How To Pick The Right Reading Glasses
Unfortunately, most people who have crossed the 40-year mark begin to notice that they can only read various texts by stretching their arms out to their full length. Over time, the length of the arms ceases to be enough for the normal perception of the text.
If you are already thinking about how to choose reading glasses, then it's time to learn a little more about it. How to understand that you need them and whether it is possible to protect your eyes from the effects of the monitor in such glasses - we will tell you in more detail.
How To Choose The Right Reading Glasses
In the process of choosing lenses for reading, the doctor will use a special table with texts of different sizes. The smallest is distinguishable for people with vision equal to 1.0. The largest, located at the bottom, corresponds to a vision of 0.1.
The table is placed at a distance of 33-35 cm, but if necessary, use glasses for reading and when working on a laptop, you should place the table further, thereby simulating a real situation.
Ratio age / lens parameters:
- at 40 you will need +1.0 D lenses;
- at 45 - already +1.5 D;
- by the age of 50 - +2.0 D;
- upon reaching 55 years old - +2.5 D;
- at 60 years old - +3.0 D;
- at the age of 65, the strength of the lenses increases to +3.5 D.
The above norms are averaged and do not take into account the peculiarities of vision: the presence of astigmatism, the uniformity of refraction of the eyes, the distance between the centers of the pupils, etc.
Thus, it is best to change glasses every 5 years. After overcoming this milestone, the development of presbyopia stops, since the crystalline lens loses its elasticity.
Choose a perfect quality and beautiful frame, do not forget about a durable case. It should be understood that such types of accessories also need care, as well as ordinary glasses.
In our store, you can also buy accessories with an anti-reflective coating, which significantly reduces eye exhaustion by increasing the transparency of the lenses.
