If you have trouble seeing and subsequently need to get prescription glasses, you'll need to see an optometrist. They can perform tests to find out what vision you have and what corrective lenses are needed. Just make sure you use these services in the following ways.

Be Descriptive During Eye Exams

The first part of identifying vision problems and selecting prescription glasses for them is going through an official eye exam. Your optometrist will have you look at letters using different prescription lenses to see what's going to work for your personal vision needs.

You just need to be descriptive during these exams, telling them what you see and how clear the letters come through. This will help the optometrist narrow down optimal lens options until you have the right prescription glasses to use after this visit is over.

Find the Right Frames

Once you work out the lens part of getting prescription glasses for vision problems, the next thing to consider is the frame that will hold the lenses in place. Don't be afraid to be picky either. You need a frame style that's comfortable to wear and is going to hold up well. 

Your optometrist should have examples of different frame options for you to test out at their facility in person. Just try to find frames that give you the most confidence and also have the right aesthetics, so that you can feel good about having to wear glasses in order to see clearly.

Let an Optometrist Know if Your Vision Changes

Just because you get a particular type of prescription glasses after consulting with an optometrist, doesn't mean this prescription won't ever change. Your vision may get worse over time, and if it does, you need to communicate these changes to your optometrist.

They can have you go back through vision testing to see how much worse your vision has gotten since the last time they saw you. Then you'll get an up-to-date prescription that helps you see clearly again. Keep doing this any time you think your vision gets worse, even if it's just a slight change.

People with vision problems can often treat them with prescription glasses, which you can easily get if you make an appointment with an optometrist and have them perform vision tests. As long as you handle them correctly, you'll get prescription glasses that help you see and are comfortable to wear long-term.
