Sunglasses

After arranging the appointment in advance, we perform an optical refraction test. Our specialist interviews the patient regarding previous correction (if any), last ophthalmic / optometric visit, eye disease or medication. At the beginning we take a photo of the fundus with a scanner. Then the pressure is measured using the non-contact method using an air tonometer. air-puff, this measurement requires no anesthesia and is painless, it relies on a quick and gentle air blast towards the cornea. The next step is to perform a computer eye test on a device called an autorefractometer. Looking at this device first one then the other eye we see the image usually it is a balloon at the end of the road. At first, the image is blurred until it becomes sharp after a while. During this time, your collection ability is measured using infrared rays. This test takes several seconds. The result obtained specifies the first information regarding the ability to see. After these measurements, we move to the most important examination called „subjective eye examination”. This test is carried out on a device called the optopter. There are various types of questions asked by the optometrist, whose purpose is to determine the visual acuity of the distance to the distance. This test lasts the longest of all, usually about 20 minutes. After this time, the correction is already known, the test results are discussed with the patient and the prescription for the glasses is recorded. An optometrist may also suggest specific lenses that will be ideal for the patient….

Photochromic lenses

Simply put, photochromic lenses darken when exposed to UV radiation. As a result of this process, the user of these lenses receives eye protection. When in the sun, the lenses will stain, e.g. dark gray, while when we are in the room, e.g. the store, the lenses will discolor. It is also worth remembering that the basic models of photochromic lenses do not work in the car. There is a photochromic lens on the market that works in a car. It uses a lower wavelength of visible light so that it does not need UV light for darkening.

We associate photochromic lenses with older people, usually we associate them with brown or gray tinting. Times have changed and technology has also changed. Nowadays, we have the opportunity to choose many variants in terms of color and ending with anti-reflective coating. Thanks to this, we can get an original and elegant effect that will certainly not be associated with the 90s.
