Retina examination isn’t just meant for an individual with eyeglasses. It is vital for everyone, especially for those who have crossed the age of 45.

Just like your physical health reduces with age, so does the visual strength of your eyes starts to decline. For those wearing glasses undergoing retina examination frequently is essential.

Moreover, those who are 45 and above must also consider routine eye exams at least once every year as the risk for retina disorder and glaucoma increases. So, one must get a dilated examination and complete a test for retinal diseases. If you wear contact lenses or glasses, you have chronic diseases like diabetes, which increases the risk of eye disease, and even those individuals who have a family history of eye disease.
