Are there ways to avoid age-related refractive errors?

Are there ways to avoid age-related refractive errors?

Not really: You are probably referring to the hardening of the lens which occurs with age (presbyopia) which inhibits the ability to see at near unless near corrective lenses are worn. There is no way to avoid this universal condition of humans but your ophthalmologist can offer ways to compensate using proper eyeglasses and certain types of contact lens. ...Read more

Are there ways to avoid age-related refractive errors?

Don't get old: All kidding aside, age-related refractive error changes are usually inevitable. As we get older the lens in our eye changes and its ability to bend light changes thus affecting refractive error. As we get older we also lose her ability to focus up close, a condition called as presbyopia. A few unlucky patients who are very nearsighted may also have progression of their myopia as they age. ...Read more

Do eye diseases affect refractive errors?

Do eye diseases affect refractive errors?

Sometimes: The focus of the eye is greatly affected by the lens - diseases such as cataract and presbyopia can dramatically affect the focus. Sometimes corneal scarring may induce astigmatism and keratoconous may cause irregular astigmatism requiring contact lenses to treat. ...Read more

Can eye exercises prevent or correct refractive errors?

Can eye exercises prevent or correct refractive errors?

Not really: Refractive errors are intrinsic to the eye structure and are best corrected with glasses, contact lenses or lasik. In some cases of early presbyopia or difficulty reading, reading glasses may be delayed a bit with accommodation exercises but inevitably patients will require reading glasses. ...Read more

My 6 month old baby was diagnosed with infantile esotropia. she has slight refractive errors. what do you say about botox in the eyes to improve eyes?

My 6 month old baby was diagnosed with infantile esotropia. she has slight refractive errors. what do you say about botox in the eyes to improve eyes?

Other choices ?: Botox injected into any of the 6 muscles that control the eye position can help balance the process. It selectively weakens a specific muscle in an effort to improve how the eye lines up. In experienced hands it is one way to treat the problem. My thought would be to try less invasive treatments first. ...Read more

Surgical reshaping of the eye is done to correct visual pathology and orthodontics corrects dental arch pathology, other than that, I am unable to help you with an intelligible answer! ...Read more
