New Year, new vision, who knew?

I give to you the Hoya Recharge Lens. The potential problems with blue light emitted from our digital devices range from blur to eye fatigue. Filtering that high energy light is technically beneficial and possible. Look into Hoya Recharge EX3 for your next lens if you want to optimize your vision while enjoying your time viewing your phone or tablet. I did and I like them quite well.

Contact Lenses blurry? Let me count the ways.

There are so many reasons that your contact lenses may be blurring your vision, here are some for your consideration:

1. Your prescription is incorrect. Sounds simple enough. I can tell you that the art and science of determining the baseline prescription of a person's visual system is not for the simple minded. It takes serious communication, instrumentation and technique to get this right.

2. The lens is ill-fitting. The best fitting lens requires that the following factors are analyzed and considered: and this is just to name a few...

• corneal diameter
• corneal topography
• eyelid position
• eyelid tension/laxity
• eyelid friction
• tear quantity
• tear quality
• lens diameter
• lens curvature
• lens lubricity
• lens modulus

3. The lens is, for lack of a better term, dirty. Lenses can be coated with oils, mucous, makeup, fingerprints, solution chemicals and probably air born contaminants.

I suppose the next time you experience blurry vision with your contact lenses in place you can start to consider some of the possibilities. Thanks for reading.

See well,
