Why You Should Get an Eye Test Every Year

Most people only visit the optician when something bothers them: their vision is blurry, their eyes are irritated, or they need new glasses because their old prescription no longer works. But visual health, just like general health, works much better with prevention. A complete eye examination every year can detect problems that aren't yet causing symptoms, protect your long-term vision, and save you more costly treatments down the line.

At Óptica Florit, with over 50 years in Barcelona's Eixample neighbourhood, we carry out full eye examinations with no referral needed. In this article, we explain why this annual visit matters more than you might think.

What exactly is an eye examination?

An eye test is not simply checking whether you can see clearly or not. A thorough examination at a quality optical centre includes:

• Visual acuity: how sharply you see at different distances
• Refraction: whether you need correction and what your exact prescription is
• External eye health: condition of eyelids, conjunctiva and cornea
• Intraocular pressure: non-contact glaucoma screening
• Fundus examination (when indicated): inspection of the retina and optic nerve
• Binocular vision: how well your two eyes work together
• Visual field: detection of areas of lost vision
• Dry eye assessment: whether your eyes produce and distribute tears properly

All of this, combined with your personal history and visual habits (screens, reading, sport), allows for a far more complete picture than a simple prescription check.

7 reasons to get your eyes tested every year

1. Prescriptions change gradually, without you noticing

The human eye has a remarkable ability to adapt. Myopia or astigmatism that has increased gradually can go unnoticed for months, because the brain compensates. The result: headaches, eye fatigue at the end of the day, or finding yourself moving closer and closer to the screen without understanding why. An annual check-up detects these changes before they cause noticeable symptoms.

2. Glaucoma doesn't hurt until it has already damaged your vision

Glaucoma, one of the leading causes of preventable blindness worldwide, rarely causes pain or symptoms until it has destroyed a significant portion of the visual field. The only way to detect it in time is by measuring intraocular pressure and examining the optic nerve regularly. With early diagnosis, treatment can halt progression and preserve vision for the rest of your life.

3. Macular degeneration begins silently

Age-related macular degeneration (AMD) is the most common cause of central vision loss in people over 50. In its early stages it produces no clear symptoms: the image may distort slightly or a small blurry patch may appear in the centre, but many people put it down to tiredness. Detecting it early allows preventive measures to be taken and, in the wet form, enables treatment with intravitreal injections that halt its progression.

4. Diabetes and hypertension show up in the eyes

The retina is the only place in the body where we can directly see blood vessels without surgery. This is why a fundus examination can reveal signs of diabetic retinopathy, arterial hypertension or even cardiovascular risk before the patient knows they have these conditions. At Florit, when we detect something suspicious, we refer you to your GP with all the relevant information.

5. Children don't know they can't see well

A child who has always seen a certain way has no reference point for what "normal" vision looks like. This is why amblyopia (lazy eye) or moderate hyperopia can go undetected for years, affecting school learning and causing permanent visual development problems. A first eye test is recommended before age 3, followed by annual checks throughout childhood.

6. Dry eye syndrome gets worse without treatment

With the exponential increase in screen use, dry eye has become one of the most common complaints in optics. Many people mistake it for allergies or tiredness. Left untreated, it can progress and damage the ocular surface. An examination can identify it, distinguish whether it's due to insufficient tear production or poor tear quality, and recommend the appropriate treatment.

7. Your glasses or contact lenses may be out of date

Using optical correction that no longer matches your current prescription doesn't just mean you see worse: it can cause eye fatigue, headaches, dizziness (especially with progressive lenses) and difficulty concentrating. An annual check-up ensures your correction is always up to date.

How often should you get your eyes tested?

What happens if you skip eye tests for years?

The biggest risk of skipping check-ups is detecting late conditions that are entirely treatable when caught early. Glaucoma, AMD, diabetic retinopathy and even certain ocular tumours cause no pain until advanced stages. By the time the patient notices something is wrong, the vision loss may already be irreversible.

In contrast, the same diseases detected early have an excellent prognosis: glaucoma is managed with drops or laser treatment, wet AMD responds well to intravitreal injections, and moderate diabetic retinopathy can be stabilised with good metabolic control.

Is an eye test covered by the Spanish national health service?

In Spain, the national health service (Seguridad Social) covers a full ophthalmological examination through a specialist, but with waiting lists. Preventive periodic check-ups at an optician are not covered, although they are quick and accessible: at Óptica Florit, we carry out complete examinations by appointment, without waiting, on the same day.

Many private health insurance policies (Sanitas, Adeslas, Asisa, DKV, Mapfre Salud) do include annual optical check-ups in their cover. Check your policy or ask us and we will help you find out.

Warning signs you should never ignore

Although the annual check-up is the cornerstone of visual health, there are symptoms that require an urgent visit — don't wait for your annual appointment:

• Sudden loss of vision in one or both eyes
• Floaters (myodesopsia) appearing suddenly or in large numbers
• Flashes of light (photopsia)
• Sudden double vision
• Red eye with intense pain and reduced vision
• Distortion of straight lines (sign of wet AMD)

If you experience any of these symptoms, go to A&E or contact us immediately.

Eye examinations at Óptica Florit Barcelona

At our Eixample practices, we carry out full eye examinations with the latest equipment:

• Autorefractometer and keratometer for an objective measurement of refraction
• Corneal topographer for contact lens fitting and keratoconus screening
• Non-contact tonometer to measure intraocular pressure without touching the eye
• Perimeter for the visual field
• Ophthalmoscope and retinal camera for the fundus examination
• Binocular vision and stereopsis tests

Our registered optometrists take the time each examination requires. This is not an express appointment — it is a full exploration with a personalised report and recommendations.

Frequently asked questions about the annual eye test

How long does a complete eye examination take?

Between 30 and 45 minutes, depending on the tests needed for your profile. If a fundus examination with pupil dilation is carried out, it may take up to 90 minutes (and you will need to avoid driving afterwards).

How much does an eye test cost at Óptica Florit?

The basic eye examination is free of charge at Óptica Florit for customers. A complete examination with retinal imaging or additional tests has an affordable cost that we will tell you when you book. Many private insurance plans cover it in full.

Can I have an eye test even if I don't wear glasses?

Absolutely — and it is especially advisable. Many people with perfect distance vision have mild hyperopia that the eye compensates for with muscular effort, causing fatigue. And glaucoma or AMD screening is just as important for people who don't wear correction.

From what age should children have eye tests?

The first eye test is recommended between the ages of 3 and 4, before starting primary school. If there is a family history of strabismus, amblyopia or high prescription, it can be done earlier. Annual tests are then recommended throughout school age.

Does an eye test also detect glaucoma?

Yes. Measuring intraocular pressure is part of the standard eye examination protocol at Óptica Florit. If we detect elevated or suspicious pressure, we refer you to an ophthalmologist with all the information needed to complete the assessment.

How often should older adults have eye tests?

From the age of 50 we recommend annual examinations without exception. The risk of cataracts, glaucoma and AMD increases with age, and early diagnosis makes the difference between preserving vision and losing it progressively.

Conclusion: the best investment for your visual health

An annual eye test is not a luxury or simply "a visit to change your glasses". It is the most effective tool for protecting your vision throughout life, detecting systemic diseases before they cause symptoms, and ensuring your optical correction is always optimised.

At Óptica Florit, we have been caring for the visual health of Eixample residents for over five decades. If you haven't had your eyes tested in the past year, or if you have any concerns about your vision, book an appointment at our practices on Carrer Diputació or Mandri. An eye test is the first step towards healthier, longer-lasting vision.
