Arranging a home eye examination You can arrange for an optometrist to visit your home to carry out, as far as possible, a full eye examination.

Home vision tests should be performed under the direction of your health care provider to detect changes that may occur between eye exams. They do not take the place of a professional eye exam.

There are many potential drawbacks to taking an online vision test. They're not as accurate as in-person eye exams, so you can't detect if you have astigmatism or other refractive errors. They can't detect all types of vision problems, like glaucoma or cataracts.

Thankfully, if you have a pretty basic prescription (meaning they're not bifocals, progressives or Coke-bottle lenses), there's a free tool from GlassesUSA.com that can scan your current glasses. I took it for a spin with my son's glasses and the results matched his current prescription.
