Can Glasses Actually Make Your Eyesight Worse
Sight is the sum of the light receptive and integrative capacity of the eye including best vision, color vision, night vision, depth vision, field of vision and the ability to track objects in motion. An ophthalmologist can measure these and determine the function of ...Read more
No: This is a common misconception. Wearing glasses to correct refractive error does not make your vision worse or increase your refractive error over time. Refractive error is an imbalance between the length of your eye and it's optical power. Glasses simply compensate for that imbalance. ...Read more
No effect on sight: If you think of your eye as a camera, having a properly focused lens gives clearest picture possible, but the lens itself does not change the camera. The need for glasses comes from the eye not having the right shape or length. Glasses compensate for the physical abnormalities of the eye, but do not change the eye. So, using glasses does not help or worsen the natural sight. ...Read more
Transiently: Squinting artificially lengthens the eye a little ; allows someone to see things at a distance more clearly. This is the problem of the nearsighted(can see ok near).It is likely worse than 20/40 vision which is the level most kids start having trouble seeing the blackboard at school. ...Read more
A balance: For reading, there is a natural decline in focusing ability throughout life that becomes more problematic between the mid-40's and early 50's. The eye is comfortable with focusing about half of its full ability, so using reading glasses that do part of the work while the eyes do the rest maintains a comfortable balance. Trying to force reading without help leads to more problems like eyestrain. ...Read moreSee 2 more doctor answers
No: Glasses are designed to improve the focus of the eye and improve clarity. Sometimes patients who start wearing readers feel that their near focus becomes more difficult and to a certain extent this is true. But eventually, readers become essential whether glasses are used initially or not. ...Read moreSee 1 more doctor answer
Not at all: Glasses do not worsen the eye's vision. They serve to improve the vision by supplementing the prescription that your eyes need to see sharply. Reading glasses are magnifying lenses that improve the focus of eyes that can no longer focus well on their own. Our ability to focus up close decreases naturally as we age; glasses simply correct for this and don't cause it. ...Read moreSee 1 more doctor answer
Old message: There is a common feeling that wearing glasses will somehow affect the focusing ability of the eye in a permanent way. There is no evidence for this. A special case is hyperopia (farsightedness) which in the 20-40 age group, will get headaches without glasses which relieves that but causes more blur in between when the glasses are not worn. Wear glasses to see better - that is all. ...Read more
No: While the carotene in carrots is essential for vision, the diet in the 1st world has so much of this that deficiency is vanishingly rare. Taking an excess is no helpful - the eye grabs what it needs from the blood stream and cannot store any. The issue of carrots relates to a wwii myth by the british to fool the luftwaffe into not understanding the help from radar (look it up). ...Read more
Reading glasses: Reading glasses or bifocals are part of aging. It's going to occur. The muscles in the eye that focuses up close weaken and the lens becomes less flexible. When you use reading glasses, these muscles do not have to work as hard, so the weaken more. But this is a normal pattern. It's like buying a pair of pants with a larger waist size, they feel better, but you'll probably never go back ...Read more
