Many parents have a lot of trouble persuading their youngsters into wearing glasses, which is necessary because of vision problems…
If the child is older than three years, try to talk to him, explain to him that the glasses will help him and if you show that with an example you’re already on a half-way to success. The role of children’s eyeglasses is firstly and mostly correction of vision. Glasses should fit well and therefore it is necessary to find a model that fits the anatomy of a child’s head. The best solution is lightweight, stable and flexible frame made of anti-allergic material.
You can find many plastic and metal frames for children. Metal frames are thinner and are easily repairable. Plastic frames adhere to the nose better and therefore can often be a more comfortable choice. Also there are frames made of titanium, which is hypoallergenic and is also the easiest material.
The most important are the lenses in the eyeglasses. Given the material, there are two types of lenses: plastic and mineral (glass). In the case of children’s glasses the better choice is definitely plastic ones because they are more resistant to breakage. It should be noted that children’s glasses break quite often! Also, there are lenses made of polycarbonate, which are extremely resistant to hits. Children’s lenses should have a UV filter, anti-reflective layer and hard layer (coating that protects the lens from scratches).
And finally a few tricks: in choosing the right eyeglasses for your child, the best help you can get is from experienced optician, who will tell you how much of the cost is covered by health insurance. Always good to have spare glasses, so you do not have problems in case of an accident.
