Do eyeglasses really help bad night vision?

Do eyeglasses really help bad night vision?

Yes: At night, your pupils dilate. This (along with a few other changes that occur at night) may cause a temporary change in your glasses prescription leading to "night myopia" or slight nearsightedness at night. This makes many people feel as though they have "bad night vision" but really a small glasses prescription to be worn at night particularly while driving can help night vision. Read more

Vision (Definition)

Vision is a feature of a person's brain that allows him to see. He must have normal eyes, optic nerves (that stretch from the eyes to the back of his brain), and visual cortex (the vision center in the brain), in order to see properly. An ophthalmologist is a ...Read more

Are there glasses that can increase your night vision?

Are there glasses that can increase your night vision?

Yes: In some patients adding a negative 1/2 diopter improves their night vision. Also night vision goggles can improve your vision at night. Spending several minutes in the dark, adapts your rods so you can see better. Use a red light flashlight to avoid loosing your dark adaptation. Don't forget that wild cats have 6 times better night vision than humans, so be careful out there. :). Read more

How do anti-glare night vision glasses help with difficulty driving at night?

How do anti-glare night vision glasses help with difficulty driving at night?

Less light scatter: Glare is caused by scattering of light before it enters the eye. Anti-glare lenses filter certain wave lengths of light, resulting in a more uniform beam of light entering the eye. Yellow or amber tints are best. Read more

I've been having diminished night vision and diminished vision during the day wearing sun glasses. I had lasik surgery 13 yrs ago. Any suggestions?

Diminished vision: There are many potential causes of diminished vision under low illumination including cataracts, low vitamin a levels and other disorders. This may have nothing to do with your lasik. Please see an eye doctor for a thorough eye exam. Read more

Bad night vision due to too much time spent in front of the monitor & tv. What do you suggest?

Evaluation: Overuse of a monitor or tv can lead to fatigue but will not cause bad night vision. There are other causes for this and it depends of course on "how bad". You should consult with your ophthalmologist to determine the level of night difficulty and what can be done about it. Read more

My right eye has really bad night vision help me plz?

Is this chronic?: If this is a longstanding condition (as far back as you can remember) it is likely permanent. If it started recently (over the last few months or a few years) there may be a cause that can be treated. I recommend having a dilated eye examination. Read more

I have very bad night vision, and anything that is lit. I've always been light sensitive. What could cause this?

Many causes!: Without an exam it is difficult to tell you what is going on. It sounds like you have always been this way, in which case it is 'normal for you'. Just like some people are cold sensitive (always need a sweater), some people are light sensitive. At the age of 48, you could also have early cataracts, which would decrease your night vision.

Is it bad for your eyes to go back and forth from night vision to regular vision quite quickly for maybe an hour period?

Is it bad for your eyes to go back and forth from night vision to regular vision quite quickly for maybe an hour period?

Not bad for the eyes: There is no physiologic basis for the eyes to become strained or damaged in any way as a consequence of normal levels of light (not like a laser beam focused on the retina) alterations. I have no idea what this will do to your circadian rhythms though. Good luck with that one. But the retinas and corneas and lens will be fine. Read more

If I have poor night vision, does that mean that my eye health is pretty bad?

Get checked out: Although reversible loss of night vision may be associated with vitamin a deficiency, this is not likely in developed countries with normal diet. How long have you had poor night vision? Do you have congenital hearing loss? Loss of night vision may more likely be secondary to a variety of retinal dystrophies, including, most notably, retinitis pigmentosa (rp). When associated with congenital hearing loss, rp is part of usher’s syndrome. Symptoms are progressive nyctalopia (night vision loss) and constriction of visual fields (ie: inability to see immediate surroundings like stair rails or peripheral traffic when gazing forward). Other conditions may cause similar symptoms but are less common. Diagnosis is made by ophthalmologic examination including ophthalmoscopy, erg and visual field testing. Cataracts may occur and further impair vision. Unfortunately, there is presently no recommended therapy to arrest or cure these conditions but research is being conducted into the effects of neuroprotective agents as well as surgical remedies with stem cell and retinal pigment epithelial replacement. Please have your eyes dilated and examined. Read more

Is it bad that I need glasses but I don't want to wear them? What are the effects of that? Would it worsen my vision?

Hard to say: If both eyes are at a similar strength the brain would probably just give you fuzzy vision.Over time, all vision can gradually change anyway. If one eye is stronger than the other, or gives a sharper image, the brain may eventually turn off the vision in the weaker eye. Without vision, that eye may no longer track or line up straight with the other, leaving you cross or wall eyed. Read more

Is it bad to wear reading glasses a lot if you have good vision?

Is it bad to wear reading glasses a lot if you have good vision?

No...: ...But it may cause undue strain. Up until the 40s, the eyes can normally focus for near work. By the late 40s, near focus becomes difficult. Reading glasses are essentially magnifiers that help you focus up close. If you can focus up close on your own, there is no reason to use readers, and they can give you headaches. There is no danger, however, in using them. Read more

No: It will not harm his eyes. Over-the-counter reading glasses are good magnifiers and make it easier to see close objects, . They can be useful to anyone, even children, for this purpose. If your child wears them alot, it is possible they need glasses and an eye exam is advised. Read more

If one has perfect vision, is it bad to use reading glasses; will it mess up the perfect vision?

If one has perfect vision, is it bad to use reading glasses; will it mess up the perfect vision?

Shouldn't: All depends on what you define as perfect vision. If that has been assessed by an eye care provider, then reading glasses are merely extra magnification and shouldn't interfere with your vision. However, if you have any residual farsightedness or other type of prescription at distance, sometimes this can become more manifest, or noticeable, after wearing reading glasses. Read more

What do you suggest if I got my glasses today. My vision isn't terribly bad, they were mainly for them for a few days consistently to get my eyes acclamated, is this ok?

What do you suggest if I got my glasses today. My vision isn't terribly bad, they were mainly for them for a few days consistently to get my eyes acclamated, is this ok?

May need a check: Return to see you eye doctor If you are still having problems after a week. The prescription may be off or the glasses could have been made incorrectly. There is usually no charge for this and most optical places will remake a prescription at no charge if done with a certain time. Usually, 90 days. Read more
