Online eye examinationOpternative is a new company that wants to offer eye tests and prescriptions for new glasses or contacts via your computer's browser. Clearly sick and tired of hearing people saying how staring at a computer screen is bad for your eyesight, the company's big idea is to dramatically simplify and streamline the current process for consumers who need to get new lenses or who are simply concerned that they might need to get a quick check-up just in case.

As well as being cheaper than a traditional appointment with an optician, consumers using Opternative won't need to do any legwork at all. No need to track down an eye doctor in the local area or have to take an appointment. In fact the company claims that the online test takes just 10 minutes, and the resulting prescription can be used anywhere. The company is not the only one offering online eye tests, but it is the only one that will be offering a true medical-grade exam when it officially launches this summer.

And unlike a number of techy businesses attempting to disrupt or move into the health space, Opternative was co-founded by an experienced ophthalmologist, Dr. Steven Lee, who believed there must be an easier way to provide people with his services.

Although the company is now offering interested consumers the chance to sign up and register interest in using the service, Opternative won't be launching in its native US until this summer when it hopes to have obtained full FDA approval. And until it does, its founders are keeping the details of the exams, including their look and feel, a secret. (Read: Why should you visit an eye doctor regularly)

When should you start eye check-ups

Have your eye tested regularly till you are 40 and every two years hence forth. If you are wearing contact lenses, get your eye exam done yearly. Children should have vision screening once they start going to school and then every year or two. Even if you have no problems with your eyes, make sure to visit the eye doctor once or twice a year after the age of 65, to rule out eye complications.

How long will an eye exam take?

That will depend on whether it's the first time you are visiting the doctor or if you are going for a follow up visit or just regular check ups. It may take about an hour or so if it is your first visit since the doctor will have to do a complete eye exam. Follow ups won't take this much time.

What to expect during routine eye exam?

The first thing the doctor will ask you is whether you are having any vision or eye problems. And if yes, then how long you had them and what makes them better or worse. The doctor will then review your history of glasses or contacts and ask questions about your overall health, if you are taking any medication, and also your family's medical history if required, followed by various tests such as

  • Visual acuity test to check your vision with the help of Snellen chart. The Snellen chart is used where you will be asked to read random letters that become smaller line by line as your eyes move down the chart.
  • Diopter test or Refraction test to see if you need glasses. If you are approaching 40 years of age or more and find it difficult to read close up, the doctor will place several lenses in front of your eye (or use a special device called refractor attached to your chair), one at a time, and ask you when the letters on the Snellen chart become easier to see.
  • Slit-Lamp Examination to evaluate your eye health and detect any signs of infection or disease. You place your chin on the chin rest of the slit lamp and the doctor will then shine the lamp's light at your eye and examine each part of your eye one by one.
  • Keratometry to measure the curvature of the cornea. Your doctor will focus light on the cornea and measure its reflection. Its especially useful in determining the proper fit for contact lenses.

Other eye tests where the doctor will

  • Check if you have proper three-dimensional (3D) vision (stereopsis);
  • Check your peripheral vision (visual field test);
  • Check the eye muscles by asking you to look in different directions at a penlight or other small object;
  • Examine the pupils to see that they respond properly to light;
  • Check the inside of your eyes with an ophthalmoscope (ophthalmoscopy);
  • Check the back of your eye by giving eye drops to dilate your pupils to view the structures in the back of the eye (retinal examination).

Many eye diseases are curable or can be treated if detected early. Read more about the eye tests you need to take.
