As a conscious society, we don't see it much anymore, but it is still a health-threatening situation, eyeglasses sold on the streets.
These are products that are harmful to health, which are sometimes sold as sunglasses and sometimes as close glasses. Although it attracts attention at first glance because it is nice and cheap, it actually poses great threats.
Even though ophthalmologists and optical centers are warned about this issue, big problems will be faced if attention is not given as a society.
The most important thing in glasses used for our eye health is the quality of the glasses. Its transparency, homogeneity and neutrality are very important. In the selection of sunglasses, the glass numbers should be 0 and they should be the same naturalness on the whole surface. Any surface problem on the glass can have negative effects on vision. Especially in childhood, eye disorders and problems may occur due to poor quality sunglasses used.
Another important issue is the issue of close glasses. This issue is of particular importance. Because the number of each person's two eyes is not always the same. It can contain not only spherical value but also cylindrical value. And because of the PD values that are different in each person, the glass foci change. However, glasses sold on the streets do not have such features. We have already explained that the quality of the glass may be deteriorated. In addition, the number of glasses that every person can use should be determined by ophthalmologists. Our patients try to determine this number by trying it on peddlers. As a result, there may be high numbers of usage in general and this causes premature deterioration in the eye muscles.
For these reasons, I would like to warn you that it is absolutely necessary to buy glasses from optical opticians, whether it is sunglasses or near-distant optical glasses, in order to protect eye health.
