Retinoscope

A retinoscope is a handheld device used by eyecare professionals to determine whether your eyes are “20/20,” or have difficulties in seeing things up close or far away.

By shining a light back and forth across your eye, eye doctors are able to determine (usually with great accuracy) if your vision needs corrective lenses by “dialing” the retinoscope so that the light focuses properly at the back of the eye on the retina.

This simple procedure is called a retinoscopy.

During a retinoscopy, if light focuses in front of or behind your retina, you have what is called a “refractive error” of the eye. This means you may have difficulty seeing things up close (farsightedness) or difficulty seeing things in the distance (nearsightedness). And means you likely need prescription lenses or contact lenses.

Many times, your eye doctor can determine your exact prescription by using only a retinoscope, though other equipment during an eye exam will be used to completely study your eye health, and verify any refractive errors that require you to get glasses or contact lenses.

How does a retinoscope work during retinoscopy?

Retinoscopy is a relatively quick and pain-free procedure, though your eyes may water or tear up slightly when exposed to the light within the retinoscope.

Other high-tech equipment like autorefractors are becoming more common as well, as they take retinoscopy measurements automatically in just a few seconds.

The retinoscope is a handy examination tool that can automatically detect a possible vision problem. A retinoscopy can be especially good for young children or people with special needs who might have problems accurately describing “what’s wrong” with their vision.

Most people between the ages of 40-45 start to have difficulty seeing up close. This is called Presbyopia and slowly progresses until about the age of 65. This is a normal change due to the lens in the eye hardening and losing flexibility.

Vuity is 1.25% pilocarpine. This is not a new drug. It has been on the market for decades and is used to temporarily shrink the pupil size. It is now being rebranded as a drop that can help improve near vision. How does this work? By shrinking the pupil size, physics tells us this can increase our depth of focus. This drop will not CURE presbyopia. It can improve it while the drop is active and the near blur will return when the dose wears off after approximately 4-6 hours. This drop is recommended for individuals ages 40-55.

Dosage: one drop in each eye once per day. Side effects: possible brown ache or a mild headache. The cost at this time is about $80-90 per month at most pharmacies and insurance does not apply.
