My Glasses Cause Eyestrain when Looking Up Close

Glasses prescriptions usually are pretty good. Quality eye providers provide quality prescription measurements. Occasionally, however, the glasses may be a little off. Sometimes the vision can be blurry when the prescription of the glasses is a little off, but sometimes it just doesn’t feel right. Despite having good vision when performing up close work, the eyes begin to ache. Closing the eyes or resting with other non-up close work gets the achiness to fade away. Strange, huh?

There is a muscle inside the eye that gives us our ability to focus. When we look up close this muscle contracts, when we look off in the distance this muscle relaxes. Ache problems start to happen when this muscle is overworked. Normally this muscle isn’t very stressed when we look at normal things up close. But if you start to stare at things directly in front of your face, this muscle will start to ache.

When we are being measured for a glasses prescription, this particular muscle loves to focus. If you add prescription that this muscle can focus through, it will eat that prescription right up. Too much and this leads to excess prescription that the eye doesn’t need. This leaves this muscle in a chronically contracted state focusing through this excess prescription. But the real ache occurs when this muscle must contract even more to focus up close!

So how is this fixed? Pretty simple, just a fix in the glasses prescription is needed. Dilating the eyes during the prescription measurement ensures that this muscle stays nice and relaxed. Which in effect, keeps the eyes feeling comfortable in our ever increasing up close world.
