Truth #3 Ready-Made Readers Are Not Recommended For High Lens Powers
Just a little educational information is required here for a full understanding. P.D./ pupillary distance is the measurement your optician takes to make sure that the center of the lens , which is also the point where you have the clearest vision, lines up with the center of your eye. It should be taken for your distance correction and separately for your reading/near correction since your eyes converge when you read. This simple measurement is important and especially important as the lens strength increases. Any lens strength above a +3.00, in ready-made reading glasses whose P.D. is pre-set, may cause some eyestrain as you may not be looking at the point of the lens that is unique to you that will also give you clearest vision. Ready -made readers are good but not for long periods of reading. This is really a simplified explanation.
Truth #2 Ready-Made Readers Don’t Correct For Astigmatism
This is true. But it really depends on how much astigmatism you have. Anything above a 1.00 in the cylinder box of your prescription would best be corrected by prescription reading glasses. This is very subjective. Some people with lesser amounts of astigmatism may feel the need for their astigmatism correction and some people with even more amounts of astigmatism may not. Over the counter readers will correct you, but for long periods of reading, prescription reading glasses will most likely provide you with the most clarity. BTW, this also goes for people who have considerably unequal corrections in both eyes.
Truth #1 Not All Reading Glasses Are Created Equal
Better quality frames last longer. They fit better and they are able to withstand every day wear and tear. Better quality lenses mean clearer vision. Optical quality lenses means the best vision you can have without getting prescription (custom made) reading glasses.
Why do optical quality lenses give you the clearest vision? They are made from high quality plastics that meet certain ophthalmic standards. Free of waves, imperfections and providing true visual clarity, optical quality lenses allow you to see clearly effortlessly. If your eyes are struggling to see through a lens that is less than totally clear you will tire easily and may even get headaches or feel dizzy. If you don’t want to spend a lot of money on your readers because you often lose them or you find that you need to keep several pairs handy, here’s what I suggest. Invest in a few good pair of readers for those times that you want to do reading for more than just a few minutes. Drug store readers are good to keep handy for quick reads…a label, a menu…but when you need to read something for any extended period of time, optical quality readers will give you clear, comfortable vision.
At some time or another we have all heard the phrase that your eyes are the windows to your soul. Dating back to biblical times, this phrase is still used today to describe the telltale clues your eyes hold as to your true self. Your eyes are also the windows to your health. Indicators of pending health conditions drop clues in your eyes sometimes before they show up somewhere else. Systemic conditions such as diabetes, hypertension and inflammatory conditions such as crohn’s disease, colitis and lupus not to mention some forms of cancer leave clues your eye doctor can pick up without you saying a word. Genetic syndromes, nutritional and vitamin deficiencies, even signs of stress show up. Annual eye exams that include dilation are important not just for getting an updated eyeglass prescription but also for monitoring your overall health.
