How can you know that your child needs prescription eye glasses? Sometimes, children don't even realize that they aren't seeing clearly until their vision is very bad. My son was in third grade when I found out that he needed glasses. He was suffering from headaches and I noticed him constantly squinting. The only thing that made me realize that all of his problems were because he needed glasses was the school nurse contacting me to ask if I had ever taken him to an eye doctor. From that point on, we have had to find glasses that could withstand the abuse that he put them through and safety glasses that he could wear to play sports. This blog is all about children's eye care and finding glasses for them.
