recommended that you visit your optician to readjust the spectacles..

I have problems with tired eyes when working with a computer. Is there a solution?

Computer screens, tablets, telephones and televisions, as well as artificial lighting, emit harmful blue-violet light. This light causes fatigue and pain in the eyes, but it can be effectively eliminated with BlueViolet Blocker lenses.

Cheaper sunglasses are also on the market. Why buy more expensive glasses from an optician?

In the production of cheaper sunglasses, the cost of production is an important criterion in the production of these. Many times, cheap foil is used for the lenses of such glasses, but not high-quality optical glass. Such a film does not have a stable diopter over the entire surface and can have distortions that cause vision problems – eye pain, headache, blurred vision,… Also questionable is the durability of UV protection, which can be reduced after a while and the glass lets harmful UV light through.
Quality glasses from renowned manufacturers have surface protection against wear, stable surface, solid frame, anti-reflective coating, permanent and complete UV protection, …

Can I use “ready-made glasses”?

Mass-produced glasses are available for immediate use, they are available in pharmacies, post offices, gas stations, drugstores… They are intended for short-term use (up to 10 minutes) or as a backup if your prescription glasses get damaged.
The disadvantage of such glasses is that they are made in advance and not according to individual user data.
In the case of glasses that you get in optics, your interpupillary distance, differences in the diopters of the right and left eyes, astigmatism and other parameters are taken into account during the production.

Due to inappropriate parameters, prolonged use of ready-made glasses can cause visual impairment and headaches.
Even if the diopter of the glasses is approximately appropriate, there is a high probability that the distance of the optical centers of the glasses is not identical to your interpupillary distance. Even a small deviation between the distances causes the prismatic action of the glasses, which can cause squinting (strabismus).
Finished glasses are always shaken by built-in spherical lenses that do not correct astigmatism, your eyes have not been examined by an ophthalmologist, often the lenses are cast from non-optical materials. The glasses do not have anti-reflective coatings for greater visual acuity and hydrophobic coatings for easier cleaning.

What are the advantages of anti-reflective lenses?

The anti-reflective coating greatly reduces the disturbing reflections of light from the glass surfaces. The picture we see is much clearer and clearer, the eyes get less tired, which is especially important when we do precise work, while driving, while studying,…
At Alcom, antireflection is always combined with a hard coat for longer glass life and a hydrophobic coating to make it easier to clean the lenses and reduce dew. The combination of these coatings is called Opal.

What are photosensitive lenses?

Photosensitive lenses are made of special materials that darken in sunlight and brighten in the room and at night. Regardless of the darkening, they completely block UV rays. Anti-reflective layers can also be applied to these lenses for better vision quality, because with dark glasses, reflected light is more disturbing.

After 45, I need different glasses to look at near than to look at a distance. Are there glasses that would combine both diopters?

The solution is the progressive Magic lenses, which allow viewing at all distances – from near, through medium distances to distance. Magic progressive lenses for the smallest frames and Magic Sport for curved sports and solar frames are also available.

Because I have a higher diopter, I wear glasses with heavy and thick lenses. What lenses should I choose in the future?

The weight and thickness of the lenses depend on the diopter, the material and type of lenses and the size of the frame. Therefore, it is advisable to choose lenses that are made of light organic materials, at higher diopters they should be aspherical and thinned. Don’t worry about the fact that organic (plastic) materials are softer because they are protected by a hard coating that makes them harder and more resistant to wear. Also choose a smaller frame – the lenses will be significantly thinner and lighter than with a larger frame.

Should I opt for mineral or organic glass?

Nowadays, the difference between mineral and organic lenses is mainly only in weight – organic glasses are half as light, and they are much harder to break, so they are safer. Organic lenses are mostly supplied with a hard coating, so they are not as susceptible to mechanical damage – when used properly, they are just as durable as mineral lenses. Optically, they are just as high quality as mineral lenses. Mineral lenses in refractive indices 1.80 and 1.90 are slightly thinner than thinned organic lenses, but much heavier.
