The world is enormous and… problems are lurking all over. Indeed as part of life vision problems are lurking all around. Our vision is most valuable as good vision is health and helps us for higher quality of life. Our eyes, as vison sensory organ, have an extremely complex structure and a delicate, easily exposed nature. Due to their fragility, unfortunately, our eyes could be affected by numerous diseases from infancy to late old age.
What is the most common cause of impaired vision and blindness?
It is interesting, and certainly useful, to know what is worldwide the most common cause of impaired vision and blindness. Based on a systematic review of medical studies in different countries and continents, we can sum up information about the leading illness amid the most common causes of blindness or severe visual impairment worldwide. The top five causes in our region, i.e. Central and Eastern Europe, include:
- Cataract – the clouding in the eye lens is one of the most common causes of vision impairment, responsible for about 16 million people affected worldwide.
- Age-related macular degeneration – the damage to the retina central part counts among main causes for severe and irreversible vision loss in developed countries.
- Glaucoma – a common eye condition where the optic nerve connecting the eye with the brain is damaged. It develops slowly over many years and affects peripheral vision first.
- Existing refractive error – need for diopters that could have been corrected with glasses, but was not. Nearsightedness, farsightedness, astigmatism, and presbyopia are the four most common refractive errors.
- Diabetic retinopathy – a complication of diabetes affecting the eyes. It is caused by damage to the blood vessels in the light-sensitive tissue at the back of the eye (the retina).
The salvation solution – prevention and treatment!
Therefore, the five most common ‘lurking’ vision problems for our eyes are identified. However, for each problem, a solution is lurking, or as the title of a Bulgarian movie says: ‘…salvation is lurking all around!’
Indeed, salvation is in prevention, salvation is in treatment. So, the Kosevi Optics, Varna Optics, and the Eye Clinic Dr. Kosev team’s mission is to offer solutions and relief from the most common and sight-threatening eye diseases.
The key advice by professionals is: preventive ophthalmologic examinations are of primary importance for keeping eyes healthy and having perfect vision. Exams frequency depends on the patient’s specific condition – be it every six months, once per year, or every three years – the interval between preventive exams at an ophthalmologist is strictly individual.
If treatment is needed, the team of specialists at the Eye Clinic Dr. Kosev provides solutions for salvation:

Her personal mission is part of the team’s general mission – prevention of diabetes-related eyes damages.
Farsightedness, nearsightedness, astigmatism…
Now, let’s talk about perhaps the most surprising for most of us frequent cause of visual impairment in Europe, and worldwide – existing refractive anomalies. In other words, these are our trivial and associated with most of us farsightedness, nearsightedness, astigmatism, and presbyopia. Yes, they affect a large percentage of the worldwide population being the leading cause of vision impairment and a secondary cause of blindness! If non-corrected the refractive deviations can radically reduce a patient’s education opportunities, work capacity, and overall quality of life. Kosevi Optics, Varna Optics, in cooperation with the Eye Clinic Dr. Kosev, help patients solve these problems for years. In addition, patients can find solution to problems such as dry eyes or the necessity for computer protection glasses.
Founded in 1999, Optics offer to present days ‘salvation’ to their patients with professionalism, involvement and innovative solutions. Every patient seeking assistance gets a prescription for glasses, signed by a specialist ophthalmologist or optometrist.
Optometry is not a very well-known specialty in Bulgaria. Optometrists are medical professionals who focus on refraction and vision correction through various methods. The specialists teams at Kosevi Optics and Varna Optics includes also an optometrist – Ralin Kosev. He graduated with honors in Medical Optics from the Medical College – Varna within the Medical University Prof. Dr. Paraskev Stoyanov – Varna. He has internships in eye optics in France and Milan, Italy. He studies optometry at Medical University – Varna Prof. Dr. Paraskev Stoyanov, Faculty of Public Health.
In addition to the prescription of diopters by an ophthalmologist or optometrist, Kosevi Optics and Varna Optics offer their own brand of highest quality dioptric lenses for glasses ‘Quality Expert,’ manufactured in the European Union. Of course, the opticians team perfectly understands the needs and desires of contemporary men for modern vision.

And something more! In present days online shopping is a new kind of salvation. Striving to facilitate their patients in every way, Kosevi Optics and Varna Optics shaped an online POS at the address: https://varnaoptics.com/ . The Internet POS provides options for ordering selection of glasses online, once the patient attaches a prescription from an ophthalmologist. The process is simplified to max and includes a careful analysis of the online order made by the patient by an optician-specialist, as well as an individual consultation by phone if necessary.
