Myopia causes you to see distant objects very blurry, this problem can be solved with corrective glasses. Also, with contact lenses or surgery that completely eliminates this problem, so you will not have to resort to glasses.
In farsightedness, near objects are not seen clearly, while distant objects are seen clearly. This disorder can be mild or severe and each is based on the ability to see at a distance or up close.
If you suffer from astigmatism, you will most likely see images blurred and with some clarity in their contours. On the positive side, it can be corrected with prescription eyeglasses, intraocular lenses or laser surgery.
After the age of 40, this condition becomes present and is related to aging. Presbyopia makes near objects blurry and you will notice it when reading, so you will need prescription glasses.
The use of corrective glasses is a problem that many people in the world suffer from. Therefore, it is necessary to know what type of glasses you need according to your vision problem and we detail them below:
This refractive problem requires further evaluation, especially if it is accompanied by myopia and hyperopia. That is why it is solved with a toric or cylindrical lens and you must wear prescription glasses for most of the day.
Glasses to correct myopia should be of the concave type and are characterized by being thicker in the area of the edges. In addition, the center is thinner, this makes the eyes of the person wearing these prescription glasses look smaller.
The lenses that solve this problem are convergent lenses, since they improve the focusing of light. The lenses for hyperopia vary according to their thickness and are related to the graduation levels or diopters.
If you are tested and you have 2 diopters, we recommend that you buy custom-made glasses, because they fit perfectly and are small. Also, in graduations ranging from medium to higher, it is better to choose quality prescription glasses, so you will not feel discomfort due to the weight of the glass.
Can’t see like you used to and have been diagnosed with presbyopia? Bifocal glasses will become an excellent option to see as before. Also, monofocal and progressive or multifocal glasses, each will depend on your vision loss.
