As we get older, it's natural for our vision changes.<\/a> However, not all visual problems manifest themselves immediately or clearly. Many adults experience subtle - but significant - symptoms that can indicate changes in visual acuity, refraction or even more complex eye diseases. Being aware of these signs is essential for <\/a><\/span>early detection of visual problems<\/b> and act in time.<\/span><\/p>\n

Below are the <\/span>5 most common silent symptoms<\/b> that justify a <\/span>specialised optometric assessment<\/b>.<\/span><\/p>\n

\u00a01. Frequent or localised headaches<\/b><\/h3>\n

Frontal headache (in the forehead area) or occipital headache (back of the head) can be associated with <\/span>constant visual effort<\/b>. People with uncorrected hyperopia, for example, force the visual system to focus up close, which often results in fatigue and pain. Also <\/span>astigmatism<\/b> uncorrected can cause visual discomfort and pain associated with focussing.<\/span><\/p>\n

 <\/p>\n

2. Feeling of blurred vision at certain times of the day<\/b><\/h3>\n

This is one of the most overlooked symptoms. Vision that seems clear in the morning but becomes blurred towards the end of the day may indicate <\/span>progressing myopia, initial presbyopia or digital eye fatigue<\/b>This is especially true for those who spend many hours in front of a screen. In these cases, the visual system undergoes prolonged strain and loses its ability to adapt to focus.<\/span><\/p>\n

 <\/p>\n

3. Need to move mobile phone or book away to see better<\/b><\/h3>\n

Difficulty focussing on close objects, usually after the age of 40, is one of <\/span>typical sign of presbyopia<\/b> - a natural condition related to the loss of elasticity of the lens. Although common, it must be corrected with appropriate lenses to avoid eye strain, headaches and incorrect postures.<\/span><\/p>\n

 <\/p>\n

4. Increased sensitivity to light (photophobia)<\/b><\/h3>\n

If the eyes react with discomfort to sunlight or bright environments, there may be <\/span>changes in the cornea, retina or imbalances in tear production<\/b>. Certain diseases such as early-stage cataracts or uveitis can also manifest as progressive photophobia.<\/span><\/p>\n

 <\/p>\n

5. Squinting to see better (unconscious eye strain)<\/b><\/h3>\n

Many people do this automatically when watching TV, driving at night or looking at signs. This involuntary gesture is one of <\/span>clearer signs of uncorrected myopia or astigmatism<\/b>It can worsen over time if it is not assessed.<\/span><\/p>\n

 <\/p>\n

The importance of early assessment<\/b><\/h2>\n

\"retina\"<\/p>\n

Problems such as <\/span>myopia, hyperopia, astigmatism, presbyopia or dry eye<\/b> have a solution - but <\/span>the earlier they are detected, the more effective vision correction is<\/b>. In addition, optometry examinations help to detect silent conditions such as <\/span>glaucoma, macular degeneration or diabetic retinopathy<\/b>.<\/span><\/p>\n

No <\/span>Centro \u00d3ptico Ib\u00e9rico<\/b><\/a>Optometry appointments are carried out with state-of-the-art equipment, allowing for an accurate and complete assessment. If you experience any of these symptoms - even slight ones - don't wait for obvious signs. Sight is one of the most valuable senses we have.
